DESCRIPTION
Ferrosilicon 75 (FeSi 75) is an alloy made from a combination of iron and silicon. It typically contains 75% silicon and 25% iron by weight, although the exact composition can vary slightly depending on the specific manufacturing process.
Ferrosilicon 75 is primarily used as a deoxidizer and an alloying agent in the production of steel and other iron-based alloys. It is added to molten steel during the refining process to remove impurities and improve the strength and ductility of the final product. The silicon in ferrosilicon 75 also helps to control the grain size of the steel, which can affect its mechanical properties.
In addition to its use in the steel industry, ferrosilicon 75 is also used as a reducing agent in the production of magnesium and other metals. It can also be used as an inoculant in the production of cast iron, to promote the formation of graphite nodules and improve the mechanical properties of the final product.
Ferrosilicon 75 is typically produced in the form of lumps, powder, or briquettes, and is often transported in bulk or packed in bags for storage and shipment.
