Industrial-Grade Ferro Silicon 75 Alloy Lump
With approximately 75% silicon content, this material enhances the mechanical strength, hardness, and heat resistance of steel and cast iron while maintaining superior metallurgical purity.
Refining Function and Industrial Application Value of FeSi75
FeSi75 Alloy is produced by melting quartzite, coke, and steel scrap in high-power electric furnaces under strict process control.
During steel refining, silicon reacts with oxygen to form stable oxides, significantly reducing inclusions and improving the fluidity of molten metal.
This alloy also serves as an efficient thermal agent during ingot capping, where it releases controlled heat to stabilize solidification and improve recovery rates.
In the casting industry, FeSi75 is used as an inoculant and nodulizer for gray and ductile iron, optimizing graphite structure and ensuring better surface quality and machinability.
Because of its strong reduction characteristics, it is also used in producing low-carbon ferroalloys and magnesium extraction processes, providing energy efficiency and consistency.
