What is ferrosilicon?
Ferrosilicon is an iron alloy composed of iron and silicon. Ferrosilicon is an iron silicon alloy made by smelting coke, steel shavings, quartz (or silica) as raw materials in an electric furnace;
The use of ferrosilicon:
1. Ferrosilicon is an essential deoxidizer in the steelmaking industry. In steelmaking, Silicon ferro is used for precipitation deoxidization and diffusion deoxidization. Brick iron is also used as an alloying agent in steelmaking.
2. Used as an inoculant and spheroidizer in the cast iron industry. In the production of ductile iron, silicon ferro 75 is an important inoculant (helping to precipitate graphite) and spheroidizing agent.
3. Used as a reducing agent in ferroalloy production. Not only is the chemical affinity between silicon and oxygen high, but the carbon content of high silicon silicon ferro is also very low. Therefore, high silicon silicon ferro (or siliceous alloys) is a commonly used reducing agent in the production of low-carbon ferroalloys in the ferroalloy industry.
