AbstractA macrosegregation model, based on the continuum formulation, is developed to evaluate momentum, heat and mass transfers during electromagnetic centrifugal solidification. Using a non-inertial coordinate system, the model is applied to predict Al-5%Cu alloy solidification under electromagnetic centrifugal solidification. The results show that the effect of electromagnetic force on melt lowers the radial component velocity of melt flow. The change of melt flow decreases the inverse segregation at outer position of the solidifying alloy and the negative segregation at the mushy zone. Electromagnetic centrifugal solidification lessens marcogregation compared with conventional centrifugal casting. Good agreement is found between the simulation and experiment results, which shows the electromagnetic centrifugal solidification can be described well by this model.
