The standard wood pallet is 36" x 48" in size with 2" x 3" high runners. The capacity of such a pallet ranges from approximately 450 to 500 -- 9" equivalent in fire clay and silica refractories and 300 to 400 -- 9" equiva lent in high alumina and basic refractories depending on the weight factor of the type of refractory involved. Pallet loads will approximate 4000 pounds. Palletized shipments of refractories can be made by either truck or rail. Various types of pallet protection and methods of loading box cars for rail shipment are illus trated in the Refractories Institute Manual "Recommended Equipment and Procedure for the Palletized Loading and Shipment of Refractory Brick.'' References shown in this manual should be given to facilitate expediting orders for palletizing shipments. TYPES OF FIRECLAY BRICK Fireclay brick are the industry's most important product because their wide range of properties fits them for use in a great variety of refractory applications. NARCO fireclay brick plants and mines are located in Pennsylvania, Ohio, Ken tucky and Missouri where a wide variety of high-grade flint, semi-flint and plastic bond clays are available in the high est quality. In each district NARCO produces a series of brands with various combinations of properties, so that there is always available a brand to meet successfully any service condition where fireclay brick are applicable. The properties of fireclay brick are dependent primarily upon the types of clays used, the proportions of the various clays employed and the process of manufacture. The grain structure, moisture content during forming, as well as firing temperatures and procedures also influence the final product. Brick produced by the dry press method are suitable for a wide variety of service applications. The brick are formed under high pressures by sturdy mechanical presses which gives an excellent balance in the properties of the end product. The brick have good spalling and abrasion resistance and at the same time have reasonable resist ance to siag attack. They possess adequate strength and good load-bearing ability at high temperatures. The stiff mud method of manufacture gives a strong, dense product with a resulting low porosity. This tight, dense structure is highly resistant to abrasion and to the penetration of slags as well as chemical attack or solution by fluxes. Small quantities of special size tile or complicated shapes can be most economically produced by tamping press, air hammer or hand mold process. Utilizing these three processes for small runs has the special character istic of high versatility and insures careful control of dimensions and detail. All products are fired under strict control to give de sirable physical and mineral changes thereby producing strong, well-bonded brick. All NARCO brands of fireclay re fractories possess uniformity of physical properties, work manship and size of the finished product.

With their greater refractoriness, outstanding spalling re sistance, high strength, volume stability at high tempera tures and ability to withstand many types of corrosive slags, super duty brick offer the furnace builder a material for use under extreme conditions. Through extensive research, NARCO has developed super duty brands with many desirable properties to resist a combination of destructive forces. In some furnaces super duty brick are used to line only the hot spots while in others the entire hot zone is lined with super duty refractories. The decision is based on, (a) cost per unit of product treated, (b) seriousness of possible failure from use of lower quality brick, (c) cost of interruption in opera tion, (d) reduction in operating costs because of better process control and (e) insurance against unexpected interruptions. NARCO super duty brick are made from a blend of several of the purest and most carefully selected fireclays to insure a super product. In the process of manufacture, the clays are properly proportioned, ground to a definite grain sizing, formed, dried and fired by the most ad vanced, controlled methods to insure uniform quality and workmanship. NARCO 68 is a Missouri dry press general purpose super duty brick. Resistance to spalling and vitrification makes NARCO 68 suitable for a wide variety of service applications, including heavy duty boilers, incinerators, heating furnaces, ferrous and non-ferrous furnaces, cement and lime kilns. NARCO 68 brick are well known wherever super duty brick are used and have established many outstanding service records under extremely severe oper ating conditions. This widespread use testifies to the ex- mmmmmmm iiiiiBiiliiiiSi SUPER DUTY FIRECLAY BRICK (Cont'd) cel lent physical and chemical properties of this product, which results in increased service life. NARCO 68-N were especially developed for super duty service where extreme resistance to spalling is required and strength is not as important a factor. In marine boilers, swing type electric furnace roofs and similar ap plications. NARCO 68-N have provided superior service. NARCO 71 is the general purpose dry press super duty brick produced in Pennsylvania, similar to NARCO 68 in properties and application. NARCO 71 possesses remark able freedom from shrinkage at high operating tempera tures which enables tight masonry construction to be maintained throughout the life of the furnace. Excellent service records for NARCO 71, under adverse conditions, were possible because of the high quality of this product. These records have been compiled through many years of continued use by satisfied customers. HIGH FIRED SUPER DUTY FIRECLAY BRICK MOHAWK and MOHAWK BF are high fired super duty dry press firebrick compounded from Missouri materials and similar in chemical composition to NARCO 68. Spe cial heat treatment through extremely high temperature firing produces a strong, tough product of low porosity and stability of volume at working temperatures. The desirable properties of hot load bearing strength, resist ance to fluid slags and metals, stability under soaking heat and resistance to abrasion and carbon monoxide disintegration assures longer life in furnace structures operated under the most severe conditions. MOHAWK high fired super duty brick is extremely hard burned brick