Production Process
Ferro Silicon Aluminum Barium is typically produced by a submerged arc furnace process. Raw materials like quartz, bauxite, barite (BaSO₄), coke, and iron scraps are blended in precise ratios and smelted in a high-temperature electric furnace via a carbothermal reduction reaction. The alloy is then cast and crushed into specified sizes.
Key Features
Deep Deoxidation: Barium significantly reduces oxygen potential, with better deoxidation capability than ferro silicon aluminum.
Synergistic Desulfurization: Aluminum and barium work together to provide effective desulfurization.
Molten Steel Purification: Deoxidation products are low-melting-point composite oxides, easy to float and remove.
Cost Savings: Can replace multiple single deoxidizers, offering lower comprehensive cost.
Applications
High-Quality Steelmaking: Used for deep deoxidation in bearing steel, gear steel, and other quality steels.
Stainless Steel Refining: Applied in AOD/VOD refining processes for final deoxidation.
Special Steel Production: Improves steel cleanliness and enhances mechanical properties.
Foundry Industry: Used for molten iron treatment in high-end castings.
FAQ
Q: What are the packaging and storage requirements?
A: It is usually packed in 1-ton bags or 25/50kg woven bags with moisture-proof liners. Store in a dry, well-ventilated place to prevent dampness.
Q: What is the common barium content range?
A: The barium content typically ranges from 4% to 30%. The ratios of Si, Al, and Ba can be customized to meet specific requirements.
