Ferrosilicon is an important metallurgical material, the main uses include:
· Used as deoxidiser and reducing agent
In the manufacture of steel, need to add ferrosilicon as a deoxidiser to remove the oxide impurities in the steel, and play a reducing effect. Ferrosilicon can effectively improve the quality and toughness of steel.
· Manufacture of cast iron and cast steel
In the production of ductile iron and malleable cast iron, need to add a certain amount of ferrosilicon to adjust the silicon content, in order to obtain the required mechanical properties and toughness.
· Production of silicon alloys
Ferrosilicon and other metals can be made a variety of silicon alloys, such as silicon aluminium alloy, silicon barium alloy, widely used in the manufacture of heat-resistant and corrosion-resistant materials.
· Special glass manufacturing
Some special glass such as quartz glass, optical glass and other manufacturing needs to use ferrosilicon as a flux.
In general, ferrosilicon plays an important role in metallurgy, machinery, building materials, electronics and many other fields. Among them, iron and steel production and silicon alloy manufacturing occupies the main use.
