| Abstract Scope |
A numerical simulation of the ladle–shroud–tundish system is developed to analyze the effect of shroud clogging on the fluid dynamics pattern, thermal behavior, and inclusion removal. The thermal stratification of steel in a 150-ton ladle is analyzed during the holding period; subsequently, the ladle is emptied into the tundish, and two scenarios are considered: the first with the shroud free of obstruction and the second with the shroud partially clogged. Finally, alumina particles are added into the tundish once the quasi-steady state is reached, and their trajectories are simulated using the discrete phase model. The results show that clogging completely modifies the fluid dynamics and temperature distribution in the tundish, decreasing its efficiency for inclusion removal by 25% for particles of 10 μm. |
