RESPONSE: Admitted. 24. Before 1972, Defendant did not at any time take any action to inform users and/or those exposed to its asbestos-containing products of the existence of a Threshold Limit Value (TLV) for asbestos. RESPONSE: Admitted 25. Defendant did not at any time take any action to inform users and/or those exposed to asbestos-containing products of the recommendations of the 1946 Flcisher Drinker Study in Conclusion 2 from that study that "the operations of hand saw cutting, grinding, cement mixing and installation . . . should be equipped with exhaust ventilation to keep the total dust concentration low. RESPONSE: This Defendant at no time had knowledge of the Fleisher Drinker Study and therefore could not have taken action on any recommendations which may have been set forth in that study. Moreover, that study would appear to pertain to pipecovering and ship building applications which in no way pertain to this Defendant's products or their use. 26. Before 1972, Defendant did not at any time take any action to inform users and/or those exposed to asbestos-containing products of the recommendations of the 1946 Fleisher Drinker Study in Conclusion 2 from that study that "the operations of hand saw cutting, grinding, cement mixing and installation . . . should be equipped with exhaust ventilation to keep the total dust concentration low. RESPONSE: This Defendant at no time had knowledge of the Fleisher Drinker Study and therefore could not have taken action on any recommendations which may have been set forth in that study. Moreover, that study would appear to pertain to pipecovering and ship building applications which in no way pertain to this Defendant's products or their vse 27 Defendant did not at any time take any action to inform users and/or those exposed to asbestos-containing products of the recommendations of the 1946 Fleisher Drinker Study on Page 15 of that study that "the suggestions made relative to exhaust ventilation and respiratory protection are ... of value in maintaining . . . low incidence of asbestos". RESPONSE: This Defendant at no time had knowledge of the Fieisher Drinker Study and therefore could not have taken action on any recommendations which may have been set forth in that study. Moreover, that study would appear to pertain to pipecovering and ship building applications which in no way pertain to this Defendant's products or their use. 28. Before 1972, Defendant did not at any time take any action to inform users and/or those exposed to asbestos-containing products of the recommendations of the 1946 Fieisher Drinker Study on Page 15 of that study that "the suggestions made relative to exhaust ventilation and respiratory protection are ... of value in maintaining . . low incidence of asbestos". RESPONSE: This Defendant at no time had knowledge of the Fieisher Drinker Study and therefore could not have taken action on any recommendations which may have been set forth in that study. Moreover, that study would appear to pertain to pipecovering and ship building applications which in no way pertain to this Defendant's products or their use. 29 Defendant did not take any actions at any time prior to 1972 to inform users and/or those exposed to its asbestos-containing products of either: (a) Suggestions regarding exhaust ventilation when using asbestos products and/or; (b) Suggestions regarding respiratory protection when using asbestos products. RESPONSE: Because North American Refractories Company had no reason to believe its small number of products, designed for use in wet or encapsulated forms, which contained small percentages of asbestos that changed into non-asbestos form as a result of exposure to beat, would in any way require exhaust ventilation and/or respiratory protection, it did not inform anyone of suggestions regarding same. Moreover, this Defendant believed that its large industrial customers were taking whatever respiratory precautions were needed for their workers and workplaces, as was this Defendant. 30. Defendant knows of no test done by it or at its request to determine asbestos dust concentrations resulting from the cutting, handling, application, and use of any asbestos-containing product manufactured or sold by it. RESPONSE: Because North American Refractories Company had no reason to believe its. small number of products, designed for use in wet or encapsulated foims. which contained small percentages of asbestos that changed into non-asbestos form as a result of exposure to heat, could in any way be harmful, it neither performed nor requested tests to determine asbestos dust concentrations. 31. Defendant continued to sell asbestos-containing products after the date on which it claims to have ceased the manufacture of asbestos-containing products. RESPONSE: To the best of North American Refractories Company's knowledge, information and belief, it ceased its sale of products which contained small percentages of asbestos on or about the same time period in which it ceased the manufacture of such products. 32. Defendant never recalled from dealers, users, or distributors any of its asbestos-containing products that had not been used or sold when Defendant claims to have ceased the sale of asbestos-containing products. RESPONSE: Because North American Refractories Company had no reason to believe its small number of products, designed for use in wet or encapsulated forms, which comained small percentages of asbestos that changed into non-asbestos form as a result of exposure to heat could in any way be harmful, it did not recall any products that had not been used or sold. Moreover, this Defendant's products were generally sold to its customers very near in tune to their use. INTERROGATORY DIRECTED TO ALL DEFENDANTS 1.

