Abstract
An apparatus and process electromagnetically forms feed ribbon or rod material into a desired thin strip shape. Inductors contain and form the material in molten form into the desired shape. There are at least an upstream and downstream inductor for applying the magnetic field to the molten material. Both the upstream and downstream inductors may be jointly used to contain and form the molten material into the thin strip shape. An alternating current is applied to the inductors to generate the magnetic field. This magnetic field defines a containment zone for the molten material and a gap between the molten material and the inductors. The current is applied to the inductors so that the gap remains substantially constant. The feed material has an upstream and a downstream liquid-solid interface adjacent the upstream and downstream inductors, respectively, which define the molten material head and solid material portions of the material. The feed material is delivered to the containment zone at a desired delivery rate while the desired thin strip is withdrawn from the containment zone at a desired withdrawal rate. The location of each of the liquid-solid interfaces is monitored and their positions are controlled so that the desired thin strip shape is of uniform size and shape.
