Ferro-silicon powder is an alloy of iron and silicon, which is then ground into a powder, used as a deoxidizer in steelmaking and iron-making.The characteristics of ferrosilicon powder, used as inoculant and spheroidizing agent in the cast iron industry, is an important inoculant (helps to precipitate out graphite) and spheroidizing agent in the production of nodular cast iron, and is used as reducing agent in the production of ferroalloy.75# ferrosilicon is often used in the high temperature smelting process of metal magnesium in The Pijiang process. The magnesium in CaO.MgO is replaced. Every ton of metal magnesium consumes about 1.2 tons of ferrosilicon, which plays a great role in the production of metal magnesium.Among these USES, the steelmaking industry, the casting industry and the ferroalloy industry are the largest users of ferrosilicon.Together, they consume more than 90 percent of ferrosilicon.Of the various grades of ferrosilicon, the most widely used is 75% ferrosilicon.In the steelmaking industry, about 3-5kg75% of ferrosilicon is consumed for every 1t of steel produced.
