Discover the unmatched quality of our Ferrosilicon 70, 72, and 75 FeSi alloys. Perfectly designed as a reducing agent for ferroalloy production, ensuring superior performance and efficiency.
Ferrosilicon is a remarkable ferro alloy composed of iron and silicon, meticulously crafted from a blend of coke, steel scraps, and quartz or silica, smelted in an advanced electric furnace. Silicon's propensity to combine with oxygen to form silicon dioxide makes ferrosilicon an invaluable deoxidizer in steelmaking, generating significant heat to elevate molten steel temperatures during the process. This versatile alloy is also an essential additive, enhancing properties in low-alloy structural steel, spring steel, bearing steel, heat-resistant steel, and electrical silicon steel. Beyond its metallurgical prowess, ferrosilicon excels as a reducing agent in ferroalloy production and serves critical roles in the chemical industry.
