What is Ferro Silicon?
Ferro silicon (FeSi) is an alloy of iron and silicon that is principally used in steelmaking for deoxidation and as an alloying component. Ferro silicon is produced by reduction of silica or sand with coke in the presence of iron. The ferro silicon usually takes the form of shiny, metallic-grey lumps, but is also available as pre-formed briquettes.
What are the Types of Ferro Silicon?
Low-carbon Ferro Silicon and Ultra-low-carbon Ferro Silicon
Used to avoid re-introducing carbon during the manufacture of stainless steel and electrical steel.
Low-titanium (high-purity) Ferro Silicon
Used to avoid TiN and TiC inclusions in electrical steel and some special steels.
Low-aluminium Ferro Silicon
Used to avoid the formation of hard Al2O3 and Al2O3–CaO inclusions in a range of steel types.
Special Ferro Silicon
A general term that covers a range of tailor-made products containing other alloying elements.
What is Ferro Silicon Used for?
Ferro silicon is an essential deoxidizer in steelmaking industry. In steelmaking, ferro silicon is used for precipitation deoxidation and diffusion deoxidation. Brick iron is also used as an alloying agent in steelmaking.
Used as inoculant and spheroidizer in cast iron industry. In the production of ductile iron, ferro silicon is an important inoculant (to help precipitate graphite) and spheroidizer.
Used as reducing agent in ferroalloy production. Not only is the chemical affinity between silicon and oxygen great, but the carbon content of high silicon ferro silicon is very low. Therefore, high silicon ferro silicon (or siliceous alloy) is a commonly used reducing agent in the production of low carbon ferroalloy in the ferroalloy industry.
75 ferro silicon is often used in the high temperature smelting process of magnesium, the magnesium replacement in CaO, MgO, each one ton of magnesium will consume about 1.2 tons of ferro silicon, which plays a great role in the production of magnesium.
Ferrosilicon products are widely used in Diamond Processing plants, in the dense media separation process. Ferrosilicon powders in combined with a liquid base to form a pulp of the desired density. Diamond bearing material is the submerged into the pulp, which will ultimately separate the diamonds from other materials via gravity.
Heavy media separation: Ferrosilicon is widely used in the metallurgical industry for the processes of atomisation, melting and heavy media separation reactions.
