Method of transferring molten metal from a vessel
First Claim
1. A method of moving molten metal out of a vessel that includes a bottom surface, a cavity, a transfer chamber formed in the cavity and an opening beneath the transfer chamber, the transfer chamber comprising:
- an uptake section with a restricted area, the restricted area configured to receive at least part of a rotor, and an outlet above the restricted area and above the opening, the outlet in communication with the uptake section and leading out of the vessel;
wherein the bottom surface of the vessel extends below the uptake section and the outlet, the method comprising the steps of;
(a) causing molten metal to flow towards the opening in the vessel; and
(b) pumping molten metal from the opening, up the uptake section, and out of the outlet where the molten metal exits the vessel.

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.
