Product Introduction
Ferro Silicon (FeSi) is a ferroalloy composed primarily of iron (Fe) and silicon (Si), typically containing Silicon content ranging from 15% to 90%, with the most common grades being FeSi 65%, 72%, and 75%. This alloy is produced by reducing silica (SiO₂) in the presence of iron using electric arc furnaces.
Ferro Silicon is an essential material used extensively in the iron and steel industry as a deoxidizer, alloying agent, and reducing agent. Its ability to improve the properties of steel and cast iron makes it indispensable in various metallurgical applications.
Specification
Key Features & Benefits
✅ Excellent Deoxidizing Power
Silicon in FeSi reacts strongly with oxygen to form stable silicon dioxide (SiO₂), which removes oxygen from molten steel, enhancing steel purity and quality.
✅ Improved Steel Strength & Hardness
Adding FeSi to steel enhances tensile strength, hardness, and elasticity, making it suitable for demanding structural applications.
✅ Increases Fluidity in Cast Iron
In foundries, FeSi promotes the formation of graphite and improves molten metal flowability, leading to better castability and smoother surfaces.
✅ Reduces Shrinkage Defects
Enhances uniform solidification during cooling, reducing porosity and shrinkage in castings.
✅ Thermal Stability
FeSi has excellent heat resistance, making it suitable for high-temperature operations and refractory applications.
✅ Corrosion & Oxidation Resistance
Silicon increases resistance to oxidation and corrosion, especially in stainless and specialty steels.
