What is ferro silicon

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 has two kinds of blocks and powders. Common particle sizes are 0-3mm, 10-60mm, 10-100mm, etc. Manufacturers and suppliers can be customized according to user requirements.

Ferro silicon manufacturing process

The raw materials of ferrosilicon are coke, steel scrap, quartz (or silica) and the like. Smelted in an electric furnace.

Ferrosilicon is used frequently in steel making. This is because silicon reacts with oxidation to produce SiO2. Therefore, ferrosilicon can be used as a deoxidizer. At the same time, when SiO2 is formed, a large amount of heat is released. This is beneficial to increase the temperature of the molten steel.

Ferro silicon uses

Mainly used in the steel industry and foundry industry.

1. 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.

2. Used as an inoculant and spheroidizing agent in the cast iron industry.

3. Used as a reducing agent in low carbon iron alloys.
