The Use Of Ferro Silicon

            (1) Used as deoxidation agent and alloy agent in steelmaking industry. In order to obtain the chemical composition of qualified steel and ensure the quality of steel, in the final stage of steelmaking must be deoxidation, the chemical affinity between silicon and oxygen is very large, so ferrosilicon is a stronger deoxidation agent for precipitation and diffusion deoxidation. Adding a certain amount of silicon to the steel can significantly improve the strength of the steel, the hardness and elasticity are thus used in the smelting of structural steels (0.40-1.75%), tool steels (including Sio. 30-1.8%), spring steels (including Sio 40-2.8%), and silicon steel (including silicon 2.81-4.8%) for Transformers. In addition, in the steelmaking industry, the use of ferrosilicon powder at high temperature can emit a lot of heat, which is often used as a heating agent for ingot cap to improve the quality and recovery of ingot.Ferro Silicon

           (2) used as inoculant and spherical agent in the cast iron industry. Cast iron is an important metal material in modern industry, it is cheaper than steel, easy to melt smelting, has excellent casting performance and much better than steel, especially ductile iron, its mechanical properties reach or close to the mechanical properties of steel. The addition of a certain amount of ferrosilicon in cast iron can prevent the formation of carbide in iron, promote the precipitation and spheroidal graphite, so in nodular cast iron, Ferrosilicon is an important inoculant (helping to precipitate graphite) and a pellet.

           (3) Ferroalloy production used as reducing agent. Not only is there a strong chemical affinity between silicon and oxygen, but the carbon content of high silicon ferrosilicon is very low. Therefore, high silicon ferrosilicon (or silicon alloy) is a kind of reducing agent used in ferroalloy industry when producing Low-carbon Ferroalloy.Ferro Silicon

           (4) Other uses. The Ferrosilicon powder, which has been milled or atomized, can be used as suspension phase in the mineral processing industry. In the welding rod manufacturing can be used as a coating electrode. High silicon ferrosilicon can be used in the chemical industry to make products such as silicone.Ferro Silicon
