Customized Silver Gray Silicon Barium Calcium Alloy for Premium Steelmaking Applications
Calcium Silicon Alloy is a meticulously engineered compound consisting of silicon, calcium, and iron, serving as an unparalleled deoxidizer and desulfurizer. Currently, calcium alloy is an excellent alternative to aluminum for final deoxidation, especially in producing high-quality steel, special steel, and specialized alloys such as rail steel, low carbon steel, stainless steel, steel-nickel base alloys, and titanium alloys.
Calcium Silicon Alloys are pivotal in the steel industry as deoxidizers and desulfurizers, essential for manufacturing high-grade steel. Both calcium and silicon exhibit a robust chemical affinity for oxygen. Notably, calcium also has a pronounced affinity for sulfur and nitrogen, making it indispensable in the steel industry, which consumes around 90% of global CaSi production.
This alloy plays a crucial role in modifying non-metallic inclusions. Calcium Silicon is instrumental in controlling the shape, size, and distribution of oxide and sulfide inclusions, thereby enhancing the fluidity, machinability, ductility, and impact properties of the steel.
