Ferrosilicon (FeSi) is an alloy of iron and silicon, used mainly in steelmaking as a deoxidising and alloying component.
How is ferrosilicon made?
The best quality ferrosilicon 75 is produced in an electric arc furnace by reducing silica with coke in the presence of iron (usually obtained from iron scrap or iron ore). Ferrosilicon is usually in the form of shiny metallic grey lumps, but is also available as pre-formed briquettes. Ferrosilicon (commonly abbreviated as FeSi) is an alloy of iron and silicon that also contains other elements in smaller proportions.
Role of ferrosilicon 75 in steel production.
1. product performance: ferrosilicon is a convenient way of adding silicon as an alloying element to improve various properties of the final steel.
2. deoxidisation: ferrosilicon can rapidly remove oxygen from molten steel, thus avoiding the presence of oxides forming inclusions and preventing the loss of ideal elements.
3. slag reduction: when producing stainless steel, the presence of silicon reduces chromium oxides in the molten metal and improves the recovery of chromium metal.
Types of ferrosilicon.
Depending on the requirements of the application, ferrosilicones are usually classified according to the content of several trace components. These categories include：
Low aluminium ferrosilicon - used to prevent the formation of hard Al2O3 and Al2O3-CaO inclusions in various steel grades.
Low and ultra-low carbon ferrosilicon: used to prevent the reintroduction of carbon in the manufacture of stainless and electromagnetic steels.
