Ferro Silicon
Ferrosilicon is used to reduce metals from their oxides and to deoxidize steel and other ferrous alloys as a silicon source. Ferro Silicon is a silicon and iron alloy. Silicon serves as a potent oxidant in steel. Used mainly in particular steels and in mild steel in limited quantities. Ferro silicon is also used to make silicon, ferrous silicon alloys that are corrosion-proof and high-temperature resistant, and silicon steel for electro motors and transformer cores.
Ferrosilicon (FeSi) is an alloy of silicon and iron with a very high silicon content of between 10% and 90%. It is used as a master alloy in steel manufacturing, which is added in small quantities in order to change the properties of the melt, the freezing process and the final product.
Ferrosilicon is considered to have good abrasion resistance, excellent corrosion resistance, relatively high gravity, and high magnetism, allowing fast magnetic recovery. The melting point and density of ferrosilicon depends on its quality of silicone and is relatively inexpensive in cost.
Uses of Ferro Silicon
It acts as a manufacturer of silicon alloys.
It acts as a source of silicon that reduces metals from oxides
It is used in manufacture of silicon, and ferrous silicon alloys
It helps in manufacture of cast iron
It also manufactures pre-alloys like magnesium ferrosilicon
Malleable iron is modified with it
It is used in a process called pidgeon to make magnesium
For the manufacture of pure silicone semiconductor in the electrical industry and copper silicone in the chemical industry

Ferro Silicon Ferro Silicon has a melting point of 1200°C to 1250°C with a boiling point of 2355°C and Ferro Silicon contains about 2% of calcium and alluminium. Ferro Silicon, as an additive to the production process of ferrous metals, will impart several desirable properties upon the resultant alloy. Some of the primary benefits of adding Ferro Silicon to an alloy is to improve the corrosion resistant properties of the new compound, as well as to add to the high temperature heat- resistance properties of the new alloy, for example, in the production of silicon steel for use in transformer cores. Ferro Silicon is an atomised alloy, which is formed by combining iron and silicon with a silicon content range of 15% to 90%. Ferro Silicon is a universal “heat-blocker” used in the production of carbon and stainless steels.
FerroSilicon uses coke, quartz (or silica) as raw material,and is made by electric furnace.Ferrosilicon is widely used in the steel making,iron casting ,low-carbon ferroalloy producing. Application: 1.In the steel making field,Ferrosilicon is used as deoxidizer and alloying agent to precipit and diffuse deoxidation.Adding a certain amount silicon of fe-si to the steel can obviously improve the strength ,hardness ,elasticity and permeability of steel. 2.In the iron casting,ferrosilicon is used as ball mile agent and alloying agent, especially in the nodular iron casting,Adding ferrosilicon to cast iron,it can prevent the formation of carbide and promote the precipitation of graphite and the nodulizing.then the mechanical capacity can be the same of steel's. 3.High-silicon ferrosilicon can be used for the production of the low-carbon reductant in ferro alloy industry. 4.In addition, ferrosilicon powder can be used as a suspended phase in the mineral processing industry and coatings for welding electrodes in the electrode manufactruing.
