DESCRIPTION
FerroSilicon is commonly used as a deoxidizer in the steelmaking process. Deoxidation is a critical step in steelmaking that helps to remove impurities such as oxygen, sulfur, and other non-metallic elements from the molten steel. These impurities can negatively affect the final properties of the steel, such as strength, ductility, and machinability.
FerroSilicon is a ferroalloy made up of iron and silicon, with varying percentages of these two elements depending on the specific grade of FerroSilicon. When added to the molten steel, the silicon in FerroSilicon reacts with the oxygen and other non-metallic elements present in the steel, forming oxides that float to the surface of the molten steel and are removed as slag.
The amount of FerroSilicon added to the steel will depend on the specific application and desired properties of the final product. Typically, FerroSilicon is added in amounts ranging from 0.1% to 2% of the total weight of the steel. The exact amount of FerroSilicon required will depend on the initial oxygen content of the steel, as well as the specific deoxidation requirements of the steelmaking process.
In addition to its deoxidizing properties, FerroSilicon can also be used as an alloying agent in steelmaking. By adding silicon to the steel, the final product can have improved properties such as strength, hardness, and resistance to corrosion.