to provide an extra margin in physical char acteristics as low porosity, resistance to slag attack and load bearing ability. Because of these properties MOHAWK is particularly suited for bottom blocks and upper stack areas of blast furnaces which are exposed to severe abra sion by the furnace charge. These characteristics also make MOHAWK ideally suited for many other applications as glass tank checkers and rider tile, torpedo type iron ladles, hot metal mixers, non-ferrous furnaces and vari ous vertical and rotary kilns. MOHAWK BF high fired super duty brick is fired at a temperature slightly less than MOHAWK to provide greater spalling resistance and still maintain a desirable balance of physical properties. MOHAWK BF is particularly suited for the lower stack areas of blast furnaces, forge fur naces, billet and slab furnaces, reheat furnaces and other furnace applications where temperature fluctuations are encountered. HIGH DUTY FIRECLAY BRICK NARCO produces brick of high duty quality in ail the major producing districts,thus enabling the furnace oper ator to obtain just the brick for his needs, in a minimum amount of time and at a minimum cost to him. This is possible through the scientific combining of numerous types of clay and variations in the processing methods whereby a series of brands is produced in each district pos sessing a range of physical properties to combat various combinations of destructive forces present in installations. Fireclay brick are required to have properties such as high refractoriness, high density, constancy of volume at high temperatures and resistance to thermal shock, slag penetration, erosion, corrosion and abrasion. In one in stance the spalling resistance may be of prime importance in one part of a furnace while in another part of the same furnace slag penetration may be dominant. Proper selec tion of the various types of high duty refractories can ma terially lengthen the service life of such an installation. It is not unusual to use a high duty brick to withstand certain destructive forces present even when operating tempera tures indicate the use of intermediate or low duty brick. Each of our brands possesses to the highest degree the particular properties desired. This high quality was devel oped by long years of close cooperation with the users of fire brick and the adjusting of the-brick properties to suit exactly the service conditions to be encountered. MISSOURI --FARBER BRAND PENNSYLVANIA -- CRESCENT BRAND MEDIUM AND LOW DUTY FIRECLAY BRICK In general, when refractory structures are subjected to relatively moderate or low temperatures, brick of the inter mediate or low duty class give excellent service. They are strong, tough, dense and are especially resistant to abra sion and slag action at moderate temperatures. Thus they find use in cooler sections of boilers, upper parts of cupolas, cooler sections of both vertical and rotary lime kilns and Portland cement kilns, heating and annealing furnaces and many similar furnaces or portions of furnaces operated at moderate temperatures. Of course, both medium and low duty brick are used extensively as back-up materials for high and super duty fire brick in a wide variety of furnaces. The toughness and abrasion resistance of these brick enable them to suc cessfully withstand ail types of mechanical abuse from causes outside the furnace and thereby protect the weaker but more refractory inner walls. Low duty and many medium duty fire brick are resist ant to damage by continued exposure to moisture and freezing conditions. Because of these characteristics they are used widely for underground flues and foundations which are exposed to ground water and for the outside of furnaces, kilns and chimneys exposed to the weather. In many industrial furnaces, operating temperatures often call for the use of low or medium duty brick, but high or even super duty brick must be used to combat the other destructive forces present which shorten the life of the refractories. NARCO HIGH ALUMINA BRICK REFRACTORIES NARCO offers a complete line of high alumina refractories to meet the most rigid requirements of industry today. In ad dition to a wide range of alumina content (from 50% to 90%), NARCO high alumina refractories have a wide di versity of physical properties. Furnace operators may choose alumina brick for many reasons -- resistance to abrasion, impact, spalling or load, in addition to greater refractoriness, from the broad NARCO line. NARCO high alumina refractories have excellent load bear ing characteristics and unusual resistance to alkaline slags. They retain better spalling resistance at higher temperature than do high duty or super duty refractories. They are manu factured under exacting conditions of quality control to insure the customer exactly those properties he demands in the finest refractories to meet the most exacting requirements. In choosing the correct high alumina refractory for his par ticular application, the user has a choice of NARCO refrac tories with an operating temperature resistance range of nearly 200 degrees F. and a range of alumina content in 10% increments from 50% to 90%. This range of characteristics encompasses the most rigid requirements for a wide variety of operating conditions. Here is a general description of the various types of NARCO high alumina brick. NARCAL 50 NARCAL 50, with an alumina content of 50%, has a P.C.E. value of 34-35 which is more refractory than super duty brick. Other important properties are high resistance to spalling and slag attack, high mechanical strength and ex cellent volume stability at operating temperatures. NARCAL 50 is used extensively in lime kilns of both vertical and rotary types and in rotary cement kilns. NARCAL 50 brick are also used in applications where the brick are exposed to rapid temperature fluctuations or where alkali attack is severe because of high temperatures. NARCAL 60 & NARCAL 60N NARCAL 60 is a 60% alumina content brick which carries the same valuable properties to a higher temperature level. With a P.C.E. rating of 36-37, NARCAL 60 have high volume stability in the presence of lime and alkali fluxes. NARCAL 60 brick are recommended for various types of oil-fired furnaces, lime kilns, cement kilns and at