This defendant has from time to time manufactured, sold and/or distributed refractory products which contained small amounts of asbestos. This defendant never manufactured any refractory product which contained asbestos prior to 1961. This defendant objects to the production of information concerning any facilities or geographic areas where plaintiffs did not work. To do so would require an unreasonable search of this defendant's records, would not lead to relevant information and would cause unreasonable annoyance, oppression, burden and expense to this defendant. This defendant further objects to the production of information concerning any of the facilities involving Shinaberry & Meade or Fields & Maroney plaintiffs inasmuch as this defendant has settled or been dismissed from all of those cases or is not a party. This defendant also objects to providing information concerning facilities which are not identified by specific location. Without waiving these objections, this defendant is reviewing its records for sales to the numerous sites listed on Exhibit "A". Below are the results of this defendants' investigation to date. Information on additional sites will be provided as it becomes available. -1- facilities: North American Refractories Company made no sales to the following Albright PS Alcon Rolled Products, Fairmont, WV Analine Chemical, Charleston Armory, National Guard Atomic Energy Plant, Waverly Bank, Parkersburg National Beaver Valley #1 PS Beverly PS - Muskingum River Borg Wamer/Marbon, Parkersburg, WV/Washington, WV Bruce Mansfield PS Burger PS Brilliant PS, Brilliant, OH Centre Foundry, Wheeling, WV College, Bethany College, Concord Dillies Bottom PS, Dillies Bottom, OH RE Berger PS, Dillies Bottom, OH Harglo Glass Harrison PS, Masontown, PA Hatfield's Ferry PS Hospital, Elkins Hospital, Fairmont General Hospital, Monongalia General -2- Hospital, St. Joseph's Parkersburg Hospital, St. Marys Hospital, WVU Medical Center Hospital, Wheeling Koppers, Follansbee, 9 Koppers, Bridgeville, PA Mall Ohio Valley/St. Clairsville Master Glass Company Mine Academy, Beckley Mobay-Natruim, WV Muskingum River a/k/a Beverly PS Plastic Coating, Inc.

See answer and objection to Interrogatory Number 1. To the extent this Interrogatory requests information beyond the asbestos-containing products this defendant sold or supplied to the specific facilities at which plaintiffs worked, it is objected to as irrelevant, beyond the scope of relevant discovery and unduly burdensome and oppressive. Investigation is still continuing and this Interrogatory will be supplemented as further information becomes available. 3. See answer and objection to Interrogatory Number 2. Without waiving these objections, this defendant has manufactured numerous refractory products which did not contain asbestos. See product catalog attached as Exhibit "A". Since none of the plaintiffs allege other than asbestos-related disease, to further answer this Interrogatory would require an unreasonable search of this defendant's records, would not lead to relevant information and would cause unreasonable annoyance, oppression, burden and expense to this defendant. -4- at r- 4. North American Refractories Company did distribute two products manufactured by Eagle-Picher. See answer to Interrogatory No. 5. 5. This defendant had a relabeling agreement from 1957 until 1971 with ^Eagle-Picher to distribute their Super "66" insulating cement as our product under the name (^Stazon^ement and their One-Cote cement as our product under the nam^Unicote^Cement. This defendant is unaware of any other relabeling agreement. 6. See answer and objection to Interrogatory No. 1. 7. See answer and objection to Interrogatory No. 1. 8. The only distributor located within the cities or counties listed in Interrogatory Number 8 is the H. R. Curry Company located at 1023 Main Street in Pittsburgh, PA. Attached are orders evidencing sales of Narco Staz-On Cement to the H. R. Curry Company dated 2/25/71, 3/30/71, 4/16/71, 5/4/71, 7/20/71 and 10/1/71. Narco Staz-On Cement contained asbestos until some time in 1971. Since this product was manufactured by Eagle-Picher and not by Narco, this defendant is unable to establish exactly when in 1971 asbestos was removed from Staz-On. Therefore, Narco is unable to determine if the Staz-On product sales, all of which took place in 1971, contained asbestos. 