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).

Recommended Applications:
1.Primary Steelmaking: BOF/LD converter deoxidation.
2.Secondary Refining: Ladle furnace treatment for ultra-low sulfur steel (S s0.005%).
3.Continuous Casting: Prevents nozzle clogging and improves slab surface quality.
Block shape, particle size is controlled between 10~200mm, and the fragmentation rate is less than 5%. Other common particle sizes include: 0-1mm, 1-3mm, 3-10mm, 10-50mm, 50-100mm, etc.
