Abstract
A casting furnace for continuous casting of magnesium comprises a furnace body divided into at least two compartments by at least one vertical weir. Inside each compartment, an upper layer of molten magnesium is in contact with a lower layer of a liquid heating medium, preferably a molten salt. The top of the weir is situated below a maximum level of the molten magnesium in the furnace. The weir is free of openings between its top and the magnesium/salt interface. The molten magnesium from primary (electrolytic) production or an alloy preparation furnace is introduced into a feed compartment of the furnace through a discharge pipe having means to direct the magnesium horizontally along the magnesium/salt interface, thereby minimizing intermixing of the magnesium and salt layer. The weir(s) separating the compartments minimize the effects of turbulence on the magnesium being pumped from the extraction compartment and also assist in minimizing the intermixing of the magnesium and salt layers, thereby providing a more energy efficient casting process capable of producing high quality castings.
