75 # ferrosilicon is commonly used in the high-temperature smelting process of magnesium metal in the Pijiang method magnesium smelting process. It replaces the magnesium in CaO.MgO and consumes about 1.2 tons of ferrosilicon for every ton of magnesium produced It plays a big role in the production of magnesium metal.
The ground or atomized ferrosilicon powder can be used as the suspended phase in the beneficiation industry. It can be used as electrode coating in electrode manufacturing. High silicon ferrosilicon can be used to manufacture silicone and other products in the chemical industry.
Among these uses, the steelmaking industry, foundry industry and ferroalloy industry are the largest users of ferrosilicon. They consume about 90% of ferrosilicon in total. Among various grades of ferrosilicon, At present, the most widely used is 75% ferrosilicon. In the steel-making industry, about 3-5 kg of 75% ferrosilicon is consumed for every 1 t of steel produced.
