Electromagnetic augmentation for casting of thin metal sheets
This patent describes an apparatus for the horizontal casting of thin metal sheets. The apparatus consists of: vessel means containing a molten metal and including an aperture for discharging the molten metal in the form of a thin horizontal sheet; mold means for receiving, confining and directing the molten metal sheet and for removing heat from the molten metal sheet in effecting the solidification thereof; electromagnetic conducting means including a DC conductor disposed about the metal sheet for directing a DC magnetic field along the direction of displacement of and about the metal sheet; and a DC voltage source coupled to the metal sheet for establishing a direct current therein, such that the direct current interacts with the DC magnetic field for generating and exerting a constant uniform levitation force on the metal sheet wherein the pressure exerted by the metal sheet upon the mold means is reduced to zero.
