Customized Silver Gray Silicon Barium Calcium Alloy for the Steelmaking Industry
Our premium Calcium Silicon Alloy is a meticulously crafted compound alloy composed of silicon, calcium, and iron. Renowned as a top-tier deoxidizer and desulfurization agent, this alloy is an outstanding alternative to aluminum for final deoxidation. It is extensively utilized in the production of high-quality steel, special steel, and specialized alloys, including rail steel, low carbon steel, stainless steel, nickel-based alloys, and titanium alloys.
Calcium Silicon Alloys are indispensable as deoxidizers and desulfurizers in high-grade steel manufacturing. Both Calcium and Silicon exhibit an exceptional chemical affinity for oxygen. Notably, Calcium also demonstrates a robust affinity for sulphur and nitrogen. The steel industry contributes to approximately 90% of global CaSi consumption, highlighting its critical role.
This versatile alloy is also pivotal in modifying non-metallic inclusions. Calcium Silicon is expertly employed to control the shape, size, and distribution of oxide and sulfide inclusions, significantly enhancing the fluidity, machinability, ductility, and impact properties of the steel products.
