Ferrosilicon
Used as a deoxidizer and alloying agent in the steelmaking industry. In order to obtain steel with qualified chemical composition and ensure its quality, deoxidation must be carried out in the final stage of steelmaking. The chemical affinity between silicon and oxygen is high, so ferrosilicon is a strong deoxidizer for precipitation and diffusion in steelmaking. Adding a certain amount of silicon to steel can significantly improve its strength, hardness, and elasticity. Therefore, in the smelting of structural steel (containing 0.40-1.75% silicon), tool steel (containing 30-1.8% SiO), spring steel (containing 40-2.8% SiO), and silicon steel for transformers (containing 2.81-4.8% silicon), silicon iron is also used as an alloying agent

Simultaneously improving the morphology of inclusions and reducing the content of gas elements in molten steel is an effective new technology for improving steel quality, reducing costs, and saving iron. Especially suitable for the deoxidation requirements of continuous casting steel, practice has proven that ferrosilicon not only meets the deoxidation requirements of steelmaking, but also has desulfurization performance and advantages such as high specific gravity and strong penetration.
In addition, in the steelmaking industry, silicon iron powder is often used as a heating agent for steel ingot caps to improve the quality and recovery rate of steel ingots by utilizing the characteristic that silicon iron powder can release a large amount of heat during high-temperature olefinic firing
Cast iron is an important metal material in modern industry. It is cheaper than steel, easier to melt and smelt, and has excellent casting performance and much better seismic resistance than steel. Especially ductile iron, its mechanical properties reach or approach those of steel. Adding a certain amount of ferrosilicon to cast iron can prevent the formation of carbides in iron, 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
Used as a reducing agent in ferroalloy production
Not only is there a strong chemical affinity between silicon and oxygen, but high silicon silicon iron also has a low carbon content. Therefore, high silicon ferrosilicon (or siliceous alloys) is a commonly used reducing agent in the production of low-carbon ferroalloys in the ferroalloy indus
