1. A method for transferring molten metal from a first vessel configured to contain molten metal, wherein the first vessel comprises:
- (a) interior walls;
(b) a cavity defined by the interior walls, the cavity configured for retaining molten metal;
(c) an opening in communication with the cavity;
(d) an uptake section that is above, and in fluid communication with, the opening, wherein the uptake section is configured to move molten metal upward and therethrough, (e) an outlet above the opening, the outlet in fluid communication with the uptake section, wherein the outlet is configured so that molten metal can exit the uptake section through the outlet;
(f) a molten metal pump having a motor, a drive shaft having a first end connected to the motor and extending into the uptake section, the drive shaft further having a second end connected to a rotor, wherein the rotor is configured to move molten metal upward into the uptake section; and
(g) a tap-out opening positioned lower than the opening;
the method comprising the steps of;
operating the pump to move molten metal in the first vessel up into the uptake section and through the outlet.

Abstract
The invention relates to systems for transferring molten metal from one structure to another. Aspects of the invention include a transfer chamber constructed inside of or next to a vessel used to retain molten metal. The transfer chamber is in fluid communication with the vessel so molten metal from the vessel can enter the transfer chamber. A powered device, which may be inside of the transfer chamber, moves molten metal upward and out of the transfer chamber and preferably into a structure outside of the vessel, such as another vessel or a launder.
