Kinetic analysis was made on the electromagnetic separation of nonmetallic inclusions from hollow cylindrical melt in an alternating electromagnetic field. Effects of various processing parameters such as magnetic flux density B e , imposing time t, particle diameter d p , the nondimensional parameters r 1 /δ and A on the removal efficiency η were analyzed theoretically. It is found that higher removal efficiency can be obtained in the hollow cylindrical melt than in the solid cylinder case under the same conditions. Generally, in order to obtain higher removal efficiency, the value of various parameters should be selected properly in hollow cylindrical melt case. For the inclusion particles with diameter larger than 5 μm, the removal efficiency can exceed 90 pct in the hollow cylindrical case with optimal processing parameters.
