70/45 Fesi Ferro Silicon Lump For Steelmaking Deoxidizer
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.
The silicon content in ferrosilicon can range from about 15% to 90%, depending on the specific application. The higher the silicon content, the greater the deoxidizing capacity of the alloy. Additionally, the alloy can contain small amounts of other elements such as calcium, aluminum, and manganese, which can further modify its properties.
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.