the slag line of metallurgical furnaces as well as in port walls, up takes and upper checker courses of glass tanks. NARCO HIGH ALUMINA BRICK REFRACTORIES (Cant'd) NARCAL 60N is also a 60% alumina content brick with similar P.C.E. and temperature resistance. It is especially designed for severe service conditions requiring excellent resistance to spalling such as high temperature boilers, forge (and malleable iron furnace) Bungs. NARCAL 606 NARCAL 606 is a special 60% alumina brick of high density, high strength and volume stability, it is manufactured from high purity calcined kaolinitic bauxite that results in properties superior to many brick of higher alumina contents. The noted resistance to alkali attack and erosion displayed by this brick finds it widely used for blast furnace linings, blast furnace stove checkers and wall brick, hot metal cars, ladles and car tops. NARCAL 70 AND NARCAL 70 D NARCAL 70 (70 % alumina content) is furnished for appli cations which require still more refractory qualities to meet extremely severe conditions. Having a P.C.E. of 37-38, NARCAL 70 finds its widest application in the hot zones of rotary kilns producing lime,, cement and dolomite. The brick texture ensures a relatively low penetration by molten slags and softened clinker, yet It takes on and holds a satisfactory coating in cement kilns. NARCAL 70D is a 70% alumina brick especially formu lated to provide extra density and lowest porosity. These properties contribute to increased resistance to deformation under conditions of heavy loads and soaking heat as well as severe slagging conditions at high temperatures. SENECA SENECA is a 70% alumina dimensionally stable brick pro duced from high purity kaolinitic bauxites. SENECA displays the lowest porosity for this alumina class providing reduced penetration of destructive elements. Because of its high purity with the resulting low alkali content excellent spalling resistance is achieved along with limited growth at elevated temperatures and outstanding resistance to deformation under load at high temperatures. .SENECA finds wide usage in electric furnace roofs, ladles, rotary kilns and other appli cations requiring a product with improved physical and chemical properties in the 70% alumina class. NARCO HIGH ALUMINA BRICK REFRACTORIES (Cont'd) NARCAL75 C NARCAL 75 C is a 75% alumina phosphate-bonded brick. It has high strength and load bearing ability, and excellent resistance to abrasion, erosion and mechanical abuse. It may be used in air furnace sidewalls, electric furnace roofs, iron and steel ladles, aluminum melting furnaces, skid rails and furnace hearths, NARCAL 80 NARCAL 80 is an 80% alumina content brick which com bines extreme temperature resistance (P.C.E, 38-39) with high resistance to strong corrosive action of alkalies and other fluxes at high temperatures. NARCAL 80 brick also possesses excellenttherma! spalling resistance, rigidity under load at high temperatures, low porosity, high bulk density and are extremely strong (cold crushing strength 5000-9000 lb. psi.). NARCAL 80 is used where highly basic slags at high temperatures must be contained, such as malleable furnace bottoms. Also recommended for electric furnace electrode rings, and hot zones of cement kilns. NARCAL 85B & NARCAL 85C NARCAL 85C is an 85% alumina, chemically bonded refrac tory brick designed for metal contact in all types of aluminum melting furnaces. It is especially recommended for the critical bottom and sidewalls to a point 12 to 18 inches above sill level. This brick combines high refractoriness (P.C.E. 38-39) with good resistance to penetration and reaction by molten aluminum and its numerous alloys. NARCAL 85B is a high alumina brick of similar chemical composition. In this case, however, 85B is given a hard burn endowing it with a number of superior properties. Greater strength, volume stability, abrasion-erosion resist ance and load bearing properties are gained through the burning process. NARCAL 90 Highest refractoriness of all NARCO high alumina brick is exhibited by NARCAL 90. With a P.C.E. rating of 40-41, NARCAL 90 is recommended wherever operating conditions are too severe for brick with less than 90% alumina. NARCAL 90's outstanding characteristics include high resistance to thermal spalling, exceptional volume stability at high tem peratures, excellent load bearing properties and high resist ance to corrosion by slags, volatile alkalies and alkali dusts. NARCAL 9Q's exceptional properties are due to its being NARCO HIGH ALUMINA BRICK REFRACTORIES (Cont'd) composed primarily of the stable mineral, corundum. NARCAL 90 are recommended for jambs, port floors and arches, and checkers of glass tanks, aluminum melting furnaces, furnace piers and similar applications where heavy loads or severe fluxing are encountered. NARCAL X NARCAL X is a specially formulated abrasion and slag resistant brick with remarkable resistance to both at ele vated temperatures. NARCAL X contains 64-67% alumina (P.C.E. 37-38). NARCAL X brick is recommended primarily where service conditions are too severe for standard high alumina brick and where spalling is not a factor. Hearths of all types of heating furnaces, vertical lime kilns, boiler grate lines or severe wear areas of metal mixers and ladles are typical applications. NARMULL NARMULL is a special high alumina brick commonly known as mullite, a super refractory brick. Mullite brick depend upon the development and distribution of the mineral mullite throughout its structure for its outstanding properties rather than alumina content. NARMULL is made up of a blend of the best natural sillimanite and synthetic mullite bonded together. NARMULL is outstanding for its load bearing abilities, volume stability, resistance to spalling and slag attack as well as high mechanical strength and resistance to abrasion. NARMULL has proven itself outstanding in continuous butt weld furnaces, hot metal cars and rider arches, NARMULL is particularly adapted for blast furnace stove top checkers, sidewalls, and combustion chambers. It is well suited for car top block, kiln furniture, piers, etc. LADLE BRICK LX-50, LX-60 and LX-70 ladle brick provide a complete series of high alumina expanding type refractories for lining appli cation s.

