A new process for eliminating inclusions in a molten steel has been proposed. In the process, the electromagnetic vibration force induced by simultaneous imposition of a direct magnetic field and an alternating electric field is imposed on the molten metal to promote collision and coagulation of inclusions. In order to confirm the validity of the proposed process an experimental work was conducted by simulating silicon particles precipitated in an Al-Si alloy as the model of inclusions in a molten steel. It is found from the experiment that the optimum frequency of vibration exists and its reason is discussed from the theoretical viewpoint taking account of particle motion.
