Abstract

A system for removing molten metal from a vessel is disclosed. The system includes a pump and a refractory casing that houses the pump. As the pump operates it moves molten metal upward through an uptake section of the casing until it reaches an outlet wherein it exits the vessel. The outlet may be attached to a launder. Another system uses a wall to divide a cavity of the chamber into two portions. The wall has an opening and a pump pumps molten metal from a first portion into a second portion until the level in the second portion reaches an outlet and exits the vessel.

Claims

1. A device for use in transferring molten metal, the device comprising:

(a) a housing with one or more exterior walls, an outer surface, and an upper surface;

(b) a cavity defined within the housing;

(c) an opening in one of the one or more exterior walls, the opening in communication with the cavity and configured to be aligned with a pump outlet of a molten metal pump;

(d) one or more device brackets on the upper surface, at least one of the one or more device brackets including one or more extensions, the one or more extensions for lifting the device and placing it into or out of a vessel for retaining molten metal;

(e) an outlet; and

(f) a launder attached to the device, wherein the outlet is in fluid communication with the launder.

2. The device of claim 1 that further includes a mating structure for connecting to a molten metal pump and positioning the pump outlet next to the opening.

3. The device of claim 2, wherein the mating structure is configured to connect to a corresponding pump alignment structure on the molten metal pump.

4. The device of claim 1 that further includes a second device bracket for connecting to a launder.

5. The device of claim 4, wherein the second device bracket is connected to a corresponding bracket on the launder.

6. The device of claim 1, wherein the launder has a bottom surface with an opening therein.

7. The device of claim 1, wherein the outer surface has a rectangular cross section.

8. The device of claim 1 that includes a front side with one or more front flanges on the front side, and the launder has a first end proximal the device and a second end distal the device, the first end of the launder having one or more launder flanges, wherein each of the one or more launder flanges aligns with one of the one or more front flanges on the front side of the device for connecting the launder to the device.

9. The device of claim 1 that includes an inner bottom surface in the cavity.

10. The device of claim 1, wherein the launder has a top to retain heart.

11. The device of claim 1, wherein the launder rests on the top surface.

12. The device of claim 1, wherein the outlet is horizontal.

13. The device of claim 1, wherein the launder is horizontal.

14. The device of claim 1, wherein the cavity has a cross-sectional shape that is one of the group consisting of rectangular and cylindrical.

15. The device of claim 1 that further includes a molten metal pump positioned adjacent the outer surface such that the pump outlet is aligned with the opening.

16. The device of claim 1 that is connected to a launder and the outlet is in fluid communication with the launder.

17. The device of claim 8 that is connected to a launder, wherein the outlet is in fluid communication with the launder.

18. The device of claim 15, wherein the molten metal pump has a pump alignment structure and the device includes a first device bracket and the pump alignment structure is connected to the first device bracket.

19. The device of claim 1 that includes a first device bracket and a second device bracket and the launder is connected to the first device bracket and the second device bracket.

20. The device of claim 15, wherein the molten metal pump has one or more pump mounting arms configured to help position the molten metal pump adjacent the device such that the pump outlet is aligned with the opening.

21. The device of claim 18, wherein the pump alignment structure comprises a bar and the first device bracket comprises one or more holders, wherein the bar is received in the one or more holders.

22. A device for use in transferring molten metal, the device comprising:

(a) a housing with one or more exterior walls, an outer surface, and an upper surface;

(b) a cavity defined within the housing;

(c) an opening in one of the one or more exterior walls the opening in communication with the cavity and configured to be aligned with a pump outlet of a molten metal pump;

(d) one or more device brackets on the upper surface;

(e) a launder attached to the device, wherein the outlet is in fluid communication with the launder; and

(f) a front side with one or more front flanges on the front side, and the launder has a first end proximal the device and a second end distal the device, the first end of the launder having one or more launder flanges, wherein each of the one or more launder flanges aligns with one of the one or more front flanges on the device for connecting the launder to the device.

23. The device of claim 22 that further includes a mating structure for connecting to a molten metal pump and positioning the pump outlet next to the opening.

24. The device of claim 23, wherein the mating structure is configured to connect to a pump alignment structure on the molten metal pump.
