Corundum Mullite Brick
Corundum mullite brick use plate corundum and high-purity fused corundum as the main raw materials, apply advanced ultra-fine powder addition technology, and are fired at high temperature in a shuttle kiln after mixing, forming, and drying. Mainly used in high-air temperature hot blast stove, also used in glass melting furnace and as ceramic burning kiln.
1.Great corrosion and erosion resistance
2.Long service life
3.High compressive strength
4.Good thermal shock resistance
5.Good corrosion resistances to acids and alkali
6.Lower creep rate in high temp
Corundum Mullite Brick Description
Corundum mullite brick are made of high-purity or relatively pure raw materials. It is a high-alumina refractory product composed of corundum and mullite main crystal phases. The presence of low-melting oxide impurities will reduce its high temperature performance. It has good high temperature strength, high temperature creep resistance, thermal shock resistance and erosion resistance.
The Application of Corundum Mullite Brick
Corundum mullite brick used for the key parts of the industrial furnace of steel, electronics, petrochemical, fertilizers, non-ferrous metals, refractory material, etc.
Corundum mullite bricks used in high-temperature sintering of zirconia ceramics, electronic ceramics, magnetic, ceramic powders, carbon black reaction furnaces, etc.
Corundum mullite brick is widely used in decomposition zone and preheating zone of dry cement kiln, high wear parts of grate cooler and other parts scoured by rapid wind.
