Tailored Silver Gray Silicon Barium Calcium Alloy for the Steelmaking Industry
Calcium silicon alloy, an intricate compound of silicon, calcium, and iron, stands as an exceptional deoxidizer and desulfurization agent. This versatile alloy can replace aluminum for final deoxidation, making it indispensable in the production of high-quality steel, special steel, and various specialized alloys, such as rail steel, low carbon steel, stainless steel, steel for nickel-base alloys, and titanium alloys.
Calcium Silicon Alloys serve as superior deoxidizers and desulfurizers in high-grade steel manufacturing. Both Calcium and Silicon exhibit a robust chemical affinity for oxygen, with Calcium additionally showing strong affinities for sulfur and nitrogen. The steel industry utilizes about 90% of the global CaSi consumption, highlighting its critical importance.
This alloy also plays a pivotal role in modifying non-metallic inclusions. Calcium Silicon is instrumental in controlling the shape, size, and distribution of oxide and sulfide inclusions, thereby enhancing the fluidity, machinability, ductility, and impact properties of the steel products.
