Silicon Aluminum Barium Calcium Alloy

Silicon aluminum barium calcium alloy can replace silicon aluminum barium alloy and part of silicon aluminum, silicon calcium, calcium aluminate, aluminum wire, etc., further reducing alloying costs. Silicon-aluminum-barium-calcium can fully improve the deoxidizing ability of calcium and promote the spheroidization and denaturation process of non-metallic inclusions. Its deoxidation can make the total oxygen content of the steel billet between 9-15ppm; compared with aluminum-based deoxidizers, it can reduce the inclusions in the steel by about 75-80%; it can refine the ferrite grains, Improve the impact toughness and processing performance of steel, improve the fluidity of molten steel, and prevent nozzle blockage.
