This work shows the numerical simulation results of liquid steel flow in three strand tundish designed for the continuous bloom casting process. The authors proposed the modification of ladle shroud by expanding-compressing-expanding system at the end of ladle shroud. The considered ladle shroud modification consisted on the decrease momentum of the liquid steel feeding stream. The aim of the research was checked the influence of ladle shroud immersion depth in liquid steel on hydrodynamic structures in the three strand tundish based on the E and F-type residence time distribution curves. Furthermore, the flow and temperature fields of liquid steel were considered too. The research results allowed to assess the appropriate the modified ladle shroud depth in a liquid steel according to the amount of active and stagnant liquid steel flow volume. The transition zone during the sequential casting process was established for every research cases. Also, the factor of asymmetrical liquid steel flow in the tundish was checked based on the residence time distribution curves. The computer calculations were performed in the Ansys-Fluent computer program.Keywords: Continuous steel casting, tundish, ladle shroud, numerical simulation, liquid steel flow
