is a ferroalloy composed of iron and silicon. Ferrosilicon is an iron silicon alloy made from coke, steel chips,quartz by electric furnace smelting.Because silicon and oxygen are easily converted into silicon dioxide, ferrosilicon is often used as deoxidizer in steelmaking. At the same time, due to a large amount of heat released during the formation of SiO2, it is beneficial to increase the temperature of molten steel while deoxidizing.ferrosilicon can also be used as alloying element additive, which is widely used in low-alloy structural steel, spring steel, bearing steel, heat-resistant steel and electrical silicon steel.

Applications
mainly used to
(1) It is used as deoxidizer and alloying agent in steelmaking industry. In order to obtain steel with qualified chemical composition and ensure the quality of steel, deoxidation must be carried out in the final stage of steelmaking. The chemical affinity between silicon and oxygen is very large, so ferrosilicon is a strong deoxidizer for precipitation and diffusion deoxidation. Adding a certain amount of silicon to the steel can significantly improve the strength, hardness and elasticity of the steel. Therefore, ferrosilicon is also used as alloying agent when smelting structural steel (silicon 0.40-1.75%), tool steel (silicon 0.30-1.8%), spring steel (silicon 0.40-2.8%) and transformer silicon steel (silicon 2.81-4.8%). At the same time, it is an effective new technology to improve steel quality, reduce cost and save iron by improving inclusion morphology and reducing gas element content in liquid steel. It is especially suitable for deoxidation of continuous casting molten steel. Practice has proved that ferrosilicon not only meets deoxidation requirements of steelmaking, but also has desulfurization performance, and has the advantages of large ratio and strong penetration.In addition, in the steel-making industry, ferrosilicon powder is often used as heating agent of ingot cap to improve the quality and recovery rate of ingot, because it can release a lot of heat at high temperature.
(2) It is used as inoculant and nodularizing agent in cast iron industry. Cast iron is an important metal material in modern industry. It is cheaper than steel, easy to melt and smelt, and has excellent casting performance and much better seismic capacity than steel. In particular, the mechanical properties of ductile iron reach or approach the mechanical properties of steel. Adding a certain amount of ferrosilicon to cast iron can prevent the formation of carbide in iron and promote the precipitation and spheroidization of graphite. Therefore, in the production of ductile iron, ferrosilicon is an important inoculant (helping to precipitate graphite) and spheroidizing agent.
(3) It is used as reducing agent in ferroalloy production. Not only the chemical affinity between silicon and oxygen is very high, but also the carbon content of high silicon ferrosilicon is very low. Therefore, high silicon ferrosilicon (or siliceous alloy) is a reducing agent commonly used in the production of low carbon ferroalloy in ferroalloy industry.
(4) 75 ferrosilicon is often used in the high-temperature smelting process of metallic magnesium in the process of magnesium smelting by Pijiang process. Replacing the magnesium in cao.mgo will consume about 1.2 tons of ferrosilicon for each ton of metallic magnesium production, which plays a great role in the production of metallic magnesium.
(5) Other uses. The ground or atomized ferrosilicon powder can be used as suspended phase in mineral processing industry. It can be used as coating for welding rod in welding rod manufacturing industry. High silicon ferrosilicon can be used in chemical industry to produce silicone and other products.
