The importance of proper melt flow in continuous casting tundish for production of clean steel was well recognized, more in-depth research melt flow by physical models can promote tundish metallurgy effect and improve the quality of liquid steel. Based on the requirements of Re number and Fr number similar on the same time in the continuous casting water simulation, a synthetical hydraulic simulation platform of continuous casting was established. Flow characteristics with velocity field, vorticity field, RTD in extra thick slab tundish were got by the platform using NI image processing and PIV. The results showed that flow in the tundish had larger turbulent eddies, which formed a similar "funnel" vortex structure in inlet section of the tundish. Flow brought two big circulations in the exit section because of the channel and had a great impact on the side walls. RTD with noncontact measurement was coincident with the results of numerical simulation, longer residence time and larger dead volume showed the necessity of heating for the tundish.