The word "basic" refers to the chemical nature of the materials as opposed to "acid" refractories such as silica materials. Since chrome ore is practically neutral in nature and resists both basic and acid slags equally well, it is arbitrarily classed as a basic material. Basic brick are used for two main technical reasons: (1) the higher melting point and therefore higher permis sible operating temperature and (2) the chemical aspects that improve resistance to basic slags, oxides, dusts, and fumes. NARMAG Basic Brick have been made possible through the combination of the latest technological developments and the most modern manufacturing equipment applied to basic raw materials of the highest purity. Use of the highest purity seawater Periclase clinker, and high grade Philippine chrome ore as raw materials, bonded with a very high purity chemical binder, give the NARMAG line outstanding chemical properties. These properties in the brick are further enhanced by superior physical features achieved during manufacture through corrected grain sizing, carefully controlled batching and blending of in gredients and improved techniques in forming and metal casing. NARMAG basic refractories meet the exacting require ments of the metallurgical, glass and cement industries in ail basic compositions required (magnesite, magnesitechrome, chrome-magnesite and chrome). These varied basic compositions are available both burned or chemically bonded, plain, metal encased or internally plated, enabling the selection of a basic brick with the proper chemical and physical properties for the specific requirements of the application. DIRECT BONDED BASIC REFRACTORIES Direct bonded basic brick are characterized by the predom inance of direct attachment of periciase to periciase or periclase to chrome grains in the brick structure. Such refractories are produced from carefully selected raw materi al to achieve desired chemistries and incorporate extremely high firing temperatures to develop proper physical proper ties. The brands range in qualities from 50 to 96% MgO and display one or more of such benefits as improved slag resistance, lower porosity, greater density and outstanding hot strength properties. NARMAG 50DB - a direct bonded magnesite-chrome brick of approximately 50% MgO content. For use in copper and copper-nickel service, AOD vessels, and glass furnaces. NARMAG 60 DB - a direct bonded magnesite-chrome brick of approximately 60% MgO content. Displays high hot strength and refractoriness for applications as electric fur nace and open hearth walls, mineral,processing kilns, giass furnaces as well as non-ferrous furnaces. NARMAG 60DBR -- a direct bonded magnesite-chrome brick of 60% MgO content, it is recommended for open hearth roofs and other applications requiring good re sistance to "redox" (reducing - oxidizing) reactions. Such reactions often cause destructive growth or expansion problems with conventional grades of brick. NARMAG 608 -- a direct bonded magnesite-chrome brick of 60% MgO content displaying lowest porosity and highest density for its class. Especially recommended for use under severe slagging conditions as encountered in electric furnaces and AOD vessels. For use in burning zones of cement kilns. Protected by U.S. Patent No. 3,715,223. NARMAG 80 DB - a direct bonded magnesite-chrome brick in the 80% MgO class. The high refractoriness, greater thermal shock resistance, and excellent resistance to iron bearing slags provides an outstanding product for specific high temperature applications. SUPER NARMAG B - a direct bonded straight magnesite brick of approximately 96% MgO content. The high hot strength and excellent spalling resistance of this brick makes it particularly suited to glass furnace, rotary lime kiln and other applications requiring a chrome free product. BASIC REFRACTORIES FOR BASIC OXYGEN FURNACES The advent of the basic oxygen furnace(BOF) placed new and enormous demands on refractory requirements. This steel making process consumes huge amounts of substantially pure oxygen to convert hot metal and scrap to steel with a high degreeofthermal and chemical efficiency. This accomplishment has imposed a number of severe conditions to the refractory lining. High operating temperatures, severe impact and abrasion, wide temperature fluxuations, operating atmospheres of reducing and high iron oxide nature together with active slag conditions have dictated the need fora range of pitch bearing types of basic refractories. NARCO has played an active role in developing BOF refractories to meet the needs of the basic oxygen process. The NARTAR series includes conventional (unburned) and tempered pitch bonded varieties as well as burned pitch impregnated grades. The combining of these materials in basic oxygen furnace working linings enables balance lining wear which results in lower refractory cost perton of steel produced. Pitch-Bonded Refractories SUPER NARTAR A---A pitch-bonded 96% MgO refractory brick produced from high density synthetic periclase. it may be used in any area of the vessel where an un-tempered brick is suitable. NARTAR B -- A pitch-bonded refractory brickmadefrom a blend of synthetic periclaseand natural magnesite having an MgO content somewhat lowerthan SUPER NARTAR A. it is an economical brick for use in areas where an un tempered brick is suitable and service conditions do not warrant higher MgO grades. Tempered Pitch-Bonded Refractories SUPER NARTAR AT--A tempered pitch-bonded 96% MgO refractory brick produced from high density synthetic periclase. This brand is a premium product displaying maximum slag resistance and density. It may be used in all areas of the vessel particularly those where severe slag wear is encountered. BASIC REFRACTORIES FOR BASIC OXYGEN FURNACES SUPER NARTAR AT-M -- Atempered pitch-bonded 96% MgO refractory brick similar to SUPER NARTAR AT, but modified to provide unusual resistance to slump and spalling during burn-in and in the balanceof the campaign. It is recommended forvessel areas wherespallingmaybea problem. NARTAR BT -- A tempered pitch-bonded refractory brick made from a blend of synthetic periclase and natural magnesite having an MgO content somewhat lower than SUPER NARTAR AT. It is an economical brick for use in cones, barrels and bottoms when a higher MgO brick is not required. NARTAR BT-M -- A tempered pitch-bonded refractory brick similar to NARTAR BT, but modified in the same manner as SUPER NARTAR AT-M to provide unusual resistance to slump and spalling during burn-in and in the balance of the'campaign. It is recommended for vessel areas where spalling may be a problem and where higher MgO is not required. Burned Pitch-Impregnated Refractories NARTAR PAD -- A burned and pitch-impregnated 96% MgO brick produced from synthetic periclase of high density and low porosity. The outstanding hot strength, spalling resistance and density of NARTAR PAD provide the ultimate refractory for charge pads where resistance to the impact of scrap and hot metal during charging is important. NARTAR PAD provides maximum wear resistance in other areas of the vessel and may be used for the complete lining under the severest operating conditions. NARTAR 7 -- A burned and impregnated 96% MgO brick produced from the same synthetic periclase used in NARTAR PAD. It incorporates proprietary modifications which produce a refractory having the highest density, lowest porosity and highest hot strength available in any product of its class. It is recommended for areas of vessels where hot strength and density are of prime importance.

