Ferrosilicon

Ferrosilicon is made from coke, steel scrap, quartz (or silica) and smelted in an electric furnace. Silicon and oxygen are readily synthesized into silica. Therefore, ferrosilicon is often used in steelmaking as a deoxidizer, and at the same time, a large amount of heat is released during the generation of SIO2, and it is also advantageous to increase the temperature of the molten steel while deoxidizing. Ferrosilicon is added as an alloying element.

Widely used in low alloy structural steel, combined steel, spring steel, bearing steel, heat resistant steel and electrical silicon steel, outside the ferrosilicon in the ferroalloy production and chemical industry, often used as a reducing agent. The silicon content is 95%-99%. Pure silicon is commonly used to make single crystal silicon or to formulate non-ferrous metal alloys.
