ferrosilicon is a kind of deoxidizer, essential to steel-making. It is widely used in the steel-making and foundry. Ferrosilicon is used in precipitation desoxydation and diffusible desoxydation in the process of steel-making. A certain amount of silicon was added into the steel can help improve its intensity. Hardness and flexibility significantly. It also has a big effect on improving the permeability of steel, bringing down the hysteresis loss of transformer steel. Ferrosilicon is the essential deoxidizer in the steel industry, widely used in steel industry and foundry industry. In steel-making, ferrosilicon is used in precipitation desoxydation and diffusible desoxydation. When a volume of silicon is added in, the steel strength, hardness, and elasticity will be enhanced obviously.
furthermore, it also increases the magnetic conductivity of the steel, while having obvious effect in reducing magnetic hysteresis loss.
application:
1. Ferrosilicon is often used as deoxidizer in steel- making.
2. Ferrosilicon also can be used as alloy elements join agent, which is widely used in low alloy steel, non-ferrous metal, bearing steel, heat-resistant steels and electrician silicon-steel.
advantages:
1. Iimprove the hardness, strength, elasticity and permeability of steel
2. Lower the hysteresis loss of the transformer.
3. To prevent the formation of carbides.
4. Promote the precipitation and nodulization of graphite.
5. Perfect the performance and nature of casting iron
