PURPOSE: To change the sectional dimension of metallic ingots continuously with simple installations by holding the side faces of the molten metal right after casting by means of an electromagnetic force and changing and adjusting the intensity of the electromagnetic holding force and casting speed.
CONSTITUTION: When AC current J is applied to an induction coil 4, the current J' in the direction opposite from that of the coil 4 flows in the surface of molten metal 3 opposed to the coil 4 by the effect of the AC magnetic field H generated by said current, then an electromagnetic force F acts. The force F is the force in the direction where the metal 3 does not contact with a non-metallic mold 2 and one side of the molten metal is held by the electromagnetic force. If such electromagnetic holding force is controlled by changing and adjusting said force in association with the casting speed, the shape of the molten metal changes and the sectional dimension such as width or thickness of the ingot is changed.
