| Abstract Scope |
This study analyzed the effect of implementing a nozzle with torsion channels during bottom stirring in the ladle furnace, a key operation for achieving chemical and thermal homogenization of the bath during secondary refining. A multiphase steel–slag–argon–air model was employed, using the Volume of Fluid (VOF) approach for interface tracking. The results show that the injection configuration has a significant impact on the flow distribution. The dual injection setup exhibited the best performance, with a reduction in mixing time of 41% and 36% compared to the single injection configurations at 3/4 and 2/3 of the ladle radius, respectively. Additionally, this configuration generated the highest shear stresses distributed throughout the ladle. The 3/4 radius injection concentrated shear stress in the slag layer, while the 2/3 configuration redirected it toward the refractory walls, revealing distinct fluid–refractory interaction patterns. |
