DESCRIPTION
FerroSilicon is commonly used in the steelmaking process as an additive to improve the quality and performance of the final product. It is added to molten steel during the refining stage to help remove impurities and improve the steel’s properties.
One of the primary benefits of using FerroSilicon in steelmaking is that it can act as a deoxidizer, helping to remove impurities such as oxygen and sulfur from the molten steel. This results in a cleaner and more homogeneous mixture, which can improve the fluidity and casting properties of the steel.
FerroSilicon is also commonly 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. Additionally, FerroSilicon can be used to improve the magnetic properties of the steel, making it useful in applications such as electrical transformers.
The exact amount of FerroSilicon added to the steel can vary depending on the specific application and desired properties of the final product. Typically, FerroSilicon is added to the steel in amounts ranging from 0.1% to 1.5% of the total weight.
