SUL/ATI ON J-M INSULATING FIRE BRICK | DESCRIPTION: Johns-Manville produces six types of Insulating Fire Brick to provide opera tors and builders of high temperature equipment six opportunities to get the one insulating Ere brick that's right for a given service. Each type of J-M Insulating Fire Brick has the correct balance of thermal and physical properties for its recommended service. All six types ofEer light weight, low conductivity and high structural strength. Made from high quality refractory clays (plus alumina in the case of JM-3000), insulating fire brick contain a carefully graded organic filler which is burned out during manufacture to give a uniform, controlled pore structure. AVAILABLE TYPES: JM-3000*--for temperatures to 3000F exposed. JM-28--for temperatures to 2800F exposed. JM-26--for temperatures to 2600F exposed. JM-23--for temperatures to 2300F exposed. JM-20--for temperatures to 2000F exposed. JM-1620--for temperatures to 1600F exposed; to 2000F back-up. 'JM-3000 Iniulttlni Fir* Brick I* tfi* nw*st of th* ill type*. It provides lonf-iift insulation at a full 3000F, in pact-up or direct aaposur* tame*, and is molded tram ipacialiy saiactad kaolin clays plus alumina. USES: Recommended for use as refractory lining or as back-up insulation behind other refrac tory protection in kilns, furnaces, flues, refining ves sels, regenerators, gas producers and mains, soaking pits, stress-relieving furnaces, reactor chambers and similar high temperature industrial equipment. ADVANTAGES High Insulating Value The light weight and high insulating value of J-M In sulating Fire Brick make possible thinner furnace walls, improved efficiency and lower operating costs. Quick Heat Up Furnaces can be brought up to operating temperatures with unusual speed, resulting in increased production. J-M SIL-O-CEL INSULATING BRICK DESCRIPTION: Made from diatomaceous silica, a material composed of millions of micro scopic cells that offer maximum resistance to heat flow, Sil-O-Cel Insulating Brick are particularly useful where high load-bearing characteristics are required. Sil-O-Cel Insulating Brick are furnished in three types for use as back-up insulation behind refractory Are brick linings or behind insulating Are brick linings. The new Sil-O-Cel 16L brick may also be used for exposed as well as back-up service. AVAILABLE TYPES: Sil-O-Cel Insulating Brick are furnished in three different types as follows: Sil-O-Cel Super--for temperatures to 2500F back up only. Sil-O-Cel C-22--for temperatures to 2000F back up only. Sil-O-Cel 16L--for temperatures to 1600F back up or exposed. USES: Sil-O-Cel Insulating Brick are recom mended for use as back-up insulation in furnaces, kilns, hot blast stoves, soaking pits, boiler walls, oil heaters, regenerators, and similar high temperature equipment in the steel, chemical, ceramic, power, petroleum and glass industries. ADVANTAGES Good Insulating Value Used as back-up insulation. Sil-O-Cel Insulating Brick make it possible to reduce the necessary thickness of the exposed refractory as much as one-third. This re sults in substantial savings in furnace wall construction for all the types of high temperature equipment for which these brick are recommended. High Load Bearing Strength Sil-O-Cel Insulating Brick are made from diatomaceous silica, a natural fossilized material which imparts to the finished brick great strength. The Sil-O-Cel C-22 brick, for example, has a cold crushing strength of 700 lbs per square inch. 36 4. 38 AVAILABLE TYPES: 3X Firecrete -- For service to 3000F. Composed principally of high aluminous materials calcined at high temperatures. Recommended for casting thick* nesses of 2 inches or more. H.T. Firecrete--For service to 2800F. Recom mended for casting thicknesses 2 inches or more. Standard Firecrete--For service to 2500F. Devel ops exceptional strength on air curing. Can be used to cast thicknesses as thin as 1 inch. L.W. Firecrete--A light weight, insulating refrac tory concrete for service to 2400F. 75 lbs of dry material required for one cubic foot. CA Insulating Firecrete--A light weight, low iron content refractory for use in controlled atmos pheres. For service to 2600F. No. 20 Firecrete--Similar to L.W. Firecrete but lighter. 58 lbs of dry material required for one cubic foot. Service to 2200F. C-31 M Refractory Cement--A chrome base castable refractory for service to 3000F. H USES: Firecrete is used extensively for mono lithic furnaces and linings and is recommended for such special shapes as those required for burner rings, baffle tile, header protection tile, pipe linings, furnace bottoms and similar installations. ADVANTAGES Hardens Rapidly Firecrete permits casting and use of any desired shape within 24 hours. Resists Spalling All seven types are highly resistant to spalling. Negligible Shrinkage Firecrete has no drying shrinkage and only negligible fire shrinkage at recommended temperatures. Easy and Economical to Use The adaptability of Firecrete makes possible the easy construction of monolithic furnaces, linings and the like which would otherwise require the use of special shapes or involve costly cutung and fitting of brick. TEMPERATUr V ri'J 1 L1. g type: Gunning-Troweling temp limit: 3000F J-M hydraulic setting refractory cement D DESCRIPTION: Four types of dry mono lithic, hydraulic setting refractory cements have been developed and produced by Johns-Manville for gunning and slap-troweling applications. These four refractories are especially adaptable for gun application in building new refractory linings and repairing old ones. They adhere readily with a minimum of loss when "shot" in place. Mixed with water at the gun nozzle, they are pneumatically projected with great force, resulting in a dense, homogeneous lining. Blazecrete is equally effective for heavy patching by troweling, especially where brickwork has eroded deeply. It eliminates the laborious ramming or tamping required with "plastics," and patches need not be preffred. 40 AVAILABLE TYPES: 3X Blazecrete--For service to 3000F. High alumi na content. Particularly adaptable for gun applica tors and for heavy patching by slap-troweling. Standard Blazecrete--For service to 2400F. Alu mina silicate base. L.W. Blazecrete--For service to 2000F. Light weight, alumina silicate base refractory. Used ex tensively for stack linings, heaters and other appli cations where gunning mix with low rebound loss is required. C-2 Refractory Cement--For service to 2300F. Used to advantage in making a protective abrasionresistant refractory surface over L.W. Blazecrete. USES: Recommended for lining or patching forge furnaces, ashpits, cyclones, heaters, boilers, oil refining equipment, furnace bottoms, ladles and similar applications. L.W. Blazecrete is extensively used on tanks, structural steel and skirts for fire protection purposes. ADVANTAGES Hardens Rapidly Applications ready for use within 24 hours of gunning or slap-troweling. Resists Spalling All four types are highly resistant to spalling. Easy to Use Can be applied by gunning or slap-troweling.
