  • Apparatus and method for magnetically confining molten metal
    Patent number: 5197534
    Abstract: Molten metal, in the gap between two counter-rotating rolls of a continuous strip-casting apparatus, is prevented from leaking out of an open side of the gap by a magnetic confining apparatus employing the proximity effect to produce a horizontal magnetic field extending through the open side of the gap. The apparatus includes structure for confining the magnetic field substantially to the open side of the gap and for preventing dissipation of the magnetic field away from the open side of the gap.

  • Electromagnetic metering of molten metal
    Patent number: 5137045
    Abstract: A descending stream of molten metal is electromagnetically metered by a primary coil surrounding an upstream portion of the stream. Alternating electric current flows through the coil, and the frequency of that current is controlled to optimize the electromagnetic efficiency (magnetic pressure/power loss) of the electromagnetic metering system. Direct current can be added to the alternating current to also optimize electromagnetic efficiency.
