Used as a reducing agent in the production of ferroalloys. Not only the chemical affinity between silicon and oxygen is great, but also the carbon content of high silicon ferrosilicon is very low. Therefore, high-silicon ferrosilicon (or silicon alloy) is a reducing agent commonly used in the production of low-carbon ferroalloys in the ferroalloy industry.
75# ferrosilicon is often used in the high-temperature smelting process of metal magnesium in the Pidgeon method of magnesium smelting to replace the magnesium in CaO.MgO. For every ton of metal magnesium produced, about 1.2 tons of ferrosilicon will be consumed, which plays a great role in the production of metal magnesium.
For other uses. Finely ground or atomized ferrosilicon powder can be used as a suspension phase in the mineral processing industry. In the welding rod manufacturing industry, it can be used as a coating for welding rods. High-silicon ferrosilicon can be used in the chemical industry to make products such as silicone.
Among these uses, steelmaking industry, foundry industry and ferroalloy industry are big users of ferrosilicon. They consume more than 90% of ferrosilicon in total. Among the various grades of ferrosilicon, 75% ferrosilicon is currently the most widely used. In the steelmaking industry, about 3-5kg of 75% ferrosilicon is consumed per 1 ton of steel produced.
