Ferrosilicon powder An iron alloy composed of silicon and iron, which is then ground into a powdery substance and used as a deoxidizer in steelmaking and iron making.
Function 1: Ferrosilicon powder is often used as a deoxidizer and alloying agent
In the steel making industry, in order to obtain qualified steel with chemical composition and ensure the quality of steel, deoxidation must be carried out in the later stages of steel making. The chemical affinity between silicon and oxygen in ferrosilicon powder is high, so ferrosilicon powder is a strong deoxidizer for steel making, used for precipitation and diffusion deoxidization.
Function 2: Ferrosilicon powder can be used as a reducing agent in the production process of ferroalloys
In the process of ferroalloy production, ferrosilicon powder not only has a strong chemical affinity between silicon and oxygen, but also has a low carbon content in high silicon ferrosilicon powder. Therefore, high silicon ferrosilicon powder is a commonly used reducing agent in the production of low-carbon ferroalloys in the ferroalloy industry.
Function 3. Ferrosilicon powder in the cast iron industry is often used as an inoculant and nodularizing agent
Cast iron is an important metal material in modern industry. It is cheaper than steel, easy to melt and smelt, and has excellent casting properties and much better seismic resistance than steel. In particular, ductile iron has mechanical properties that reach or approach those of steel. Adding a certain amount of ferrosilicon powder to cast iron can prevent the formation of carbides in iron and promote the precipitation and spheroidization of graphite. Therefore, ferrosilicon is an important inoculant and nodularizing agent in the production of ductile iron.
