1.excellent deoxidizer .
2.improve the intensity of the steel .
3.widely used in steel industry .
4.pure,efficient.

Ferro silicon 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.

 

Ferro silicon 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.

 

Reduce the tendency of white iron and the relative hardness.
High anti-decline ability. Prevent declining of inoculant

It intenses the graphite core and thinning the graphite core, promotes the obtaining of A-type graphite in gray iron and improving the roundness of graphite in nodular iron.
Reduce the tendency of white iron and reduce the relative hardness.
High anti-decline ability. Prevent declining of inoculant and nodular iron.
Enhance the section uniformity and prevent the shrink tendency.
Steady chemical composition. Even processing granularity. Small deviation in quality and ingredients.
Low melting point(approaching 1300°C). Easy for melting absorb and has little dross.
Special inoculant can be produced according to customer’s demand. 
Granularity supplying: 0.2-0.7mm,0.7-1.0mm,1.0-3.0mm,3.0-8.0mm.
