The ferrosilicon powder is siliver grey,powder,and it is mainly used in smelting,steelmaking,casting.

 The ferrosilicon powder takes the coke, scrap steel, and silica as raw materials ,which is made by the electrosmelting.

Application

It is often used as deoxidizer in steelmaking. It may be widely used in the produce of low alloy   structural steel, alloysteel,spring steel, bearing steel, heat-resistant steel and electrical silicon. It also can be used as reductant in ferroalloy making and chemistry engineering. It can also be used as inoculant of the nodular cast iron when it is added.

It may be widely used in  improving the strength of steel, the hardness and elasticity. By adding a certain amount of ferrosilicon in cast iron can prevent the formation of iron carbide, and promote the precipitation of graphite and globalization.
