Corundum mullite castables (also called corundum mullite refractory castables) are popular refractory castables for furnace application in the lining of significant power station boiler wear linings and other high-temperature furnaces. Corundum mullite castables have good properties of high-temperature endurable ability, good thermal shock resistance and structural peeling resistance, good thermal shock resistance, high softening temperature, low creep rate, and good chemical corrosion resistance, etc.
Corundum mullite castables’ raw material has brown corundum, white corundum, andalusite, mullite, and high quality bauxite with a specific ratio of ultrafine powder. In industry, mullite is usually artificially synthesized with high purity, dense structure, low creep rate, strong erosion resistance, and well thermal shock resistance.
Corundum mullite castables can perform high properties such as high crushing strength, high-temperature stability, thermal shock resistance, and wear and chemical erosion resistance in the lining of large power station boilers and other high-temperature equipment.
Corundum mullite castables are divided into several grades, products with Al2O3 ≥ 90% based on the corundum phase, products with Al2O3 ≥ 80% based on the corundum phase and mullite phase, and products with Al2O3 ≥ 50% based on the mullite phase. Because corundum mullite castables have the following superior properties in the process of high-temperature use: high-temperature strength, good density modification, good overall structural integrity at high temperatures, good wear resistance, and erosion resistance, It has strong slag corrosion resistance, acid, and alkali corrosion resistance, peeling resistance and no pollution, so it is widely used in electric furnace roof, ladle, garbage incinerator, petrochemical furnace, cement kiln, etc., with good application effect.
