Study on the Effect of Long Shroud Structure on Molten Steel Flow in Single Strand Tundish by Numerical Simulation

In this paper, a single strand tundish is taken as the research object, and a three-dimensional mathematical model is established to analyze the effect of the long shroud structure on the flow field, temperature field, pressure field, and inclusions trajectories of molten steel in the tundish. The fluid flow patterns in the tundish are analyzed by comparing the residence time distribution curves of the four types of long shrouds: traditional long shroud vortex long shroud, dissipative long shroud, and trumpet-shaped long shroud. At the same time, the effects of different long shroud structures on the fluctuation of free surface are compared. The reasonable long shroud structure is conducive to obtaining uniform molten steel and provides theoretical guidance for actual production.
