DESCRIPTION
Ferrosilicon is a ferroalloy composed of iron and silicon. Ferrosilicon is an iron silicon alloy made from coke, steel chips,quartz by electric furnace smelting.Because silicon and oxygen are easily converted into silicon dioxide, ferrosilicon is often used as deoxidizer in steelmaking. At the same time, due to a large amount of heat released during the formation of SiO2, it is beneficial to increase the temperature of molten steel while deoxidizing.ferrosilicon can also be used as alloying element additive, which is widely used in low-alloy structural steel, spring steel, bearing steel, heat-resistant steel and electrical silicon steel.
