Separation of Inclusions in Liquid Metal Using Fixed Alternating Magnetic Field

Abstract

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 ≡(ρfdp2Be2LtS) (μfμeWdt2) which characterizes an electromagnetic inclusion separation process is newly proposed.
