Abstract：Working on experiment platform for hydraulic model of continuous castings based on PXI technology， the 1∶2 tundish water model was applied in studying the influence of weir dam and porous retaining wall on the flow of 180mm×240mm six- strand billet tundish in one steel plant, and the relevant experimental conclusions were made by analyzing the flow field of relevant area and residence time distribution curves(RTD) in different tundishes. Experimental results showed that the uniformity of flow was bad in the injection flow region of tundish without weir dam or porous retaining wall, and its response time(7s) and peak time（224s）were shorter. The flow properties in the tundish became much better after optimization, and the response time and peak time were extended to 99 and 159s, respectively. Besides, the dead volume reduced by 45.71%, and the piston flow volume increased from 12.03% to 25.47%.
