Product Description
Low Impurities High Purity Ferro Silicon FeSi 72/70 Ferrosilicon For Cast Iron
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.
Ferrosilicon is used in the steelmaking industry as a deoxidizer and alloying agent, and ferrosilicon is used in the foundry industry as an inoculant and spheroidizing agent.
Function
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.

Applications
Ferrosilicon has various applications in different industries. Some of its key applications include:
- 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.
- 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.
- Improving the shape of inclusions and reducing the content of gas elements in molten steel is an effective new technology to improve steel quality, reduce costs, and save iron.
