Deoxidizer low aluminum Fe si alloy Ferrosilicon granules
Ferro silicon Description
Ferro Silicon is one of the iron silicon alloys made by electric furnace smelting,and it's raw materials is coke,scrap stell,quartz(or silica).Ferro Silicon used as deoxidizer and alloying agents in the steel industry.In order to obtain qualified chemical composition and guarantee the quality of steel,in the last stage of the steel must be deoxidized.The chemical affinity between silicon and oxygen is very large,thus ferrosilicon is strong deoxidizer used in sedimentation and diffusion deoxidation of steel-making.Add a certain amount of silicon in the steel,can significantly improve the strength,hardness and elasticity of steel.

The Use of Ferrosilicon
It is used as an inoculant and spheroidizing agent in the cast iron industry. Cast iron is an important metal material in modern industry. It is cheaper than steel and easy to melt and smelt. It has excellent casting performance and much better seismic resistance than steel. Especially for ductile iron, its mechanical properties are at or close to those of steel. Adding a certain amount of ferrosilicon to cast iron can prevent the formation of carbides in iron and promote the precipitation and spheroidization of graphite. Therefore, in the production of ductile iron, ferrosilicon is an important inoculant (helps precipitate graphite) and nodularizer .
