AI Technical Summary
In iron and steel metallurgy, existing protective slags are prone to solidification at high temperatures, which leads to unstable quality of molten steel during casting and makes it difficult to effectively reduce gas and oxide inclusions in the steel, thus affecting the quality of the cast billet.
A low-melting-point composite molten salt protective slag is adopted, which is composed of inorganic non-metals, silicates, alkali metal oxides and fluorides. It is prepared through a specific ratio and process to form a protective slag with good fluidity and lubricity, which lowers the melting point and adsorbs gases and oxides, thereby improving the purity of molten steel.
This achieves good fluidity and lubricity of the protective slag at high temperatures, reduces billet pulling resistance, lowers energy consumption, improves the purity of molten steel and the quality of the cast billet, and enhances the stability and efficiency of the casting process.
