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.

Claims

1. A vessel for use in a system for transferring molten metal, the vessel including a cavity, a transfer section having:

a transfer chamber with an opening in communication with the cavity, the transfer chamber having an uptake section above the opening, and an outlet above the opening, the outlet in communication with the uptake section.

2. The vessel of claim 1 that also includes an inner bottom surface that slopes downward towards the opening.

3. The vessel of claim 1 that further includes a tap-out opening positioned lower than the opening.

4. The vessel of claim 1 wherein the outlet is at least two feet above the opening.

5. The vessel of claim 2 wherein the outlet is at least two feet above the inner bottom surface.

6. The vessel of claim 1 that is comprised of refractory material.

7. The vessel of claim 1 wherein the opening has a cross-sectional area and the transfer chamber has a second cross-sectional area, the second cross-sectional area being larger than the cross-sectional area.

8. The vessel of claim 7 wherein the transfer chamber is cylindrical.

9. The vessel of claim 1 wherein the transfer chamber has a first section with a first cross-sectional area and a second section having a second cross-sectional area, the second cross-sectional area adjacent the opening, and the second cross-sectional area being larger than the first cross-sectional area.

10. The vessel of claim 1 wherein the opening has a cross-sectional area and the transfer chamber has a second cross-sectional area, the second cross-sectional area being smaller than the cross-sectional area.

11. The vessel of claim 9 wherein the transfer chamber further includes a third section having a third cross-sectional area, the third section being between the first section and the second section, and the third cross-sectional area being smaller than the first cross-sectional area, but larger than the second cross-sectional area.

12. The vessel of claim 1 that has a first side wall and a second side wall opposite the first side wall, and that comprises one or more brackets for supporting the pump above the vessel, and the one or more brackets comprises two metal beams that extend from the first side wall to the second side wall, and each bracket is connected to the first side wall and the second side wall.

13. The vessel of claim 12 wherein each bracket is flat.

14. The vessel of claim 12 wherein each bracket is L-shaped.

15. The vessel of claim 1 wherein the outlet is two feet or more above the opening.

16. The vessel of claim 1 that further includes a wall dividing the vessel into a first section, and a second section that includes the transfer section.

17. The vessel of claim 1 that further includes a launder in communication with the outlet so that fluid exiting the outlet passes into the launder.

18. The vessel of claim 2 wherein the opening is 3″

or more above the inner-bottom surface.

19. The vessel of claim 1 that has walls, and the transfer section has three walls inside the vessel and shares a fourth, common wall with the vessel.
