Thermofluid Behavior During Post‐VD Soft Argon Stirring of X80 Pipeline Steel: Coupled Modeling and Industrial Validation

Postvacuum degassing (VD) soft argon stirring controls temperature homogenization and interfacial stability during clean steel refining. A 3D transient coupled flow and heat‐transfer model was developed for a 210 t ladle during post‐VD soft stirring of X80 pipeline steel. Four qu...
