Abstract

Multiphase fluid flow and particle motion in the submerged entry nozzle (SEN) and the mold of the slab continuous caster at Panzhihua Steel were analyzed using water models, numerical simulations and industrial measurements. The effects of SEN geometry, submergence depth, mold width, casting speed and gas flow rate were investigated. Numerical simulation showed that on occasion, even large bubbles can penetrate deeply and be entrapped through the bottom outlet. Mass balances of inclusions in the steel slag from slag and slab measurements showed that around 20% inclusions are removed from the steel into the mold slag.
