A method of continuously casting metal in which the metal is subjected during its solidification at a predetermined zone to the action of a magnetic field which is controlled as a function of the withdrawal speed of the metal during the continuous casting thereof to maintain in the region of the solidification of the metal a magnetic pressure between two predetermined limits to thereby agitate the metal during its solidification to improve the structure of the cast product especially in a central axial zone of the product.

Method to improve the structure of cast metal during continuous casting

A jacketted mold for the continuous casting of molten metal is surrounded by a laterally confined space holding an electromagnetic inductor for moving the molten metal in the open-ended mold. Liquid cooling medium is supplied to the mold jacket through an inlet chamber at one end and is evacuated therefrom through an outlet chamber at the other end. The outlet chamber is in communication with the confined space so that the liquid cooling medium cools not only the mold but also the inductor.
