Ferrosilicon 3-8mm refers to the size range of ferrosilicon alloy particles from 3mm to 8mm. Ferrosilicon is an alloy composed of iron and silicon.

Ferrosilicon 3-8mm Features

Slower dissolution rate: Compared with smaller size ferrosilicon, 3-8mm ferrosilicon dissolves slower in molten metal. This is particularly important in processes that require slow release of silicon.

Lower dust generation: Compared with smaller size ferrosilicon, larger size can reduce dust generated during transportation and operation, improving the working environment.

Ferrosilicon 3-8mm Uses

1,Deoxidizer:

Ferrosilicon granules as deoxidizers can effectively reduce the oxygen content in molten steel and improve the purity and quality of steel.

2,Alloy additives:

The silicon and iron in ferrosilicon granules can form alloy phases with carbon and other elements in steel, adjust the chemical composition of steel, and improve the mechanical properties of steel.

3,Manganese-silicon alloy raw materials:

FeSi granules also contain an appropriate amount of manganese, which can be used as one of the raw materials for preparing manganese silicon alloys.
