Ferroalloys
Ferrosilicon
This alloy is a mixture of iron and silicon, which is produced through heating, reduction and melting of iron ore and silica (quartz) by carbon, mainly in electric arc furnaces or induction furnaces.
FwSiMn
Ferrosilicon manganese is the second most widely used ferroalloy in industries. This alloy is obtained by webbing sources of silicon, manganese and iron in the presence of reducing agents such as coke or coal in an electric arc furnace. Because the production of ferrosilicon-
manganese requires a higher temperature, its production is much more difficult than silicon-manganese.
Ferromanganese
Ferromanganese metal alloy is composed of a combination of iron and manganese and usually some impurities of elements such as carbon, phosphorus and sulfur. The amount of manganese present in this composition is at least 65% and at most 95%, and it is especially used in the steel and casting industry.
