摘要： A high temperature refractory brick wall is repaired by removing and replacing damaged brick while the wall is maintained at a temperature below normal operating temperature but sufficiently high to avoid damage from contraction resulting from cooling. New brick having a coefficient of thermal expansion compatible with the heated wall are used to avoid cracking of the wall due to expansion during heat-up. Workers wearing protective clothing, preferably incorporating a circulating fluid cooling system, remove the damaged brick and install new brick in their place in walls having surface temperatures of about 500.degree. F. or higher and internal temperatures substantially above 500.degree. F., preferably at least about 1500.degree. F.

摘要： Large size cast monolithic refractory repair modules which may be used to replace existing silica bricks within a coke oven heating wall. The modules are formed from a castable refractory mix having very high dimensional stability over a wide range of temperatures. Each of the modules is a rectangular parallelepiped having one or more vertically extending flues formed therein, one end of a module being adapted to conform to the end shape of the damaged heating wall, the other end of the module being adapted to interfit with existing brickwork. The modules are assembled by initially removing damaged brickwork from the heating wall and then placing in the new modules of this invention which are mortared in place. The large size cast modules of the invention are manufactured by selecting a material which when cast will have the desired characteristics, mixing the dry refractory material with a relatively small amount of water, pouring it into a mold on a shaker table and vibrating the mold when filled, and then by firing the cast material after initial set at progressively higher temperatures up to 800 degrees Fahrenheit over a period of almost 60 hours. In addition, novel interfitting modules having specific shapes and sizes may be used for the repairs of ceilings above the coke chambers defined by adjacent heating walls.

摘要： A reconstruction of a heating wall of a coking oven. The reconstruction includes utilization of a novel large size cast refractory repair module which may be utilized to replace existing silica bricks within a coke oven heating wall. The novel large size cast refractory module are monolithic structures formed from a castable refractory material having very high dimensional stability over a wide range of temperatures. Each repair module is a rectangular parallelepiped having one or more vertically extending flues formed therein, one end of a module being adapted to conform to the end shape of the damaged heating wall, the other end of the module being adapted to interfit with existing brickwork. The modules are assembled by initially removing damaged brickwork from the heating wall and then placing in the new modules which are mortared in place. The large size cast modules of the invention are manufactured by selecting a material which when cast will have the desired characteristics, mixing the dry refractory material with a relatively small amount of water, pouring it into a mold on a shaker table and vibrating the mold when filled, and then by firing the cast material after initial set at progressively higher temperatures up to 800 degrees Fahrenheit over a period of almost 60 hours.
