Modeling of Continuous Electromagnetic Removal of Inclusions from Molten Metals

In this research, a 3-D mathematical model is developed for ...imutating electromagnetic continuous removal of inclusions from moUenmetilis. The model indude.ʹl the computation ofelectromagnetic force field andfluidfloitʹ in the presence of electromagnetic forces. The results of flow field together with etcctromugnetic force field were further usedfor calculating the trajectory ofinclusions in the molten metal, Parametric studies Hene performed to evaluate the effects of various parameters such Q.\ʹ magnetic field intensity, inclusion she, and fluid velocity on inclusion removal efficiency ill molten magnesium. In order to verify the mathematical model and visualize the trajectories ofparticles in the melt flow under electromagnetic force, a physical model was constructed. The predicted particle trajectories and separation in the pltY\ʹical model were compared with those obtainedfrom experiments. HI!ticll showed a relatively good agreement.
