In the current research study, a mathematical model was developed to study the dissipation phenomena inside a new design of ladle shroud and its effects on flow patterns and inclusion removal rate. The New Ladle Shroud performance is evaluated in a conventional slab tundish, and the results are compared to different flow control arrangements. The velocity of the entry jet is decreased and the bulk flow is well controlled, the inclusion removal rate is improved, and compared to those arrangements where turbulence inhibitors are used.
