How is Ferrosilicon used in steelmaking?

It acts as a strong deoxidizer to remove oxygen from molten steel and as an alloying agent to improve the steel's strength, hardness, and magnetic permeability.

What are the main raw materials for producing Ferrosilicon?

The main raw materials include quartzite (silica), metallurgical coke, and steel chips, smelted in an electric furnace.