This complete line is designed for temper atures from 2000F to 3300F. The selection of any one type depends mainly upon the maximum temperature to be encountered in service. All types can be used directly exposed in equipment fired with gas, oil, electricity, or powdered fuel. However, insulating fire brick should not be used where they are exposed to molten metal and slags or severe mechanical abrasion. When these conditions prevail, insulating fire brick should be used as back-up insulation. insulating fire brick improve operation by: 1. Reducing fuel costs 2. Speeding production 3.

To utilize good design, careful attention to refractory construction is required. Such construction is a highly specialized and skilled trade and should be entrusted only to experienced FIRE BRICK masons. To operate efficiently, a furnace wall should be con structed to meet the following somewhat conflicting re quirements as far as is practical: 1. The strongest possible bond or tie across joints and through the wall, 2. A construction as airtight as possible, 3. Provision for removing and rebuilding the inside brick courses on the hot face as easily as possible and with the least disturbance to the rest of the wall and 4. Provision for relieving the fluctuating ex pansion strains by allowing proper expansion joints. The determining factor in meeting the first three re quirements is the type of bond used and the soundness of the brick laying. The type of expansion joint is not de pendent on the kind of bond used. MASONRY BONDS On the opposite page are illustrations of some standard masonry bonds. The wall thickness and type of bond is determined by service conditions present and load due to the height of the wall. To achieve maximum strength plus an airtight or gastight wall, it is important to stag ger vertical joints. The alternate header and stretcher bond is good prac tice and probably the most common. The only reason for departing from such a bond is to reduce the difficulty of repairing some portions of the furnace walls that require attention previous to the remainder of the furnace. Under such circumstances a compromise is advisable using three, four or five headers to one stretcher course, Once the arrangement of headers to stretchers on the furnace face is established, the same cross bond carries systematically through the wall for walls of any thick ness and repeats itself at regular intervals. BRICKWORK CONSTRUCTION (Cont'd) Expansion Joints One of the important considerations in designing and constructing furnaces is that the brickwork expands and contracts due to heating and cooling. Severe fluctuating stresses are often developed as the temperature inside the furnace rises and falls. This is supplemented by the steep temperature gradient usually present in furnaces whereby the hot face expands more than the cooler parts of the brickwork. It should be noted that this expansion takes place both horizontally and vertically. Provision for vertical expansion, except in high walls, is easily made by leaving the wall free to expand upward without encountering boiler drums, piping or other structural members. Vertical contraction during subse quent cooling takes care of itself when the wall settles. There are two common types of expansion joints for horizontal movement as shown on the opposite page. The "Staggered" or "Broken" type has the open joints stag gered at adjoining courses. This type is perhaps simpler and easier to construct as it requires no large 9 inch straights or cutting and fitting. This type also results in a minimum weakening of the wall at the expansion joints. The "Straight" or "Vertical" type with no overlapping headers, allows the wall sections to expand and contract with a greater freedom which results in a minimum of buckling on the inside brick courses. As the ability to open and close easily is the expansion joint's main requisite, the free movement of the "Straight" type probably outweighs any disadvantages. In practice, expansion joints are usually constructed to provide for double the expansion that will occur on the first heating. This allows for any accidental filling of the expansion joints by mortar, dust, or materials charged into the furnace during operation. To keep joints clean, they are usually packed with a combustible or compressible filler during construction. There is a large variety of expansion joints used for corners, joining auxiliary walls and separating zones of different temperatures. Shown are examples that are generally considered good practice. f STRAIGHT OR VERTICAL TYPE AND CORNER JOINT STANDARD SKEWBACKS SKEWS SHUT WITH STANDARD BRICK 2Vi" m for ARCH 4 Vi" THICK Rise 1 */2 n per ft. of span Skew consists of 1-9" 2-Inch Brick 12lA" 1-9" Feacheredge /Series 9" for ARCH 4 Vi" THICK Rise 2^" per ft. of span Skew consists of 1-9" 48 Side Skew |9l/ ,, 2-9" 48 End Skews 1-9" Soap Brick Jbenes 2V* 9` for ARCH 9" THICK Rise 2%$" per ft. of span Skew consists of 2-9" 48 End Skews! 9l/ 2-9" -9" 4S8oaSp idBeriSckkews'-S" e'r9ies SPECIAL SKEWBACKS ARCH 4Vs" THICK Rise 2" per ft. of span ARCH 9" THICK Rise 2" per ft. of span for ARCH 9" THICK Rise 1V2" per ft. of span SPECIAL SKEWBACKS far Arches with Included Angle of 60 Degress 2%" 4VV' for ARCH AVi" THICK Rise 1.608" per ft. of span 13VV' 6Y* for ARCH 13Vi" THICK Rise 1.608// per ft. of span SKEWBACKS IN FURNACES Skewbacks are masonry units with an inclined face from which an arch is sprung. As illustrated, a single special shape may be used, or a combination of standard brick sizes may be laid up to form the skewback. The onepiece skewbacks are stronger and are generally used for arches of longer spans. The important requirements for skewbacks are high strength and good bearing on the sidewalls. The skewback receives the full thrust of the arch which includes a downward thrust exerted by the weight of the arch as well as an outward thrust