Application

Ferro silicon is widely used in the steel-making, iron-casting, low-carbon ferroalloy producing:

1.  In the steel-making field: Ferro silicon is used as deoxidizer and alloying agent. Adding a certain amount of Fe- Si to the steel can obviously improve the strength, hardness, elasticity and permeability of steel.

2.  In the iron casting: It is used as ball mile agent and alloying agent. Adding ferrosilicon to cast iron, it can prevent the formation of carbide and promote the precipitation and spheroidization of graphite.

3. High-silicon ferrosilicon (or silicon alloy) is a common reducing agent used to produce low-carbon ferroalloys in the ferroalloy industry.   

4. High silicon ferrosilicon can be used in the electrical industry to produce semiconductor pure silicon, which can be used in the chemical industry to manufacture silicones and so on.
