Superior Customized Silver Gray Silicon Barium Calcium Alloy for the Steelmaking Industry
Our Calcium Silicon Alloy, a meticulously engineered compound of silicon, calcium, and iron, serves as an exceptional deoxidizer and desulfurization agent. In modern steelmaking, it supersedes aluminum for final deoxidation, crucial for producing high-quality steel and special alloys, including rail steel, low carbon steel, stainless steel, nickel-based alloys, and titanium alloys.
Calcium Silicon Alloys excel as a deoxidizer and desulfurizer in high-grade steel manufacturing, thanks to the strong chemical affinities of calcium and silicon. Especially notable is calcium's affinity not only for oxygen, but also for sulfur and nitrogen. The steel industry consumes about 90% of the global CaSi production.
This alloy is invaluable for modifying non-metallic inclusions. It allows for precise control over the shape, size, and distribution of oxide and sulfide inclusions, thereby enhancing the fluidity, machinability, ductility, and impact properties of steel products.