9. See Answer to Interrogatory No. 8. 10. This defendant sold no asbestos-containing products to any distributor in the State of West Virginia. 11. N/A. See Answer to Interrogatory No. 10. 12. No. -5- NORTH AMERICAN REFRACTORIES COMPANY'S ANSWER TO REQUEST FOR PRODUCTION OF DOCUMENTS 1. This defendant objects to the production of all records that show sales, receipt, use, re-sold, distribution, inventory, re-order, shipment, bill of lading or orders of asbestos-containing products to any facilities or geographic areas where plaintiffs did not work. To do so would require an unreasonable search of this defendant's records, would not lead to relevant information and would cause unreasonable annoyance, oppression, burden and expense to this defendant. This defendant further objects to the production of records that show sales, etc. of asbestos-containing products to any of the facilities involving Shinabeny & Meade or Fields & Maroney plaintiffs inasmuch as this defendant has settled or been dismissed from all of these cases or is not a party. This defendant also objects to providing records concerning facilities which are not identified by specific location. Without waiving these objections, this defendant is reviewing its records for sales to the numerous sites listed on Exhibit "A" and the cities and counties listed in Interrogatory Number 8. Attached as Exhibit "B" are the invoices representing sales of products to H. R. Curry Company which may have contained asbestos. Investigation is continuing. Other records will be produced as further information becomes available. ROBINSON & McELWEE BY: Attorneys for North American Refractories Company, One of the Defendants -6- VERIFICATION Jay S.

Cmida ) FOREWORD This pocket sued booklet is intended to be a handbook lor the user ol refractories as well as a catalogue. The tables are designed to give complete coverage ol all necessary information lor the design and application ol refractory materials. They have been thoroughly revised to give a maximum ol data with emphasis on clearness and easy usage. This is a workday booklet outlined lor convenient reference in solving everyday problems. The refractory products covered are highly diversified. They range Irom high alumina, basic and silica brick to low duly firebrick. For use in conjunction with these vari ous types ol brick, there is offered a complete series ol high temperature mortars and ground lire clays. The proper one is available lor any type ol installation. Simi larly. a wide variety ol plastic refractories, castable re Iraclories and ramming mixes are described. The proper selection ol these materials is quite important as service lile is olten determined as much by the mortar used or the refractory specialties employed as it is by the lirebnck. The properties ol these materials are tabulated lor conciseness and clarity. The products described are backed by ample, proven re sources which insure uniformity and availability for years lo come. In each major producing district all of the impor lant manufacturing processes are employed to produce re fractories that will successfully meet the exacting service conditions ol present day lurnaces. All mining and manu facturing procedures are under regular laboratory control lo insure the consistent, high quality of NARCO products. GUARANTEES NARCO uses extreme care throughout every phase of production and distribution of its refractories in order to furnish only high quality materials which in its judgment are best suited for the purposes for which they are intended. The consumer will find it advantageous to seek and select the material which will give him the best results and to exercise care and discretion in the use of the ma terial which he receives. In the sale of refractories, no performance guarantees are made, since the manufacturer has no control over the manner ol installation or conditions to which his products are subjected in service. SIZE DEVIATIONS When tested in accordance with Standard Method C-134 of the American Society for Testing Materials, nine-inch brick shall not show a site variation of more than plus or minus two per cent.

