Ferrosilicon is an iron alloy composed of iron and silicon. Ferrosilicon is an iron-silicon alloy made of coke, steel shavings, quartz (or silica) as raw materials and smelted in an electric furnace. Because silicon and oxygen are easily converted into silica, ferrosilicon is often used as a deoxidizer during steelmaking. At the same time, because silica emits a lot of heat, it is also beneficial to increase the temperature of molten steel while deoxidizing. At the same time, ferrosilicon can also be used as an alloying agent. It is widely used in low-alloy structural steel, spring steel, bearing steel, heat-resistant steel and electrical silicon steel. Ferrosilicon is often used as a reducing agent in the production of ferroalloys and the chemical industry.

        Ferrosilicon is an essential deoxidizer in the steelmaking industry. High silicon ferrosilicon or silicon alloys are used as reducing agents in the production of low carbon iron alloys in the ferroalloy industry. Ferrosilicon is widely used in steel industry, foundry industry and other industrial production.
