Abstract: The temperature gradient and liquid steel flow in the tundish of continuous casting in the vacuum induction melting process play an important role in the removal of solid inclusions, which directly affect the purity of liquid steel. Based on the analysis of the current situation of numerical simulation of temperature field, flow field and stress field coupling in continuous casting tundish, the numerical simulation of inclusion removal under multi-field coupling is summarized. The heat flow coupling, fluid solid coupling and fluid solid thermal coupling simulation methods are introduced. The numerical simulation of inclusion removal under fluid-thermostructure coupling is proposed. A reasonable combination of flow control devices and a selection of resistant materials can improve the quality of liquid steel.

Key words: vacuum, multi-field coupling, tundish, inclusion removal
