Abstract
An apparatus or process for casting metals by electromagnetically forming molten metal into a desired shape by applying a magnetic field to the molten metal. The magnetic field defines a containment zone for the molten metal. The hydrostatic pressure exerted by the molten metal in the containment zone is sensed and in response thereto the flow of molten metal into the containment zone is controlled. This minimizes changes in the hydrostatic pressure.
