In the high temperature state, the anti-crust refractory castable forms a glaze layer on the surface of the material, preventing the penetration of the glass phase in the cement raw material, thereby playing an anti-skinning effect.
The appropriative fireproof castable for kiln door is a high-performance castable developed according to the working conditions of the rotary kiln. Appropriative refractory castable for kiln door has good performance of volume stability, high strength, good wear resistance, thermal shock resistance, corrosion resistance，anti-stripping when using.
The appropriative refractory castable for coal-injection duct is based on the characteristics of materials such as andalusite, corundum-mullite, composite material, and differential combination of activated aluminum powder.
