Tailor-Made Silver Gray Silicon Barium Calcium Alloy for the Steelmaking Industry Alloy
Calcium silicon alloy, an exceptional compound of silicon, calcium, and iron, serves as an ideal deoxidizer and desulfurization agent. This alloy effectively replaces aluminum in final deoxidation processes and is crucial for the production of high-quality steel, specialty steels, and unique alloys. Its applications span across rail steel, low carbon steel, stainless steel, and advanced alloys like nickel and titanium-based alloys.
Calcium Silicon Alloys are paramount in high-grade steel manufacturing as deoxidizers and desulfurizers. Both calcium and silicon exhibit a strong affinity for oxygen, with calcium also showing a high affinity for sulfur and nitrogen. The steel industry is the largest consumer of CaSi, accounting for approximately 90% of global consumption.
This versatile alloy is also instrumental in modifying non-metallic inclusions. By controlling the shape, size, and distribution of oxide and sulfide inclusions, Calcium Silicon enhances the fluidity, machinability, ductility, and impact properties of steel products.
