Corundum Mullite Plate
This kind of kiln furniture is kind of Composite Material which utilize fully of the high strength, high abrasion of Corundum phase and high Creep resistance, high thermal shock resistance of Mullite phase. The material can serve in the temp. of 1700℃. Because of the high purity of materials, no volatile matter, it will not contaminate the loading products. Comparing with material from our competitors, our materials will not deform, crack during service which is insured by strict quality control.
Use of white corundum mullite brick
white corundum mullite brick can be directly exposed to flame, peel off, and high temperature resistance. They can be used as heat insulation linings for high-temperature industrial furnaces and working layers for other industrial high-temperature furnaces. They are mainly used in petrochemical industry and large and medium-sized synthetic ammonia gasification. Furnace and magnetic materials, gas furnace materials, high-temperature industrial furnace supporting facilities materials.
