A new method called mixed Lagrangian and Eulerian(MiLE)method was used to simulate the continuous casting process in a mold of free-cutting steel 38MnVS.The simulation results are basically in agreement with experimental data in the literature,achieving the three-dimensional visualization of temperature distribution,melt flow,shell thickness,and stress distribution of blooms in a mold.It is shown that the flow velocity of steel melt becomes smaller gradually as the casting proceeds.When the flow reaches a certain depth,two types of flow patterns can be observed in the upper zone of the mold.The first flow pattern is to flow downwards,and the second one is to flow upwards to the meniscus.The comer temperature is higher,and the thickness is thinner than those in the mid-face.The effective stress in the comer area is much bigger than that in the mid-face,indicating that the comer area is the dangerous zone of cracking.
