The principle on separating inclusions in a molten metal by using a fixed alternating magnetic field has been confirmed through experiments with molten aluminium. The separating efficiency of inclusions is studied through experimental and analytical ways under different operating conditions. The mathematical model to predict the separating efficiency is developed and the efficiencies predicted by the model are compared with the experimental ones.
A feasibility study on the application of an electromagnetic inclusion separation in a molten steel is performed. An operating non-dimensional parameter, Y ≡(ρ_fd_p²B_e²L_tS) (μ_fμ_eWd_t²) which characterizes an electromagnetic inclusion separation process is newly proposed.
