Deoxidizer Ferro Silicon 65/70/72 Fesi Essential Additives
Ferrosilicon is an alloy composed primarily of iron (Fe) and silicon (Si). It is produced by melting a mixture of iron ore, silicon dioxide, and coke or charcoal in an electric arc furnace. The resulting alloy is commonly used as a deoxidizer and an alloying agent in the production of steel, as well as in other industrial applications.
Ferro Silicon Function
Desulfurizing agent: In some instances, ferrosilicon can be utilized as a desulfurizing agent. It reacts with sulfur present in molten metal, forming a slag that can be removed, thereby reducing the sulfur content in the final product.
Alloying element: Ferrosilicon is added to steel and iron to introduce silicon as an alloying element. This addition can enhance the material's strength, hardness, and magnetic properties. It is commonly used in the production of stainless steel, electrical steel, and other specialty alloys.
Deoxidizer: Ferrosilicon is commonly used as a deoxidizing agent in the production of steel and cast iron. It reacts with oxygen and other impurities present in the molten metal, reducing them and preventing the formation of defects in the final product.

Product Applications
Ferrosilicon has various applications in different industries. Some of its key applications include:
1. Steel Production: Ferrosilicon is extensively used in the steelmaking process as a deoxidizer and alloying agent. It helps remove impurities like oxygen, sulfur, and phosphorus from molten steel, improving its quality and properties. It also enhances the strength, hardness, and corrosion resistance of steel.
2. Cast Iron Production: Ferrosilicon is utilized in the production of cast iron. It improves the fluidity and castability of the molten metal, making it easier to pour into molds and shape into desired forms.
