Si-Al-Ba-Ca Alloy

Ferro Silicon Aluminum Barium Calcium is a versatile composite deoxidizer, desulfurizer, and alloy additive. It combines the advantages of silicon, aluminum, barium, and calcium, delivering exceptional performance in molten steel purification, inclusion morphology control, and alloying. It is a key material for producing clean steel and high-quality special steels.

Produced by the electrosilicothermic method: precisely proportioned raw materials including silica, bauxite, barite, and limestone are mixed and smelted at high temperatures in a submerged arc furnace. The molten alloy is cast, cooled, and crushed into standard sizes (10-50mm), with strict quality control throughout the process.

​​ Powerful deoxidation and desulfurization capabilities significantly reduce oxygen and sulfur content.

Transforms harmful inclusions (e.g., Al₂O₃) into low-melting-point, spherical calcium aluminates that are easy to float and remove.

Barium improves the stability and utilization of calcium, leading to better alloying effects.

Remarkably improves comprehensive properties like impact toughness and fatigue strength.

​High-Quality Steelmaking:​​ Ideal for grades like pipeline steel, bearing steel, and gear steel, which demand ultra-high fatigue strength and purity. It effectively modifies inclusions, enhancing toughness and service life.

Used in LF, CAS-OB, and other refining processes for deep deoxidation/desulfurization and precise composition control.

Acts as a highly efficient inoculant, significantly improving graphite morphology and increasing the strength and uniformity of iron castings.
