What is FeSi Alloy？
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. At the same time, ferrosilicon can also be used as alloying element additive, widely used in low-alloy structural steel, spring steel, bearing steel, heat-resistant steel and electrical silicon steel, ferrosilicon in ferroalloy production and chemical industry, commonly used as a reducing agent.
Smelting
Ferrosilicon is made of coke, steel chips, quartz (or silica) as raw materials by electric furnace smelting. In the traditional refining of ferrosilicon, the silicon is reduced from the silica containing SIO2. Smelting ferrosilicon mostly uses metallurgical coke as reducing agent, and steel scrap is the regulator of ferrosilicon.
