Ferrosilicon is an ferro alloy composed of iron and silicon. The color of ferro silicon is gray.
According to the content of Si, Fe, Al, etc., it is divided into
different grades. The most widely used is 75% ferrosilicon. In the steelmaking industry, about 3-5 kg of 75% ferrosilicon
is consumed for every 1 t of steel produced.

Ferro silicon uses
Mainly used in the steel industry and foundry industry.
- Used as a deoxidizer and alloying agent in the steelmaking
industry.
To get qualified steel, deoxidation must be carried out in the
final stage of steelmaking. The chemical affinity between silicon
and oxygen is very high. So, ferrosilicon is a strong deoxidizer for steelmaking.
- Used as an inoculant and spheroidizing agent in the cast iron
industry.
- Used as a reducing agent in low carbon iron alloys.
