Method for optimizing slag corrosion resistance and permeation resistance of low-carbon magnesium-carbon material

The invention discloses a method for optimizing slag corrosion resistance and permeation resistance of a low-carbon magnesium-carbon material, and belongs to the field of magnesium-carbon materials for metallurgy. The method comprises the specific steps of raw material pretreatment, compression molding and hardening treatment. The method is characterized in that polycrystalline silicon waste and silicon carbide ceramic waste are introduced in the material mixing stage, and a reinforcing phase is formed in situ through valuable elements in the waste so as to enhance the slag resistance of the low-carbon magnesium-carbon material. Meanwhile, the main components silicon and silicon carbide of the waste can react with slag at high temperature, and a high-melting-point protective layer is formed on the surface of the magnesium-carbon material. According to the invention, the defect of poor slag resistance of the existing low-carbon magnesium-carbon material is solved by simple raw materialadjustment, and the metho
