[0002] Si-Mn alloy is primarily composed of manganese, silicon, iron, and small amounts of carbon and other elements, typically containing approximately 65% ​​manganese and 30% silicon, with lower concentrations of other elements. It is a widely used and high-volume ferroalloy. Si-Mn alloy is produced in submerged arc furnaces (electric furnaces) using the slag method. Si-Mn alloy powder is typically used as a base during the casting process.

[0003] In the existing technology, since the same industry only uses powder as a base material for casting manganese silicon alloy in a molten state, the remaining powder still accounts for about 14% of the total product. Due to poor powder utilization, serious powder waste occurs. Therefore, how to increase the use of manganese silicon alloy powder in the smelting and casting process has become an urgent problem to be solved in the research and development of production processes. It is also difficult to quickly replace the next casting plate for casting. Therefore, how to improve the efficiency of manganese silicon alloy casting is also something that needs to be improved.