References shown in this manual should be given to facilitate expediting orders for palletizing shipments TYPES OF FIRECLAY BRICK Fireclay brick are (he industry's most important product because their wide range ol properties fils them lor use in a great variety ol refractory applications. NARCO fireclay brick plants and mines are located in Pennsylvania. Ohio, Ken tucky and Missouri where a wide variety of high-grade (lint, semi-flint ahd plastic bond clays are available in Ihe 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 ol 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 slag 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. SUPER DUTY FIRECLAY BRICK Increased severity of service conditions in many modern furnaces has made it more economical to use super duty refractories rather than even the best high duty brick. 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 duly brick offer Ihe 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 ol lower quality brick, (c) cost ol 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. Ihe 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- SUPER OUTY FIRECLAY BRICK (Cont'd) cellent 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 duly 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 ol the high quality of this product. These records have been compiled through many years ol continued use by satisfied customers. HIGH FIRED SUPER DUTY FIRECLAY BRICK MOHAWK and MOHAWK BF are high fired super duly dry press firebrick compounded from Missouri materials and similar in chemical composition to NARCO 68. Spe cial heat treatment through extremely high temperature bring produces a strong, lough product of low porosity and stability ol volume al working temperalures. The desirable properties of hot load bearing strength, resist ance to lluid slags and metals, stability under soaking heat and resistance to abrasion and carbon monoxide disintegration assures longer hie in lurnace structures operated under the most severe conditions. MOHAWK high bred super duly 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 ol these properties MOHAWK is particularly suited lor bottom blocks and upper stack areas ol blast furnaces which are exposed to severe abra sion by the lurnace charge These characteristics also make MOHAWK ideally suited for many other applications as glass lank checkers and rider tile, torpedo type iron ladles, hot metal mixers, non ferrous furnaces and vari ous vertical and rolary kilns. MOHAWK BF high bred super duly brick is fired at a temperature slightly less than MOHAWK lo provide greater spalling resistance and still maintain a desirable balance ol physical properties MOHAWK BF is particularly suited for the lower slack areas of blast furnaces, forge fur naces, billet and slab furnaces, reheat furnaces and other lurnace applications where temperature fluctuations are encountered. HIGH DUTY FIRECLAY BRICK NARCO produces brick ol high duly quality in all the major producing districts,thus enabling the lurnace oper ator to obtain just the brick lor his needs, in a minimum amount possible otfh.rtoimugeha nt'hdeatscaiemntiinficimucmomcboinsitngto him This is ol numerous types of clay and variations in the processing methods whereby a series ol brands is produced in each district pos sessing a range ol physical properties to combat various combinations ol destructive lorces 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 lurnace while in another part ol the same furnace slag penetration may be dominant. Proper selec tion ol the various types of high duly refractories can ma terially lengthen the service lile 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 ol close cooperation with the users of lire 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 fhe inter mediate or tow duty class give excellent service. They are strong, lough, dense and are especially resistant to abra sion and slag action at moderate temperatures. Thus they Imd use in cooler sections ol boilers, upper parts ol cupolas, cooler sections of both vertical and rotary lime kilns and podland cement kilns, healing and annealing furnaces and many similar lurnaces 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 all 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 ol furnaces, kilns and chimneys exposed to the weather. In many industrial furnaces, operating temperatures ollen 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 lile of the refractories. NARCO HIGH ALUMINA BRICK REFRACTORIES (Cont'd) NARCAL 75 C NARCAl 75 C is a 75% alumina phosphate bonded brick II has high slrenglh and load bearing ability, and excellent resistance lo abrasion, erosion and mechanical abuse.

