Premium Silver Gray Silicon Barium Calcium Alloy for the Steelmaking Industry
Calcium Silicon Alloy is a sophisticated compound composed of silicon, calcium, and iron, making it an exceptional deoxidizer and desulfurization agent. Currently, calcium alloy can replace aluminum for final deoxidation and is crucial in the production of high-quality steel, specialty steels, and unique alloys. This includes applications in rail and low-carbon steel, stainless steel, nickel-base alloy, titanium alloy, and other specialized alloys.
Calcium Silicon Alloys serve as vital deoxidizers and desulfurizers in manufacturing premium-grade steel. Both calcium and silicon exhibit strong chemical affinities for oxygen. Particularly, calcium's robust chemical affinity extends to oxygen, sulfur, and nitrogen. The steel industry utilizes around 90% of global CaSi consumption due to its essential role in steel production.
This alloy also plays a pivotal role in modifying non-metallic inclusions. By using Calcium Silicon, the shape, size, and distribution of oxide and sulfide inclusions are managed, enhancing the steel's fluidity, machinability, ductility, and impact properties, thereby significantly improving product performance.
