ABSTRACT

Liquid steel flow in continuous casting process has been recognized to be of great importance for the quality of the steel products. The down coming jet of metal from the ladle tends to induce turbulent and recirculatory motions in the tundish. These flows can play important role in non-metallic inclusions removal at the slag surface, thereby helping in the production of cleaner steel. Flow control devices such as dams and weirs help to modify the behaviour flow in the goal to enhance these objectives. The present work presents a numerical simulation of a turbulent diphasic flow which occurs during continuous casting process. The studied geometry of a one-strand tundish with molten steel flow and temperature distribution can be modified by using control devices as weirs and dams if it is needed. Different configurations are carried out to establish the interest of these control devices in the amelioration of inclusions decantation and temperature homogenization in the metal bath.
