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.
