Special Mullite Castable for Outlet of Back Kilneye of Cement Kilns
The Description:
Corundum mullite castable is made of brown corundum, white corundum, andalusite, mullite and high quality bauxite as the main raw materials, adding superfine powder refractory powder by scientific formula proportional mixing. Corundum mullite refractory castable contains less mullite in nature, and the industrial mullite raw materials are synthetic, with high purity, relatively large density, good structure, low creep rate, small thermal expansion, good thermal shock resistance and chemical erosion resistance, widely used in refractory materials and other industries. Corundum mullite castable uses high quality refractory raw materials, and the refractory castable produced has good thermal shock resistance.

Characteristics of corundum mullite refractory castable:
It has the common advantages of corundum refractory castable and mullite castable. At high temperature, part of the matrix reacts in-situ to form mullite phase, which improves the high temperature thermal strength and thermal shock stability of the castable lining. It has high compressive strength at high temperature, good thermal shock resistance and structural spalling resistance. Good high temperature volume stability and thermal shock resistance, high softening temperature under load, low creep rate at high temperature, good chemical corrosion resistance
Corundum mullite castable Use: It can be used in petrochemical industry tubular heating furnace, light diesel oil, ethane-cracking furnace lining, atmospheric and vacuum furnace, sulfur recovery device, steam boiler, shell shell insulation layer, two cylinder and pipe insulation single layer, other industrial furnace door, fire viewing hole, observation hole door lining, large power station boiler anti-wear lining, gasifier, circulating fluidized bed boiler lining and cement rotary kiln coal injection pipe and other high temperature kiln With a lining.
