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.
