Three functions of ferro silicon powder

First, ferro silicon powder is often used as a deoxidizer and alloying agent
In the steelmaking industry, in order to obtain the chemical composition of qualified steel and ensure the quality of steel, in the later stage of steelmaking must be deoxidized, the chemical affinity between silicon and oxygen in ferro silicon powder is very large, so ferro silicon powder is a strong deoxidizer for precipitation and diffusion in steelmaking. Second, ferro silicon powder can be used as a reducing agent in the production process of ferroalloy
In the process of ferro alloy production, not only the chemical affinity between silicon and oxygen is very large, but also the carbon content of high-silicon ferro silicon powder is very low. Therefore, high-silicon ferro silicon powder is a kind of reducing agent commonly used in the production of low-carbon ferroalloys in the ferro alloy industry. Third, iron silicon powder in cast iron industry is often used as inoculant and spheroidizing agent
Cast iron is an important metal material in modern industry, it is cheaper than steel, easy to melt and smelt, has excellent casting performance and much better earthquake resistance than steel. In particular, ductile iron, its mechanical properties reach or approach the mechanical properties 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 nodulation of graphite, so in the production of ductile iron, ferrosilicon is an important inoculant and nodulation agent.
