摘要	A fully coupled fluid flow, heat and solute transport model is developed to predict velocity of melt flow during electromagnetic centrifugal casting. As a result, melt flow can be yielded in the opposite direction of rotating mold owing to an electromagnetic force. The velocity of melt flow displays periodicity and reaches the maximum at the solidifying front. The stronger the magnetic flux densities, the larger the maximum of melt flows. Based on FEM software ANSYS, the dendrites stress states are computed using the results of the melt flow as computing parameters. It is found that the melt flow is largely changed when melt flows around the dendrite, the dendrites can be fractured by the melt flow. So the electromagnetic stirring contributes to the columnar-to-equiaxed transition because of increasing the number of fractured dendrites.
