About Ferrosilicon

Ferrosilicon is a ferroalloy, an alloy of iron and silicon with between 15% and 90% silicon. It contains a high proportion of iron silicides and has a melting point is about 1200 °C to 1250 °C with a boiling point of 2355 °C. It also contains about 1 to 2% of calcium and aluminium.


Like most ferroalloys, ferrosilicon is used in steel manufacturing and in foundries as a source of silicon in the production of carbon steel, stainless steel, and other ferrous alloys for its de-oxidising properties, to prevent loss of carbon from the molten steel. It can be used to make other ferroalloys and is also used in the manufacture of silicon, corrosion-resistant and high-temperature resistant ferrous silicon alloys, and silicon steel for electro-motors and transformer cores.


Ferrosilicon is a basis for the manufacture of prealloys like magnesium ferrosilicon (Ferrosilcon Manganese or FeSiMg), used for modification of melted malleable iron; FeSiMg contains between 3% and 42% of magnesium and small amounts of rare earth metals.


Ferrosilicon is also important as an additive to cast irons for controlling the initial content of silicon. It is produced by the reduction of silica or sand with coke in the presence of scrap iron, millscale, or some other source of iron. Ferrosilicon with a silicon content of up to about 15% are made in blast furnaces lined with acid fire bricks. Those with a higher silicon content are made in electric arc furnaces. An over-abundance of silica is used to prevent the formation of silicon carbide.

Siliconmanganese

Silicomanganese (SiMn) is a ferroalloy with high contents of manganese and silicon. It is made by heating a mixture of the oxides manganese oxide (MnO2), silicon dioxide (SiO2), and iron oxide (Fe2O3), with carbon in a furnace. They undergo a thermal decomposition reaction. It is used as a deoxidizer and an alloying element in steel. The standard grade silicomanganese contains 14 to 16% of silicon, 65 to 68% of manganese and 2% of carbon. The low carbon grade SiMn has carbon levels from 0.05 to 0.10%.
