Ferrosilicon is an iron alloy composed of iron and silicon. Ferrosilicon is an iron silicon alloy made from coke, steel shavings, quartz (or silica) as raw materials, and silicon manganese alloy is smelted in an electric furnace. Since silicon and oxygen are easy to synthesize silicon dioxide, ferrosilicon is often used as a Oxygen scavenger in steelmaking. At the same time, since a lot of heat is released when SiO2 is generated, it is also beneficial to increase the temperature of molten steel while deoxidizing. Meanwhile, ferrosilicon can also serve 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 commonly used as a reducing agent in ferroalloy production and chemical industry.
