Corundum mullite castable uses high-quality mullite clinker as the main raw material, uses corundum fine powder as the matrix, and adds additives, admixtures and other auxiliary materials to make the castable construction refractory castable.
Corundum Mullite Castable Advantage
- High operating temperature;
- High temperature strength, good volume stability;
- Strong resistance to chemical and acid erosion;
- Good thermal shock resistance and peeling resistance;
- Excellent thermal shock resistance;
- High-temperature creep decreases.

Corundum mullite castable can be used for anti-wear lining of large power station boilers and lining of other high-temperature kilns. Large cement kiln before and after the kiln mouth, coal injection pipe and other industrial kiln lining and other parts.
This series of refractory castable has the common advantage of corundum castable and mullite castable. High strength at high temperature, good thermal shock resistance and structure spalling resistance, excellent thermal shock resistance, high softening temperature under load, low creep rate at high temperature, good chemical corrosion resistance. It is widely used in large power plant boiler anti-wear lining and other high temperature kiln lining.
