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.
Claims20
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.