on the sidewall. Support of the arch is usually made by steelwork consisting of angles or channels on which the skews rest. These angles and channels are held in place by buckstays generally connected by tie-rods with provisions for adjustment as the furnace temperature rises and falls. If structural steel is not used, the sidewall must be constructed to receive the entire thrust of the arch. When steelwork is used, the line of thrust should fall within the channel or angle to promote stability of the arch. Skewbacks should be placed so they are protected as much as possible from the destructive forces of the furnace, a precaution which usually lengthens the life of the skewback. To further protect the skewback, a stretcher course should never be used directly below the skewback. Shown are two commonly used methods which are considered good practice for holding skewbacks. ELEMENTS OF ARCHES KEY TO SYMBOLS f FORMULAS: S - Span ot arch H = Rise of arch R - Outside radius of arch r = Inside radius of arch T = Thickness of arch A - Outer arc length a = Inner arc length 0 - Central Angle To find the rise when the radius and span are given: H = r--1 o \-'4r2=S2~ To find the inside radius when the rise and span are given: S-4-4LT 8H To find the angle (-) when the radius and span are given: S Sine l o W =-------- 2r To find the arc lengths when the radius and central angle are given: Outer arc: Inner arc: 2 T R0 2 7C r 0 rAi =-* a 360 360 VALUES FOR GIVEN RISES PER FOOT OF SPAN Rise in Inches Inside * Ipr Radius is Foot Factor of Span X S Central Angie 0 Degrees Part of Circle Diff. of* Inside* Outer and Arc is Inner Arcs Factor Factor xS XT Skewback X* is Factor xT Y* is Factor xT I l 14 IVI 1.608 04 2 2 Li 2.302 214 231 3 1.5417 1 2521 1.0625 1.0000 0.9301 0,8333 0.7604 0.7474 0.7042 0,6600 0,6230 37*50.9' 47*4.4' 56*8.7' 60*0,0' 63*2.3' "3<344.4' 82*13.4' 8358.5' 90*28.8' 98*29.7' 106TS.6' 0.1051 0.1308 0.1560 0,1667 0,1807 0.2048 0.2284 0.2333 0.2513 0.2736 0.2952 1.0184 1.0287 1.0412 1,0472 1.0558 1.0725 1.0913 1,0954 1,1120 1.1346 1.1591 0.6606 0.8216 0.9799 1.0472 1.1352 1,2870 1.4351 1.4656 1.S792 1.7191 1.8546 0.3243 0.3993 0.4706 0.5000 0.5376 0.6000 0.6575 0,6690 0.7101 0.7575 0.8000 0.9460 0.9168 0.8824 0.8660 0,8432 0.8000 0.7534 0.7433 0,7041 0.6528 0.6000 *Inside radius, inside arc, difference of outer and inner arcs, x and y are obtained by multiplying the factor in each respective column with S or T, whichever applies.

Crossen, Vice President--Sales First Class Permit No. 1 Cleveland, Ohio FOREWORD This pocket-sized booklet is intended to be a handbook for the user of refractories as well as a catalogue. The tables are designed to give complete coverage of ail necessary information for the design and application of refractory materials. They have been thoroughly revised to give a maximum of data with emphasis on clearness and easy usage. This is a workday booklet outlined for convenient reference in solving everyday problems. The refractory products covered are highly diversified. They range from high alumina, basic and silica brick to low duty firebrick. For use in conjunction with these vari ous types of brick, there is offered a complete series of high temperature mortars and ground fire clays. The proper one is available for any type of installation. Simi larly, a wide variety of plastic refractories, castable re fractories and ramming mixes are described. The proper selection of these materials is quite important as service life is often determined as much by the mortar used or the refractory specialties employed as it is by the fire brick. The properties of these materials are tabulated for conciseness and clarity. The products described are backed by ample, proven re sources which insure uniformity and availability for years to come, In each major producing district all of the impor tant manufacturing processes are employed to produce re fractories that will successfully meet the exacting service conditions of present day furnaces. Ail mining and manu facturing procedures are under regular laboratory control to insure the consistent, high quality of NARCO products. NARCO REFRACTORIES for Steel Making Maximum life between reiines Low refractory cost per ton of steel Products tailored to every service need Superior wear resistance higher-cost refractories can cost less...in the long run More expensive energy sources... ever-rising hourly rates for masons... skyrocketing steel-making equipment costs ... the need to increase productivity ... These factors combine to greatly increase your per-ton cost of making and processing steel. Suddenly, refractories that promise greater life expectancy are economically more attractive ... even when they cost slightly more. With refractories that stretch out the time between major rebuilds, you increase productive on-stream time. With refractories that stand up against the physical and metal lurgical punishment of new steel-making processes, you greatly reduce the costly non-productive periods required for patching. NARCO Refractories can be supplied promptly to handle any process in your steel plant. Basic or acid. Blast furnace to continuous caster. Electric furnace to AOD vessel. refractories for A.O.D, vessels In argon-oxygen-decarburization reactors, unique factors cause unusual refractory wear problems. These factors are: thermal shock from temperature variations, oxidation reduction reactions caused by partial oxygen pressures during argon blowing, slag contamination at the hot face, high turbulence during gas injection, low-basicity slags. Plus some unique operating variables inherent in the A.O.D, process. Obviously, the special conditions in the A.O.D, vessel call for special refractories to meet these conditions, A number of NARCO Refractories have been created to deliver maximum refractory life in A.O.D,'s and keep your refractory cost per ton of steel low.

