What material is ferrosilicon

Ferrosilicon is an alloy of iron and silicon.

Ferrosilicon is an iron-silicon alloy made of coke, steel chips, quartz (or silica) as raw materials and smelted by electric furnace. Since silicon and oxygen are easy to combine into silicon dioxide, iron silicon is often used as a deoxidizer in steelmaking, and due to the release of a large amount of heat when SiO2 is generated, it is also beneficial to improve the temperature of molten steel at the same time.

Ferrosilicon is an essential deoxidizer in steelmaking industry. In torch steel, ferrosilicon is used for precipitation deoxidation and diffusion deoxidation. Brick iron is also used as an alloying agent in steelmaking. Adding a certain amount of silicon to steel can significantly improve the strength, hardness and elasticity of steel, improve the permeability of steel, and reduce the hysteresis loss of transformer steel.

High silicon ferrosilicon or siliceous alloys are used in the ferroalloy industry as reducing agents for the production of low carbon ferroalloys. Adding ferrosilicon to cast iron can be used as inoculant of nodular cast iron, and can prevent the formation of carbide, promote the precipitation and nodulation of graphite, and improve the performance of cast iron.

In addition, ferrosilicon powder can be used as a suspended phase in the mineral processing industry, and as a coating for welding rods in the welding rod manufacturing industry. High silicon iron silicon can be used to prepare semiconductor pure silicon in the electrical industry, and can be used to manufacture silicone in the chemical industry.
