Composition Of Ferrosilicon And Its Uses

Ferrosilicon, or the alloy ferrosilicon, is an alloy synthesized from the melting of pure silicon and iron. The silicon content in ferrosilicon is between 70% and 75%, while the iron content is between 20% and 25%, and the content of other elements is usually less than 5%.

Description

the production process of ferrosilicon

Ferrosilicon is a very important metallurgical raw material, which can be widely used in iron and steel metallurgy, foundry and chemical industry.

The production of ferrosilicon is usually made using the ironmaking process, which mainly includes the following steps:

1. Screening: The selected raw materials such as quartz sand, manganese ore, and pulverized coal will be screened.

2. Mixing: Mix the screened raw materials evenly in a certain proportion.

3. Smelting: Put the mixed raw materials into the furnace for high-temperature smelting, and add a certain amount of calcium oxide for desulfurization.

4. Separation: The molten ferrosilicon is separated through the separator to obtain a pure ferrosilicon alloy.

5. Cooling: The separated ferrosilicon alloy is cooled before packaging and selling.
