INFLUENCE OF IMMERSION DEPTH OF LADLE SHROUD IN LIQUID STEEL ON RANGE OF THE TRANSITION ZONE FOR ONE-STRAND TUNDISH DURING CONTINUOUS CASTING OF STEEL

This article presents the results of computer simulation of the flow of liquid steel through one-strand tundish. In paper was examined four immersion depth of ladle shroud in liquid steel. The simulation was performed for sequence of slabs casting. The effect of calculations were a residence time distribution curves (RTD), type (F). Based on the distribution curves range of the transition zone for the different variants of the immersion depth of ladle shroud were estimated. Based on the results of numerical calculations, it was found that increase the immersion depth of ladle shroud in liquid steel influences on the range of transition zone. For numerical simulation of the flow of liquid steel Ansys-Fluent program were used.
