Precision Refining for Specialty Alloys

Argon Oxygen Decarburization (AOD) is a secondary steelmaking process used to produce precise chemical compositions and specialty mechanical properties. After the initial melting phase, molten steel is transferred to an AOD vessel, where controlled refining allows steelmakers to reduce carbon levels while maintaining critical alloying elements essential for product performance.

Advanced Decarburization and Secondary Refining

During the AOD process, oxygen, argon, and nitrogen are injected into the molten steel to remove carbon while minimizing oxidation of valuable alloying elements. Flux materials, including lime, are introduced to promote sulfur removal and capture impurities, which ultimately results in cleaner steel and greater consistency throughout the refining process.
