Abstract
The invention relates to a conduction pump for liquid metal. This pump comprises a magnetic circuit for creating a magnetic field in the stream of liquid metal circulating in a pipe, and a turn, filled with liquid metal, for supplying an electric current perpendicular to the magnetic field in the stream of liquid metal. The turn is arranged at the level of the gap zone of the magnetic circuit, perpendicular to the field in this gap, and at least partially surrounds the magnetic circuit so that the electric current is generated in the turn by the circuit. The turn is at least partially formed by the circulation pipe itself. The invention is applied in particular to the conveying of liquid aluminium by pumping.
Claims4
A conduction pump for liquid metal comprising:
- a part of refractory material immersed in liquid metal defining a circulating pipe for said metal, in which one part is defined by a channel of flat shape where the metal circulates from bottom to top, said circulating pipe forming a vertical coil for liquid metal comprising a member in communication with the liquid metal circulating in said channel;
- a single magnetic circuit, having an air gap in the interior of which said channel passes and being surrounded at least partially by the coil, at the level of the air gap;
- at least another coil fed by alternating current creating a magnetic field in a horizontal direction in the air gap and causing circulation in said coil, of an induced current which circulates at the level of said channel in a horizontal direction perpendicular to the magnetic field and a vertical force which is directed toward the top, being produced by the joint action of said field and current, on the metal in said channel.
