Customized Silver Gray Silicon Barium Calcium Alloy for Exceptional Steelmaking Performance
Calcium Silicon alloy, a sophisticated blend of silicon, calcium, and iron, stands as the ultimate compound deoxidizer and desulfurization agent. Its versatility allows it to replace aluminum for final deoxidation, making it indispensable in the production of high-quality steel, special steel, and unique alloys. Applications range from rail and low carbon steel to stainless steel, nickel-base alloys, titanium alloys, and other specialized variants.
Calcium Silicon Alloys play a pivotal role as deoxidizers and desulfurizers in the manufacturing of premium-grade steel. The inherent strong chemical affinity of Calcium and Silicon for oxygen is unparalleled. Notably, Calcium's robust affinity extends to sulphur and nitrogen, making it invaluable. The global steel industry relies heavily on CaSi, with approximately 90% of global consumption attributed to this sector.
Additionally, this alloy is instrumental in modifying non-metallic inclusions. Calcium Silicon expertly controls the shape, size, and distribution of oxide and sulfide inclusions, thereby enhancing the fluidity, machinability, ductility, and impact properties of steel products.
