Introduction:
Silicon Aluminum Barium Calcium Alloy (Si-Al-Ba-Ca Alloy) As a premium-grade deoxidizer and desulfurizer in barium-based alloys, this compound significantly enhances steel purity and mechanical performance through advanced metallurgical reactions.
Core Advantages:
Oxygen & Sulfur Control：
Reduces oxygen content in molten steel to minimal levels (s10ppm), while forming complex oxides (CaO-BaO-SiOz-Al2Os) that rapidly float to the surface for efficient slag removal. Achieves dual-phase desulfurization: calcium reacts with sulfur to form Cas, and barium stabilizes residual sulfur in slag.
Steel Quality Enhancement：
Improves impact toughness by 15-25% and machinability by reducing non-metallic inclusions (e.g., MnS, Al2Os clusters).Enhances molten steel fluidity, reducing clogging incidents at tundish nozzles by 70%.
Process Optimization：
Specifically designed for BOF (Basic Oxygen Furnace) applications, with 30% faster deoxidation kinetics compared to traditional CaSi alloysLowers gas content (H2s1.5ppm, N2 S40ppm) and inclusion rating (ASTM s1.5).
