Abstract
A multi-strand apparatus and process for casting molten material into ingots of desired shape. A plurality of structures are provided for receiving and electromagnetically forming the molten material into the desired shape. Each receiving and forming structure includes an inductor for applying a magnetic force field to the molten material. When the inductor is in operation, it is spaced from the molten material by a gap extending from the surface of the molten material to the opposing surface of the inductor. Structure is provided for distributing a current in the inductor to generate the magnetic field. The improvement comprises a device arranged below the inductor for modifying the current distribution in the inductor to minimize the variations in the gap.
