Abstract：Based on the similarity principle， a water model of 1:3 has been established， a two strands slab continuous casting tundish of one iron and steel works was studied. Optimization experiment of hole size and location of dam was studied， it is concluded that， with the increase of the hole size， the average residence time first increases， then decreases， when hole size was about 90-120 mm， the average residence time was the longest； The average residence time and the proportion of dead zones of molten steel in tundish was influenced by the height of hole and the distance from hole to the bottom of dam， small hole height has advantage to the improvement of flow field； the average residence time of molten steel in tundish was not increased effectively when a small dam was added on the basis of retaining dam， but stagnation time of molten steel increase when the larger height small dam was added. When the optimized tundish was used， average residence time of molten steel in tundish increased by 40 sonds，and dead zone volume fell from 19.5% to 9.0% compared with prototype tundish.
