High grade bauxite clinker, fused alumina, fused magnesia and high carbon graphite are used as the main raw materials and phenolic resin is used as the bonding agent. Aluminum-magnesia carbon brick has the characteristics of low porosity, strong slag erosion resistance, erosion resistance, etc., especially in the process of use to form spinel, which further enhances the product's resistance to spalling and slag resistance, and enhances the product's resistance to melting erosion. Suitable for steel bag wall and bottom.
