Abstract
A new method for separation of non-metallic inclusions from a molten metal using traveling magnetic field is proposed. In this method, a bundle of thin tubes or a filter brick is used to suppress the mixing of inclusions due to the fluid motion caused by the non-uniformity of the electromagnetic force. The principle proposed here was confirmed by an experiment. A mathematical model was developed to evaluate the electromagnetic force acting on inclusions. A feasibility study on the application of the method to the separation of inclusions from a molten steel was performed. Figs 6, Refs 5.
