Ferrosilicon, a remarkable ferro alloy, is a fusion of iron and silicon. Crafted meticulously from coke, steel scraps, and quartz (or silica) in an electric furnace, this alloy exemplifies top-tier quality. Silicon's natural affinity to bond with oxygen to form silicon dioxide positions Ferrosilicon as an essential deoxidizer in steelmaking. This process not only purges oxygen but also elevates molten steel temperatures due to the exothermic reaction of SiO2 formation. Furthermore, Ferrosilicon serves as a vital alloying element additive, finding extensive applications across low-alloy structural steel, spring steel, bearing steel, heat-resistant steel, and electrical silicon steel. It also functions as a key reducing agent in the realms of ferroalloy production and the chemical industry.
