A system and method for transferring molten metal from a vessel and into one or more of a ladle, ingot mold, launder, feed die cast machine or other structure is disclosed. The system includes at least a vessel for containing molten metal, an overflow (or dividing) wall, and a device or structure, such as a molten metal pump, for generating a stream of molten metal. The dividing wall divides the vessel into a first chamber and a second chamber, wherein part of the second chamber has a height H2. The device for generating a stream of molten metal, which is preferably a molten metal pump, is preferably positioned in the first chamber. When the device operates, it generates a stream of molten metal from the first chamber and into the second chamber. When the level of molten metal in the second chamber exceeds H2, molten metal flows out of the vessel and into another structure, such as into one or more ladles and/or one or more launders.

A molten metal processing apparatus selected from a pump, a degasser, a flux injector, and a scrap submergence device constructed to include at least one element comprised of C/C composite.

An auxiliary heat exchanger that is used in conjunction with thermoplastic melter kettles. The auxiliary heat exchanger receives molten thermoplastic material from the bottom of a melter kettle, transports the molten thermoplastic material though the auxiliary heat exchanger and feeds the molten thermoplastic material into the top of the melter kettle thereby mixing hotter molten thermoplastic material from the bottom of the melter kettle into cooler thermoplastic material near the top of the melter kettle. The auxiliary heat exchanger includes an oil bath chamber and parallel heat transfer tubes that are arranged in a serpentine configuration and include motor drive augers to transport molten thermoplastic material through the auxiliary heat exchanger.
