Transferring molten metal from one structure to another
First Claim
1. A system for transferring molten metal from a vessel, the vessel comprising molten metal having a surface, at least a first chamber and a second chamber, each of which includes molten metal therein, the first chamber and second chamber being separated by a dividing wall including an opening beneath the surface, the system further comprising:
- a pump having a pump base fully submerged in the molten metal during operation, the pump base having a pump chamber and a top opening through which molten metal enters the pump chamber during operation, and an outlet through which molten metal exits the pump base;
the pump configured to fit into the first chamber such that at least some molten metal exiting the outlet moves through the opening in the dividing wall and into the second chamber in order to raise the level of molten metal in the second chamber to a level at which molten metal flows out of the second chamber; and
a degasser in one or both of the first chamber and second chamber, wherein the degasser is operated to degas the molten metal.

Abstract
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.
