Description
Ferrosilicon is an iron alloy composed of iron and silicon. Ferrosilicon is an iron-silicon alloy made by smelting in an electric furnace using coke, steel scraps, and quartz (or silica) as raw materials.

Application
(1) Ferrosilicon is a deoxidizer in the steelmaking industry. In steelmaking, ferrosilicon is used for precipitation deoxidation and diffusion deoxidation. Brick iron is also used as an alloying agent in steelmaking.
(2) In the cast iron industry, it is used as an inoculant and spheroidizer. In the production of ductile iron, ferrosilicon is an important inoculant (helping to precipitate graphite) and spheroidizer.
(3) In the production of ferroalloys, it is used as a reducing agent. Not only is the chemical affinity between silicon and oxygen very high, but the carbon content of high-silicon ferrosilicon is also very low. Therefore, high-silicon ferrosilicon (or siliceous alloy) is a commonly used reducing agent in the production of low-carbon ferroalloys in the ferroalloy industry.
(4) 75# ferrosilicon is often used in the high-temperature smelting process of magnesium metal in the Pijiang process. Every ton of magnesium metal produced consumes about 1.2 tons of ferrosilicon, which plays a great role in the production of magnesium metal.
(5) Other uses. Ground or atomized ferrosilicon powder can be used as a suspended phase in the mineral processing industry.
(6) It can be used as a coating for welding rods in the welding rod manufacturing industry. High silicon ferrosilicon can be used in the chemical industry to make silicone and other products.
In addition, ferrosilicon powder can be used as a suspension phase in the mineral processing industry and as a coating for welding rods in the welding rod manufacturing industry. In the steelmaking industry, about 3 to 5 kg of 75% ferrosilicon is consumed for every ton of steel produced. Melting point: 75FeSi is 1300℃
