Ferrosilicon (FeSi) is an alloy of iron and silicon that is principally used in steelmaking for deoxidation and as an alloying component. Elkem is one of the largest suppliers of premium-grade ferrosilicon ferroalloys worldwide, and we’re ready to help you identify the best product for your application.
Application
In steelmaking, ferrosilicon is used for:
· Product performance – Ferrosilicon is a convenient way of adding silicon as an alloying element, to improve various properties of the final steel.
· Slag reduction – In the manufacture of stainless steels, the presence of silicon reduces chromium oxides in the melt, improving recovery of metallic chromium.
· Deoxidation – Ferrosilicon provides quick-acting removal of oxygen from the melt, so avoiding the presence of inclusion-forming oxides and avoiding loss of desirable elements.
· Fuel – Some steel mills add ferrosilicon to the melt so that it can be burnt off to get heat into the furnace, and so reduce energy costs.
It is used as a reducing agent in the silicothermic reduction process to refine precious metals.
