Since silicon and oxygen are easily combined to produce silicon dioxide, ferrosilicon is used as a deoxidizer in steelmaking production. When the silicon in the ferro silicon combines with oxygen, a large amount of heat is released due to the formation of SiO2, which is also beneficial to increase the temperature of the molten steel while deoxidizing. In the steelmaking industry, about 3-5kg of ferro silicon 75 is consumed for 1 ton steel produced.
Ferro silicon 75 is commonly used in the production of magnesium metal, and it takes about 1.2 tons of ferrosilicon 75 to produce 1 ton of magnesium. Ferrosilicon can also be used as alloying element additives, widely used in low-alloy structural steel, spring steel, bearing steel, heat-resistant steel and electrical silicon steel.
