摘要： An electromagnetic device for pumping, circulating or transferring non-ferrous molten metal has a duct made of a refractory material with a first aperture at a first end of the duct and a second aperture at a second end of the duct. The duct conveys a body of non-ferrous molten metal between the first and second apertures. The duct encloses the body of non-ferrous molten metal between the first and second apertures. The duct has opposing first and second external side surfaces. A first inductor assembly extends adjacent to the first side surface. The first inductor assembly comprises a plurality of inductors arranged along a length of the duct adjacent to the first side surface. An electronic circuit generates direct current pulses that energise each inductor of the plurality of inductors in a sequence, so as to generate a moving magnetic field within the body of non-ferrous molten metal which propels the body of non-ferrous molten metal along the duct.

摘要： A metallurgical apparatus comprises a vessel for holding a body of liquid metal and a circulating apparatus for circulating the body of liquid metal within the vessel. The vessel has a peripheral wall and a base, and the circulating apparatus comprises a launder that provides an open-topped flow channel and a pumping device for pumping liquid metal through the launder. The launder has an inlet end connected to a first opening in the peripheral wall and an outlet end connected to a second opening in the peripheral wall. The pumping device is configured to pump liquid metal through the launder so that liquid metal flows out of the vessel through the first opening and into the vessel through the second opening, thereby causing the body of liquid metal within the vessel to circulate.
