TRANSFERRING MOLTEN METAL FROM ONE STRUCTURE TO ANOTHER
First Claim
1. A method for transferring molten metal from a vessel, the vessel comprising at least a first chamber and a second chamber, the first chamber and second chamber being separated by a dividing wall, the method comprising:
- pumping molten metal from the first chamber through the dividing wall into the second chamber to raise the level of molten metal in the second chamber until it flows out of the second chamber.

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.
