Ferro Silicon 70%/FeSi 70%

Ferro silicon70% is widely used in the steel making, iron casting ,low-carbon ferro alloy producing:In the steel making field, Ferro silicon is used as deoxidizer and alloying agent to precipit anddiffuse deoxidation. Adding a certain amount silicon of Fe-Si to the steel can obviously improvethe strength , hardness ,elasticity and permeability of steel.In the iron casting, it is used as ballmile agent and alloying agent especially in the nodular iron casting, Adding ferro silicon to cast iron ,it can prevent the formation of carbide and promote the precipitation of graphite and the nodulizing. Then the mechanical capacity can be the same of steel's.
