CFD Predictions for Mixing Times in an Elliptical Ladle Using Single- and Dual-Plug Configurations

Argon bottom stirring is commonly practiced in secondary steelmaking processes due to its positive effects on achieving uniform temperatures and chemical compositions throughout a steel melt. It can also be used facilitate slag metal refining reactions. The inter-mixing phenomena associated with argon gas injection through porous plugs set the efficiency summarized by evaluations of 95% mixing times. This study focuses investigating impact different plug positions ratios flow rates from two behavior within 110-tonne, elliptical-shaped industrial ladle. A quasi-single-phase modeling technique was employed for this purpose. CFD findings revealed that optimal position second placed diametrically opposite existing one at an equal mid-radius distance (R/2). An distribution yielded best results terms refractory erosion. comparative conducted between single- dual-plug-configured ladles based wall shear stresses using method. Furthermore, transient multiphase model developed examine formation open eyes (SOE) both dual-plug configurations volume fluid (VOF) model. indicated configuration outperformed current single-plug configuration.
