Ferro Silicon Description

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.

Ferrosilicon particles also can be used as an inoculant in casting.
