Silicon Carbide Castable are made from high-grade silicon carbide and industrial silicon powder as raw materials. Which is one of the unshaped refractory materials. It is made of refractory aggregate, refractory powder, binders and other additives. It is one of the new type refractory material of don’t need calcination.
Features:
- Good resistance to erosion.
- Abrasiveness resistance.
- High strength.
Application:
Silicon carbide castable mainly used for different parts of cement kiln, the roof of electric arc furnace and steel ladel.
