Method and apparatus for the vertical casting of metal melts

摘要

Molten metal passing through an outlet opening is guided in free fall by a magnetic field which rotates about the vertical axis of the opening to impress a rotation in the stream of molten metal. A further magnetic field rotating at the same rate but out of phase with the first can increase the rotation. At least one toroidal magnetic field coaxial with the rotating field can be used to shape the cross section of the pouring stream.
