Magnesite based refractory fire brick Aluminun magnesium carbon bricks for Steel industry
Application:
Aluminum magnesium carbon refractory fire brick is the refractory product that made of super high alumina bauxite or corundum sand, magnesia sand and flaky graphite, added with appropriate Si powder, Al powder, SiC powder, takes resin as binder, molding under high stress which can be used after processing at 200~300 ℃ that without burning. Aluminum magnesium carbon bricks are mainly used for ladle lining, molten pool parts and bottoms of large-scale tundish and RF, large converters and ultra-high-power electric furnace etc.
Aluminum magnesium carbon refractory fire brick has the advantages of low porosity, strong resistance to slag erosion, good thermal shock resistance, resistance to flaking, safe use, less slag staining, and easy unpacking.
