Mixing eductor nozzle and flow control device

A system comprising:

• a feed tube couplable to a source of molten metal;
• a primary nozzle located at a distal end of the feed tube, wherein the primary nozzle is submersible in a molten sump for delivering the molten metal to the molten sump;
• a secondary nozzle submersible in the molten sump and positionable adjacent the primary nozzle, wherein the secondary nozzle includes a restriction shaped to generate a low pressure area to circulate the molten sump in response to the molten metal from the source passing through the restriction
• a second primary nozzle located at the distal end of the feed tube, wherein the second primary nozzle is submersible in the molten sump for delivering the molten metal to the molten sump;
• a second secondary nozzle submersible in the molten sump and positionable adjacent the second primary nozzle, wherein the second secondary nozzle includes a second restriction shaped to generate a second low pressure area to circulate the molten sump in response to the molten metal from the source passing through the second restriction;
• and
• a flow control device adjacent the feed tube for controlling flow of the molten metal through the primary nozzle and the second primary nozzle, wherein the flow control device includes a plurality of permanent magnets positioned around the feed tube for generating a magnetic field through the feed tube and a plurality of electrodes electrically coupled to a pathway within the feed tube for conducting an electrical current through the molten metal within the feed tube.
