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