Rebonded fused-grain brick may be required above the tuyeres to balance wear, NARMAG 608 has shown excellent performance in withstanding the stirring action during gas injection, gas-bubble cavitation, variations in chemistry caused by oxygen pressure variations, temper ature fluctuations, and slag/metal chemistry reactions. There are ideal NARCO refractories for each zone,.. vessel liners, hoods, tuyere area, and safety linings. Ask us for recommendations that have been proved in service in nearly all the A.O.D, shops around the country. refractories for electric furnaces in the NARCO line, there are refractories for basic and acid practices in electric furnaces used for making steel. We have developed refractories that have higher resistance to the destructive effects of basic practice. And we have developed refractories to give longer life in today's ultra-high powered electric furnaces. Properties Include better strength at higher temperatures, superior resistance to impact and abrasion, thermal-shock endurance, and low porosity and permeability. Together these properties can keep your electrics on-stream longer between repairs and relining, Increase your yearly tonnage.., improve your operating ratios, and profitability. Differences In zone-by-zone refractory service require ments call for a variety of refractories to work together in meeting ail the conditions. We can supply the most suitable refractory for each area.

For the newer Q-BOP furnaces, we have adapted certain NARCO refractories originally compounded for BOF's. Presently NARCO refractory materials are used in all Q-BOP's in North America. The performance and cost of refractory/ton of steel,of NARCO materials for the BOF's and Q-BOP's are highly satisfactory both technically and costwise to steel makers throughout the Western hemisphere. Two major applications for NARCO refractories in con tinuous casters are the ladle and the tundlsh. NARCO refractories with special characteristics have been developed for the fundisb applications. These refracto ries are compounded to have high resistance to; impact wear from the Sadie outflow, slagging, gassing, and the chemical/ metallurgical effects of special continuous-caster-grade alloys. Ladle linings used with continuous casters are laid up with NARCO high-alumina, expanding-type ladle brick. These bricks have greater resistance to higher tapping temperatures and extended holding times common in this type of service. Their expansion characteristics provide tighter joints and greater freedom from rat-holing, other applications in steel making There are job-proved NARCO Refractories for every spot in the steel plant. In addition to the ones already discussed, NARCO Refractories are used in hot-meiai cars, and other places where minimum downtime, maximum time between scheduled repairs, and low refractory cost to steel tonnage are important. Ladle slide gates and nozzles in chemistries to withstand any combination of chemical attack, erosion, and physical opening and shutting of *he gates are supplied by NARCO, We can provide shapes and sizes to work perfectly with any ladle gating system. Call your NARCO man, or write us for technical advice, specification help, and refractory data. open hearth and Marco Refractories Stepped-up demand for stee! has also stepped up the service requirements for refractories in existing open hearths. And has placed a large premium on longer time between open hearth relining. NARCO Refractories for open hearths can be supplied in a numberof chemistries to give extended life in the bottom, along the slag line and in the roof where gases and highimpingement flames corrode and erode the lining. There are NARCO brick and shapes to expedite relining any type, size, and shape of open hearth. Close control of dimensions assures that NARCO refractories can be laid up at top economic speed. And that the refractories will stay firmly in place for many more heats between shut-downs. Narmag 60DBC Narmag 60DBRC SUBHEARTH Narmag 90B Narmag B NORTH AMERICAN REFRACTORIES CO.

NARCO bricks are especially recommended for their outstanding life under these conditions: Mechanical abuse during charging and skimming, Aggressive fluxes. Reactive alloys and additives, Inter mittent furnace operation. They especially show excellent life and economy in the sidewalls and hearths exposed to molten aluminum. NARCO plastic and castable materials have the rugged properties needed for upper walls and roofs. Their service life, of course, is based on the care used in installation so that a tight and leak proof lining is obtained. Positive anchorage is also a must.

Customized recommendations and drawings will be supplied on request. Refractories for Cupolas Cupolas impose some of the most severe conditions on refractories of any equipment in the foundry. The refractory has to withstand a combination of abrasion, heat, thermal shock, acid or basic slag chemistries and mechanical stress. Added to these are: high-velocity air-blast, spotty air impingement caused by channeling because of non-uniform density of the charge, and variations in tuyere design. h'o one refractory can be the answer to ail these punishing variables in day-to-day foundry operations and materials. NARCO can provide a complete range of refractories developed and proved to work best at each trouble spot.

