Applications
Steelmaking
Used as a deoxidizer and alloying agent, atomized ferrosilicon dissolves quickly in molten steel. It removes oxygen and non-metallic inclusions, improving steel purity. It also contributes essential alloying elements like silicon and iron for composition control.
Cast Iron Production
As an enhancing agent, it improves cast iron microstructure by refining graphite distribution, increasing strength, hardness, and wear resistance. It also reduces casting defects such as porosity and shrinkage.
Powder Metallurgy
A key raw material in powder metallurgy, it blends well with other metal/non-metal powders for sintered products. It enhances density, strength, and is ideal for magnetic materials, friction parts, and precision components.
Welding Rods
Used as a flux additive in welding rods, it acts as a deoxidizer, improving weld quality, strength, and corrosion resistance. It reduces weld defects like cracks and porosity, enhancing overall welding reliability.
