Corundum mullite fire bricks for sale
Corundum mullite fire brick is mainly made of white fused alumina powder, in which the presence of low melting point oxide impurities will reduce its high temperature performance. White fused alumina sand purity and process formula to meet the requirements of different corundum products using temperature.
Advantages of corundum mullite fire bricks
- Resistance to high temperature creep
- Good high temperature strength
- Thermal shock resistance and erosion resistance
Application of corundum mullite fire bricks
Corundum mullite fire brick is mainly used in petrochemical industry, large and medium-sized ammonia gasifier and magnetic material gas furnace materials, high temperature hot blast furnace, also used in glass furnace and as ceramic firing kiln tools.
