Ferrosilicon,also called industrial silicon or silicon,is a ferroalloy of silicon and iron. It is formed with coke ,steel scrap,silica,in the process of steelmaking, silicon reacts with oxidation to produce SiO2, so ferro silicon can be used as a deoxidizer. Meanwhile when SiO2 is formed, a large amount of heat is released, it is beneficial to increase the temperature of the molten steel.
