Discover the superior qualities of Ferrosilicon 70%, 72%, and 75% FeSi Ferro Silicon, the ideal choice for a reducing agent in ferroalloy production. These exceptional grades of ferrosilicon are the backbone of efficient and effective metallurgical processes.
Ferrosilicon stands as an essential ferroalloy, skillfully crafted from a fusion of iron and silicon. This remarkable alloy is produced through a meticulous process involving coke, steel scraps, and quartz (or silica) that is smelted in an advanced electric furnace. With silicon's affinity for oxygen forming silicon dioxide, ferrosilicon becomes a critical deoxidizer during steelmaking, efficiently removing unwanted oxygen. The exothermic creation of SiO2 also serves to significantly increase the temperature of molten steel, enhancing the process. Beyond deoxidation, ferrosilicon serves as a valuable alloying element additive, finding widespread application in the production of low-alloy structural steel, spring steel, bearing steel, heat-resistant steel, and electrical silicon steel. Additionally, ferrosilicon excels as a reducing agent in ferroalloy production and various chemical industry applications.
