Provided are an agitation device, a melting apparatus, and a melting method which achieve good melting efficiency without contaminating molten metal. The agitation device (150) is provided with a traveling magnetic field generating unit (160) which is disposed outside a charging tank (20) for storing molten metal (3) and generates, inside the charging tank (20), a magnetic field that travels downward along the rear sidewall (22) of the charging tank (20), whereby a flow of the molten metal (3) that rotates longitudinally about an axis approximately parallel to the surface of the molten metal (3) is produced in the molten metal (3). By charging aluminum cutting chips (2) into the molten metal (3) in which the flow is produced, the aluminum cutting chips (2) move with the flow of the molten metal (3), get into the molten metal (3) roughly in the position where a downward flow of the molten metal (3) is produced, and are immersed in the molten metal (3), and thus the melting of the aluminum cutting chips (2) is accelerated. |
