Product Processing
How to produce Ferrosilicon?
The primary raw materials used in the production of FeSi are iron ore, coke, and silica. Iron ore is used as the source of iron, and coke and silica are used as reducing agents. The quality of these raw materials plays a significant role in the quality of the final product.

Application
1. Ferrosilicon is an essential deoxidizer in the steelmaking industry.
In steelmaking, ferrosilicate is used for precipitation deoxidation and diffusion deoxidation. Brick iron is also used as an alloying agent in steelmaking.
2. Ferrosilicon is used as an inoculant and spheroidizer in the cast iron industry.
In the production of ductile iron, ferrosilicon is an important inoculant(to help precipitate graphite) and spheroidizer.
3. Ferrosilicon used in ferroalloy production.
Ferrosilicon 75 is often used in the high-temperature smelting process of metallic magnesium in the Pidgeon process to replace the magnesium in CaO or MgO. Every ton of metallic magnesium produced consumes about 1.2 tons of ferrosilicon.
