Used as deoxidizer and alloying agent in steelmaking industry.
Used as inoculant and nodulator in the cast iron industry.
Used as a reducing agent in the production of ferroalloy.
75# ferrosilicon is often used in the high temperature smelting process of magnesium metal in the Pijiang process, replacing the magnesium in CaO.MgO, and consuming about 1.2 tons of ferrosilicon for every ton of magnesium metal produced, which plays a great role in the production of magnesium metal.
For other purposes. The fine or atomized ferrosilicon powder can be used as a suspended phase in the mineral processing industry. In the welding rod manufacturing industry can be used as welding rod coating. High silicon iron silicon is used in the chemical industry to make products such as silicone.
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% of the ferrosilicon. In a variety of different grades of ferrosilicon, the most widely used is 75% ferrosilicon. In the steelmaking industry, about 3-5kG 75% of ferrosilicon is consumed per 1t of steel produced.
