Water Model Experiment on Optimization of 5-strand Billet Tundish Internal Shape

Based on approximation principle,by means of using water model experiment,the flow field and flow distributing in the tundish of the 5-strand are studied.By researching U-shaped wall of the tundish,and adjusting the angle and the position of the opening holes in the tundish to control flowing mode of the fluid,the best project can be got.When the velocity magnitude of the flowmeter is 1.0 m3/h,the volume of dead zone is reduced by 14.7%,and at the same time,the minimum retention time for the hot metal comes up to 26 s and the average time to 257.6 s.
