Abstract：Fluid flow in the tundish was one of the key factors to affect the slab quality. In order to decrease the difference of fluid flow between two strands, water model method and numerical simulation method were applied to investigate the fluid flow character in an asymmetric two-strand tundish. Exermental results show that there are greater difference of fluid flow between two strand in the tundish with straight shroud,circular turbulent inhibitor and single dam. But by using shroud with side-hole and multi-hole baffle, the difference of the anerage residue time between two strands is only 3/4 of that in the tundish with straight shroud, circular turbulent inhibitor and single dam. And the average residue time at the strand near the shroud rises by 7.7%.
