Premium Customized Silver Gray Silicon Barium Calcium Alloy for the Steelmaking Industry
Calcium silicon alloy, an exceptional compound alloy consisting of silicon, calcium, and iron, serves as an ideal deoxidizer and desulfurization agent. Presently, this remarkable calcium alloy can replace aluminum for final deoxidation, and is essential in producing high-quality steel, special steel, and unique alloys. These applications include rail and low carbon steel, stainless steel, and specialized alloys like steel-nickel base, titanium alloys, and other specialty alloys.
Calcium Silicon Alloys are the quintessential deoxidizer and desulfurizer in manufacturing high-grade steel. Both calcium and silicon have an extraordinary chemical affinity for oxygen, with calcium also demonstrating a strong affinity for sulphur and nitrogen. The steel industry utilizes around 90% of global CaSi consumption, signifying its critical importance.
This alloy is indispensable for modifying non-metallic inclusions. Calcium Silicon controls the shape, size, and distribution of oxide and sulfide inclusions, enhancing fluidity, machinability, ductility, and impact properties of steel products.