Energy is scarce. And expensive. At the same time, there Is ever-increasing emphasis by build ers and governments on more predic table, repeatable performance by the cement in producing uniform topgrade concrete. Higher rates for skilled masons make rebricking even more costly. The ratio between refractory cost and labor rates now makes it wise to buy better refrac tories with longer life expectancy, thus reducing labor costs by reducing the number of kiln outages. You are struggling with an unusual combination of operating circum stances . . . keep production up . . . hold maintenance costs down . . . use energy more efficiently . . . reduce un productive downtime . . . make a profit . . . maintain cement quality and uniformity.

We can help you keep your kiln running longer between refractory-related outages. NEW REFRACTORY FROM NARCO... NARMAG 608K-C delivers longer fife in the burning zone. This patented refractory was developed by NARCO research to meet the requirements of Portland cement producers for a basic liner that will provide substantially longer burning zone life. NARMAG 608K-C refractory is 20% less porous than most directbond brick. Its unique combination of properties includes chemical compatability with the kiln feed, produces faster clinker coating formation, improves fuel utilization. This makes the clinker coating more stable; combined with the fact that in most cases, the clinker coating can be removed from the liner with minimum damage to the surface of NARMAG 608K-C refractory. NARMAG 608K-C's 20% lower porosity reduces penetration of the refractory pores by alkalies and sulfides. It also holds thermal dimensional changes to a minimum, resulting in less change in refractory microstructure at elevated process temperatures. (The tend ency of this product to spall during outages is also less than with other basic brick.) Chemical compatibility of NARMAG 608K-C with the feed in the burning zone is excellent. This prevents the development of an overly dense structure in the refractory hot face that can cause undesirable spalling during outages. Higher strengths at refractory operating temperatures greatly improve the structural stability of the refractory at maximum kiln zone temperatures, it also improves the resistance of the refractory to mechanical torsional stresses set up in kilrr and liner during rotation.

Oxidation/reduction at mospheres further complicate the topchecker problem. NARMAG 98 is our 98% MgO chem-bonder refractory de signed for top-checker lay-up. NAR MAG, a 95% MgO grade, can be used. Zone 2: In the middle checker zone, cyclical temperature fluctuations are less severe. Temperatures are normally above a level that can cause condensa tion and deposition of alkali from heat ed kiln gases. Solid carry-overs are low, with less reaction. Oxidation/ reduction reactions are less because of lower temperatures for gases and checkers. Recommended: NARMAG 90 NARMAG 90B NARMAG NARMAG B 90% MgO CHEMBOND 90% MgO BURNED 95% MgO CHEMBOND 95% MgO BURNED Zone 3: in the bottom checker entry, air temperatures can vary widely. Vola tile alkalies in the exhaust gases not caught at the intermediate checker zone can condense here. Dust and spalling from upper-level checkers can cause dust impingement, fragment im pact, and plugging of lower checker- work. Recommended: NARCO 40B 40% MgO BURNED NARCO 40HB 40% MgO HIGH FIRED NARCO 608 60% MgO DIRECT BONDED Also MOHAWK high-fired super-duty firebrick where temperatures are not excessive and sulfate volume is low. Zone 4: Port and Regenerator. At the regenerator crown, upper wall, and target wall areas, the refractory must withstand broad temperature cycling, an oxidation/reduction atmosphere, and attack by carry-over solids. Volatile carry-over is not encountered because of the high temperature. Target walls are' the major area of attack by solid carry-over from the facing ports. Refractory choice depends on opera tion conditions. The higher chromecontent refractories (NARMAG 40HB) have better corrosion resistance. The higher magnesia-content refractories (NARMAG 50DBR) show better per formance under oxidation / reduction atmosphere. Recommended: NARMAG 40HB 40% MgO HIGH FIRED for regenerator crowns. NARMAG 50DBR 50% MgO DIRECT BONDED for upper regenerator and target walls. Zone 5: Rider arches, rider span tile, and adapter courses carry heavy loads and are under severe stresses. They are also subject to alkali attack. A high-fired, super-duty refractory is re quired. Recommended: NARMAG 608 60% DIRECT BONDED. NARCO WO-675 High purity super duty for severest applications. MOHAWK For less severe conditions. Zone 6: Tank Linings. For the melter crown, use a dense, super-duty silica refractory to withstand alkali vapor at tack. These bricks have excellent hightemperature strength, high purity, high density, and excellent resistance to "rat-holing". Recommended: NARSIL silica brick, for severe service. MtU and MtU-R for less severe service. Zone 7: Superstructure. Under normal melting conditions, the remainder of the superstructure can be laid up with dense, super-duty silica brick. They are low in cost and also become an un contaminating ingredient of the glass batch as they melt. Recommended: NARSIL Silica brick. MtU-R Silica brick. Under more severe conditions, a 70% alumina refractory provides most of the advantages of mullite, but at lower cost Recommended: SENECA 70% alumina Volume Stable, Zone 8: Glass Contact. NARCO does not make any zirconia refractories re quired for lining lower sidewalls, bot tom pavers, and other areas in direct contact with the glass.
