Product Introduction
Ferro Silicon 72 is a ferroalloy product with a silicon content of not less than 72%. It is made from high-quality silica and coke as the main raw materials and is produced by high-temperature reduction smelting in an electric arc furnace.
Main Functions
Steelmaking Deoxidation and Alloying: Rapidly reduces the oxygen content in molten steel, decreases non-metallic inclusions, and improves the purity, strength, and mechanical properties of the steel.
Cast Iron Inoculation Treatment: Promotes graphite precipitation and uniform distribution, improves the microstructure of castings, and enhances casting strength and machinability.
Magnesium Reducing Agent: Widely used in the Pidgeon process for magnesium smelting, improving reduction reaction efficiency and magnesium recovery rate.
