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.
1).In the iron and steel smelting, ferrosilicon often used as deoxidize agent.
2). Improve the hardness, strength, elasticity and permeability of steel.
3). Lower the hysteresis loss of the transformer.
4). To prevent the formation of carbides.
5). Perfect the performance and nature of casting iron .
