Ferrosilicon is an alloy with silicon (70%~75%) and iron (20%~25%) as the main components. It is smelted by reducing quartz (SiO₂) and coke (C) in an electric furnace at high temperature. It is the “basic material” of the metallurgical industry. It has the functions of deoxidation, silicon addition and alloying. It is widely used as a steelmaking deoxidizer, casting inoculant and ferroalloy production. It can significantly improve the fluidity of molten steel, the strength of castings and the magnetic conductivity of silicon steel. At the same time, it is used as a reducing agent for magnesium smelting, supporting the efficient operation of the steel, casting and new energy industry chains. It is a core metallurgical additive that balances performance optimization and cost control.
