What is ferrosilicon used for

Ferrosilicon is used as a deoxidizer in steelmaking. Since silicon and oxygen can easily combine to form silica, ferrosilicon is often used as a deoxidizer in steelmaking. Ferrosilicon can also be used as an alloying element additive and is widely used in low-alloy structural steel, spring steel, bearing steel, heat-resistant steel and electrical silicon steel.
Ferrosilicon is an iron-silicon alloy made from coke, steel scraps and quartz as raw materials and smelted in an electric furnace.

Ferrosilicon is an essential deoxidizer in the steelmaking industry. In Torch Steel, ferrosilicon is used for precipitation deoxidation and diffusion deoxidation.

Ferrosilicon contains a small amount of phosphorus metal compounds, such as calcium phosphide. If it gets damp during transportation or warehouse storage, phosphine will be released, poisoning people in the warehouse or around it.
