Ferro-silicon is an alloy of iron and silicon.Ferro-silicon is a ferro-silicon alloy made from coke, steel shavings, quartz (or silica) and smelted in an electric furnace.Silicon and oxygen are easily combined to form silicon dioxide, so ferrosilicon is often used as deoxidizer in steelmaking. At the same time, SiO2 generates a lot of heat, which is beneficial to increase the temperature of molten steel while deoxidizing.At the same time, ferro-silicon can also be used as an admixture of alloy elements, widely used in low-alloy structural steels, spring steels, bearing steels, heat-resistant steels and electrical silicon steels. Ferro-silicon is commonly used as a reducing agent in ferro-alloy production and ch
