Why is the silicon-barium alloy an efficient choice for your steelmaking and casting processes?

1. Exceptional Deep Deoxidation: Barium has a much higher affinity for oxygen than silicon or aluminum, forming low-melting-point composite oxides (BaO·SiO₂) that float to the surface and are easily removed. Total oxygen in molten steel can be reduced to below 15 ppm, achieving 40%–50% higher deoxidation efficiency than ferrosilicon, resulting in finer and purer inclusions.

2. High-Efficiency Desulfurization + Slag Modification: Simultaneous desulfurization reduces sulfur content, improves inclusion morphology, minimizes white spots and cracks in steel, and enhances steel toughness and fatigue strength.

3. Long-lasting inoculation (for casting): With decay resistance more than twice that of 75% ferrosilicon, it provides prolonged inoculation effectiveness, reduces white cast iron, refines graphite, and improves spheroidization rates. It ensures uniform cross-sections in thick, large castings and delivers superior machinability.

4. Low Dosage and Cost-Effective: The dosage per ton of steel or iron is 30%–50% lower than that of ferrosilicon, reducing smoke and dross, improving yield, and resulting in lower overall costs.
