Overview of ferrosilicon
Silicon iron is an iron alloy, and its composition is about 65% to 70% silicon and 30% to 35% iron. It is an important alloy material with high chemical activity and thermal stability.
Ferrosilicon is an important raw material for steel, metallurgy, casting and other industries, and is widely used because of its characteristics of reducing carbon content, oxidation resistance and corrosion resistance, and high-quality reinforcement materials.
the main uses of ferrosilicon
(1) Iron and steel industry
As an important ferroalloy, ferrosilicon is mainly used in iron and steel smelting industry. It can be used as reducing agent and alloying element, and added to the steel furnace to promote decarburization and deoxidation of steel and make the quality of steel more excellent.
At the same time, ferrosilicon can also prolong the flow time of slag, reduce the viscosity of slag and improve production efficiency.
(2) Foundry industry
Ferrosilicon is also widely used in foundry industry. It can increase the silicon content in iron, copper and nickel-based alloys, and improve the tensile strength, heat resistance and corrosion of the alloys.
In addition, ferrosilicon can also be used as a desulfurizer to absorb and reduce gases (such as oxygen, nitrogen, hydrogen, etc.) in the casting and promote the solidification of the casting.
(3) Chemical industry
As an important chemical raw material, ferrosilicon is also widely used in silicone, silicone oil, silicone rubber, diatomite and other industries. Ferrosilicon can be used as a polymer reinforcing agent to improve the wear resistance and aging resistance of products.
Meanwhile, ferrosilicon can also increase the oxidation stability and increment of oil products and improve the quality of oil products.
At the same time, ferrosilicon also plays an important role in many industries, such as chemical industry, food industry and pharmaceutical industry, which promotes the development of these industries.
