硅铁

●用途及应用范围：主要应用于钢铁工业和铸造工业.炼钢中沉淀脱氧和扩散脱氧，生产球墨铸铁孕育剂和球化剂。

●优点：提高钢的硬度、强度、弹性和磁导率；降低变压器的磁滞损。阻止碳化物形成，促进石墨的析出和球化，改善铸铁性能。

●化学成分：硅、铁、铝、钙

Ferro silicon

●    Application: Mainly used in steel and iron industory and casting industory.In steel-making,it is used to precipitate and diffuse oxygen.In the production of ductile casting iron,it is an important inoculant and nodulizer.

●    Advantages: Improve the hardness、strength、elasticity and permeabilityof steel;Lower the hysteresis loss of the transformer. To prevent the formation of carbides,Promote the precipitation and nodulization of graphite,Perfect the performance and nature of casting iron.

●  Chemical composition:Si、Fe、Al、Ca
