Abstract
An apparatus is provided for electromagnetically coiling a molten material into a longitudinally extending casting defining a longitudinal axis thereof. The casting has a desired cross section extending perpendicular to the longitudinal axis. At least one portion of the outer peripheral surface of the casting extends transversely of the longitudinal axis and has a small radius of curvature. The apparatus includes an inductor extending transversely about the molten material for providing an electromagnetic containment force field acting on the outer peripheral surface of the molten material to form the desired cross section. The improvement comprises a device for turning the electromagnetic containment force field about the longitudinal axis to cause a corresponding turn of the transverse cross section of the molten material about the longitudinal axis.