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 Ihe latest technological developments and the most modern manufacturing equipment applied to basic raw materials of the highest purity. Use ol 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 all basic compositions required (magnesite, magnesitechrome, chrome-magnesite and chrome). These varied basic compositions are available both burned or chemically bonded, plain, melaijencased or internally plated, enabling the selection of a basic brick with the proper chemical and physical properties lor the specific requirements ol the application. I DIRECT BONDED BASIC REFRACTORIES Direct bonded basic brick are characterized by Ihe predom malice ol direct attachment ol periclase lo periclase or periclase lo chrome grains in the brick structure. Such refractories are produced Irom carefully selected raw materi al lo achieve desired chemistries and incorporate extremely high bring temperatures lo develop proper physical proper ties. The brands range in qualities Irom 50 lo 96% MgO and display one or more ol such benefits as improved slag resistance, lower porosity, greater density and outstanding hoi strength properties. NARMAG 50DB - a direct bonded magnesile chrome brick ol approximately 50% MgO content. For use in copper and copper nickel service, AOD vessels, and glass furnaces. NARMAG 60 DB - a direct banded magnesile chrome brick ol approximately 60% MgO content. Displays high hoi strength and refractoriness lor applications as electric lur nace and open hearth walls, mineral processing kilns, glass furnaces as well as non ferrous lurnaces. NARMAG 60DBR -- a direct bonded magnesile chrome brick of 60% MgO content II is recommended lor open hearth roots and other applications requiring good re sistance lo "redox" (reducing - oxidizing) reactions Such reactions often cause destructive growth or expansion problems with conventional grades ol brick. NARMAG 608 -- a direct bonded magnesile-chrome brick ol 60% MgO content displaying lowest porosity and highest density for its class Especially recommended for use under severe slagging conditions as encountered in electric lurnaces and AOD vessels. For use in burning zones ol cement kilns. Protected by U.S. Patent No. 3,715.223. NARMAG 80 DB - a direct bonded magnesile-chrome brick in Ihe 80% MgO class The high refractoriness, greater thermal shock resistance, and excellent resistance lo iron bearing slags provides an outstanding product lor specific high temperature applications. SUPER NARMAG B - a direct bonded straight magnesile brick ol approximately 96% MgO content. The high hot stiength and excellent spalling resistance ol this brick makes it particularly suited to glass furnace, rotary lime kiln and other applications requiring a chrome tree product. BASIC REFRACTORIES FOR BASIC OXYGEN FURNACES The advent ol Ihe basic oxygen lurnace(BOF) placed new and enormous demands on relraclory requirements This steel making process consumes huge amounts of substantially pure oxygen to convert hot metal and scrap to steel wiih a high degreeol thermal and chemicrfl efficiency This accomplishment has imposed a number ol severe conditions to the refractory lining. High operating temperatures, severe impact and abrasion, wide temperature fluxualions, operating atmospheres ol reducing and high iron oxide nature together with active slag conditions have dictated Ihe need lor a range ol pitch bearing types of basic refractories. NARCO has played an active role in developing BOF refractories to meet Ihe needs ol Ihe basic oxygen process. The NARTAR series includes conventional (unburned) and tempered pitch bonded varieties as well as burned pilch impregnated grades. The combining ol these materials in basic oxygen furnace working linings enables balance lining wear which results in lower refractory cost per ton ol steel produced. Pilch-Bonded Refractories SUPER NARTAR A--A pitch bonded 96% MgOrelractory brick produced Irom high density synthetic periclase It may be used in any area ol Ihe vessel where an un- tempered brick is suitable.

