Medium frequency melting furnace smelting deoxy how it
What you are asking is deoxidation of steelmaking:
Directly added deoxidizer: generally iron alloy, such as ferromanganese, ferrosilicon, aluminum iron, silicon manganese alloy. Directly added to molten steel
Diffusion deoxidation method: adding deoxidizer such as carbon powder, ferrosilicon powder, aluminum powder, etc. to the slag
Vacuum deoxidation: the molten steel is placed under vacuum to reduce the partial pressure of CO gas to achieve the purpose of deoxidation.
