Title:
DEVICE FOR PUMPING MOLTEN METAL
Document Type and Number:
WIPO Patent Application WO/1990/004878
Kind Code:
A1
Abstract:
A device for pumping molten metal comprises a centrifugal conduction-type magneto-hydrodynamic pump (1) placed in the vessel with the molten metal and comprising a metal casing (3) with a cap (4) to whose internal surface is connected, by one of its ends, a metal rod (6) embraced by a solenoid (7), whereas between the other end of the metal rod (6) and the bottom (5) of the metal casing is mounted axially to the rod (6) an electrically insulated chamber (8). The metal casing (3) together with the cap (4) and the bottom (5), as well as the rod (6), the solenoid (7) and a working chamber (8) form, together, a closed magnetic system as a result of which a magnetic field is generated in the cavity of the working chamber (8) having a maximum possible value of magnetic induction for a given value of the direct current passing through the solenoid (7). The working chamber (8) is connected to the vessel (2) with the molten metal and is hermetically connected to a sleeve for discharging the molten metal.
