High-grade bauxite clinker, fused corundum, fused magnesia and high carbon graphite are used as main raw materials, and phenolic resin is used as binder for high-pressure moulding. Al-Mg-C bricks have the characteristics of low porosity, strong slag corrosion resistance and erosion resistance, especially spinel formed in the process of use, which further strengthens the anti-spalling and slag resistance of products, and enhances the anti-melting corrosion ability of products. It is suitable for ladle wall and bottom.
