Low Pollution Ferro Silicon 75/70 Fesi Essential Additives For Desulfurizing Agent
Ferrosilicon is an alloy composed primarily of iron (Fe) and silicon (Si). It is produced by smelting a mixture of iron ore, coke (carbon), and silica in an electric arc furnace. The silicon content in ferrosilicon can range from about 15% to 90%, depending on the intended application.
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
1.Steel production: Ferrosilicon is extensively used as an alloying agent in the production of steel. It introduces silicon and iron into the steel composition, improving its strength, hardness, and magnetic properties. It is particularly important in the production of stainless steel and specialty alloys.
2. Casting and foundry industry: Ferrosilicon acts as a deoxidizing agent and inoculant in the casting process. It helps remove impurities, such as oxygen, from molten metals, reducing the likelihood of defects in the final castings. Additionally, it controls the formation and distribution of graphite in cast iron, enhancing its mechanical properties.
3. Dense media separation: Ferrosilicon with specific densities is utilized in dense media separation processes. It acts as a medium to separate minerals based on their density differences. This process finds application in coal and mineral processing industries to separate valuable minerals from gangue materials.