II bonds brickwork securely Irom normal room temperature to 3000* F and is recommended lor laying lireclay. super-duty lireclay, high alumina and insulating firebrick. It is com posed of the highest grade clays and calcines which enable it to withstand high temperatures without shrinking, cracking, soft ening or overfiring. Comparatively thick joints may be used without difficulty because of these prop erties. It is designed to meet severe service conditions, combat spalling, hold a wall in place under extreme temperature conditions, keep |olnts tight, hold heat in and cold air out. NARCOSET is shipped In all-metal, air tight 15 pound pails and 50, 100, or 200 pound drums. ALSET (Wat) is an air-setting high temperature bonding mortar which is shipped in wet form. It has been formu lated to eliminate all problems arising from shrinkage. The raw materials used in ALSET (Wet) balance each other to yield a product which is stable from the drying-out point to the tem perature limit of the brickwork. This gives a solid uniform bond completely across the lace of the brick in the wall.

ANCHORS and HANGERS FOR MONOLITHIC CONSTRUCTION The following pages show various types ol anchors and accessories ollered by NARCO and illustrate a number of practical methods lor anchoring and suspending plastic or castable refractories in monolithic fuyftace linings. The simplicity of design in NARCO anchors provides vari ous combinations of metal and refractory anchor assemblies adaptable to a wide variety ol applications in construction of furnace linings and heat enclosures. Selection ol anchors should be determined by service conditions and temperature gradients encountered through the walls or root Components of the anchor assembly must be of correct type to meet these varying conditions. TEMPERATURE CONSIDERATIONS IN ANCHOR SELECTION 1. Mild steel parts may be used up to 500*F. 2. Cast iron with 1% cbrome up to 1000*F. 3 Alloys ol 25 12 chrome nickel up to 1550*F. 4. Super duty refractory anchors are recommended at higher temperatures to 3200*F. The drawings indicate the use of higher temperature resistant parts toward the hot face with adequate lower temperature components in the cooler section of the anchor assemblies. CONCLUSION It is extremely important to properly space all NARCO anchor and hanger units to suit design requirements. In general, for wall construction, metal or refraclory anchors should be spaced approximately 15 to 18 inch centers. However, under extreme conditions of temperature and excess vibration, 12 inch centers are recommended. For flat arch or roof construction, NARCO anchors or hangers are usually spaced on 12 inch centers to suit most service conditions. A supply of the NARCO refractory anchor and hanger assemblies illustrated is maintained with adequate stocks of plastics, castables, and refractory gun mixes for prompt shipment. For additional information pertaining to product recom mendations and application methods of anchoring systems described herein, consult the Cleveland Office. METAL ANCHORS AND ACCESSORIES FOR MONOUIHIC CONSTRUCTION METAL ANCHORS AND ACCESSORIES FOR MONOLITHIC CONSTRUCTION MTI-IU MM MAI Mi HIM tOM HMIH1 TW1 AmtCAiioN or nr sibiis bihi boo ahchobs rOB CASIABlt IHSIAUAIIOHS AmiCAIlOH Of ir- SIBIIS BfHI BOO AHCHOBS.

BRICKWORK CONSTRUCTION Furnuce structures requiring a refractory lining are designed and contlrucled for tlie moil efficient service. 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 A. 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. MAiomr 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 gaslight wall, it is important to stag ger vertical joints. The alternate header and stretcher bond is good prac tice and probably the moat 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. TYPICAL MASONRY BONDS 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 arc 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. TYPICAL EXPANSION JOINTS IUMMI Of M UIIIIU) wtll MR COIHII IOIMI STANDARD SKEWBACKS SKIWS lUIlt WIIH STANDARD MICK aw MCM 4'/," VHICK Rite I'/j* pet ft. of tpnn Skew consists of 19* 2 Inch Brick IT'/j" 19' FcathcredfC (Series !

As illustrated, a single special shape may be used, or a combination of standard brick sites may be laid up to form the skewback. The onepiece skcwbacks 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 buckslays generally connected by lie 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.

