Applications
Carbon Steel Production – Used during secondary refining to reduce oxygen content and improve steel cleanliness.
Alloy Steel Manufacturing – Assists in deoxidation and inclusion modification to support stable mechanical properties.
Continuous Casting Plants – Improves molten steel quality and helps reduce casting-related defects.
Steel Foundries – Applied during molten metal treatment to enhance casting quality and reduce non-metallic inclusions.
Special Steel Production – Suitable for refining processes requiring controlled deoxidation and cleaner steel.
Production & Quality Assurance
Production Process
Raw materials are selected and inspected according to chemical composition requirements.
Calcium, barium, silicon, and aluminum are proportioned based on the target alloy grade.
The charge is melted and alloyed in an electric furnace under controlled process conditions.
The molten alloy is cast and cooled into ingots or blocks.
Products are crushed and screened into the required particle sizes.
Finished products are packaged after inspection and prepared for shipment.
