Transferring molten metal from one structure to another
First Claim
1. A method of utilizing a molten metal pump for transferring molten metal from a first vessel, the first vessel comprising at least a first chamber and a second chamber, the first chamber and second chamber being separated by a dividing wall having a height H1 and the molten metal pump being positioned in the first chamber and having a pump base that is fully submerged in the molten metal, the method comprising:
- the pump pumping molten metal from the first chamber through an opening in the dividing wall and into the second chamber to raise the level of molten metal in the second chamber until it flows out of an outlet juxtaposed the top of, or at the top of, the second chamber and into a second vessel, wherein the outlet has a height H2 that is less than height H1.

Abstract
A system 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.