With refractories that aland 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 lurnace to continuous caster. Electric furnace to AOO vessel. refractories for electric furnaces In the NARCO line, there are refractories for basic and acid practices in electric furnaces used lor making steel. We have developed refractories that have higher resistance to the destructive etlects 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 prolitabilily. Differences in zone-by-zone refractory service require ments call for a variety of refractories to work together in meeting all the conditions. We can supply the most suitable refractory for each area. ROOF Narcal 700 Narcal 85B Ramal 85 Narcotab SIDEWALLS Narmag 608C Narmag 60DBC Narmag 60DBRC SLAQLINE Narmag B Narmag 608 .

These factors are: thermal shock from temperature variations, oxidation reduction reactions caused by partial oxygen pressures during argon blowing, slag contamination at the hot lace, high turbulence during gas ln|ecllon, low-basicity slags. Plus some unique operating variables Inherent in the A.O.O. process. Obviously, the special conditions in the A.O.D. vessel call ` ' lor special relractories to meet these conditions. A number of NARCO Relractories have been created to deliver maximum relractory tile in A.O.D.'s and keep your relractory cost per ton ol steel low. , *.... %. is ?, CONE Naimag 600B WORKING LINING Narmag 608 TUYERE ZONE Narmag 608 Rebonded Fused Grain BOTTOM Narmag 608 SAFETY LINING Narmag 30B Narmag 608 SEALS Narcal BOP (plastic) NARCO low-porosity 60% MgO direct bonded brick (NARMAG 608) with an accessory phase ol dicalclum silicate has proved highly fatlsfaclory lor use in most areas ol A.O.D.'s operating In this country. Rebonded lused-grain brick may be required above the tuyeres to balance wear. NARMAG 60B 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 relractories lor each zone... vessel liners, hoods, tuyere area, and safety linings. Ask us lor recommendations that have been proved in service in nearly all the A.O.D. shops around the country. I 1 11, NARCO has developed a complete (amity ol relractories to meet the special needs and tougher environment ol the BOF. We have also accelerated our production and delivery ol these special refractories lo make Ihe most of Ihe shorter downtime periods required lor relining a BOF.

NARCO shapes are true lo size and Iree Irom warped surlaces to simplify lay up and deliver maximum service on extended BOF schedules. 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 relractory/ton of sleel.of NARCO materials lor the BOF's and Q-BOP's are highly satisfactory both technically and coslwise lo sleel makers throughout Ihe Western hemisphere. Two major applications lor NARCO refractories In con tinuous casters are the ladle and Ihe tundlsh. NARCO relractories with special characteristics have been developed for Ihe tundlsh applications. These refracto ries are compounded to have high resistance to: Impact wear Irom the ladle oulllow, slagging, gassing, and the chemical/ metallurgical ellecls ol special continuous-caster-grade alloys. Ladle linings used with continuous casters are laid up with NARCO hlgh-alumlna, expandlng-type ladle brick. These bricks have greater resistance to higher tapping temperatures and extended holding limes common In this type ol service. Their expansion characteristics provide tighter |olnts and greater freedom from rat-holing. There are |ob-proved NARCO Refractories for every spot In Ihe sleel plant. In addition to the ones already discussed, NARCO Refractories are used In hot-melal 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 ol the 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 tefractory data. refractories for blast furnaces Demands lor greater blast furnace availability and a decision by many sleel makers to eliminate stand-by lurnace capacity have greatly increased the importance ol topquality refractories that will stay on Ihe |ob longer. NARCO researchers have developed improved grades ol refractories to meet your demands. To help your masons lay tighter boltoms and walls, we can supply NARCO brick of all grades true to size and tree from warpage STOCKLINE Mohawk BF Father BF Narcal 606 UPPER INWALL Farber BF Mohawk BF LOWER INWALL Farbar BF Mohawk BF Narcal 606 Narcal 6061 BOSH Mohawk BF Narcal 606 Narcal 6061 BOTTOM Mohawk Farbar BF GUN REPAIRS Narco Blast Furnace Casiable Our NARCO line contains a full range of relractories to operate longer, minimize wear In all blast furnace zones under greatly extended operation peri ods, and reduce your refractory cost per ton of steel.
