Abstract:A three dimensional model for simulating the semi-continuous solidification process accompanying mass-transfer in electromagnetic casting (EMC) of aluminum alloys was described in this paper. The electromagnetic skin-effect and the Joule heating were incorporated into the computation equation by a proposed formula. Numerical and experimental results describing the solidification process of an aluminum ingot cast on a pilot-scale caster were presented in order to show the efficiency of the model. And the effects of casting speed and pouring temperature on the solidification front were also analyzed.
