AI Technical Summary
Technical Problem
In traditional manganese-silicon alloy smelting methods, it is difficult to effectively control the phosphorus impurity content, which affects the alloy quality and steel performance.
Method used
By pre-treating the raw materials, including crushing, screening and adding binders to form spherical particles, and then smelting them in an electric furnace, the contact area between slag and metal is increased by using a shaking reaction and dephosphorizing agent injection, which promotes slag-iron separation and chemical reaction to transfer phosphorus impurities to the slag phase.
Benefits of technology
It significantly reduces the phosphorus content in low-phosphorus silicon-manganese alloy products, improving alloy purity and quality.
