Based on the research prototype of an 18t tundish for three-strand unsymmetrical casting 250 mm X 280 mm bloom at Xining Special Steel
the effect of 3 kinds of flow control device on flow field of liquid in tundish is studied by using geometric similarity ratio 1: 2. 2 water model to get optimum new type baffle. Results show that the difference of average residence time and minimum residence time between tundish three strand nozzles in prototype tundish is bigger
it is unfavorable to uniformly control each strand casting; with using the optimum new U-type baffle
dead volume fraction of liquid in tundish decreases by 36. 6% and the standard deviation of average residence time of three nozzle decreases
it is favorable to uniformly control each strand casting.
