The numerical simulation of molten steel flow field in a 40 t tundish for alloy steel billet concasting at Shijiazhuang lron and Steel has been carried out using Computational Fluid Dynanics (CFD) software PHOENICS to modify the one weir structure which influence molten steel flowing to improved one weir and one dam structure. The results of application showed that after using improved structure the average T[O
