Abstract In order to study the effect of channel on flow field in tundish， a research on fluid flowing status and heat transport in a two-strand slab continuous casting with different structure was carried out by using a water model and mathematical model. The results show that the plug flow area in the original tundish was 26.33% only with turbulence inhibitor， wall and dam， and the dead area was up to 17.94%. The effect of optimization was obvious after using the channel filter instead of the dam. Compared with the original tundish， the average resident time of molten steel in the optimized tundish increased from 243.68 to 262.50 s， the dead area fell from 17.94% to 9.11%， and the temperature of outlet was only 2 ℃ lower than that in the original one. It can not only make the operation easier， but also reduce the cost. Field experiment results shows that after 10 heats， there were 19 kg white solid absorpted on the channel of the filter， so the amount of inclusions in liquid steel decreased considerably， and it’s beneficial to improve the quality of continuous cast slab.

Key words： tundish math modeling water modeling channel filter flow field
