Abstract

A system for removing molten metal from a vessel is disclosed. The system includes a vessel having a first section and a second section and a pump positioned in the first section of the vessel. As the pump operates it moves molten metal through a pump discharge and through an opening into the second section of the vessel, where the molten metal reaches a vessel outlet and exits the vessel. The pump discharge is preferably formed at an angle to the vessel outlet. The outlet may be attached to a launder.

Claims

1. A system for moving molten metal out of a vessel having a first section and a second section, the system comprising:

(a) a pump positioned in the first section of the vessel, the pump having a motor, a drive shaft having a first end connected to the motor and a second end connected to a rotor, and a pump discharge;

(b) a dividing wall between the first section and the second section, and an opening in the dividing wall, the pump discharge being aligned with the opening; and

(c) a vessel outlet in the second section, the vessel outlet positioned above the pump discharge and above the opening in the dividing wall, the vessel outlet being at an angle of 90 degrees relative the pump discharge.

2. The system of claim 1 that further includes a launder in fluid communication with the vessel outlet.

3. The system of claim 2 wherein the launder has a bottom surface and the outlet has a bottom surface that aligns with the launder bottom surface.

4. The system of claim 1, wherein the pump further includes a superstructure that supports the motor, wherein the super structure is a steel platform.

5. The system of claim 2 wherein the vessel 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.

6. The system of claim 4, wherein the superstructure comprises a bracket configured to attach to a mounting flange, wherein the mounting flange is attached to the vessel, such that when the bracket is connected to the mounting flange, the pump discharge aligns with the opening.

7. The system of claim 1 wherein the pump is a circulation pump.

8. The system of claim 1 wherein the pump is a gas-release pump.

9. The system of claim 1 wherein the vessel has a bottom surface and the opening is above the bottom surface.

10. The system of claim 2 wherein the launder has a top to retain heat.

11. The system of claim 1 wherein the second section has a top to retain heat.

12. The system of claim 2 wherein the launder has a top to retain heat and the second section has a top to retain heat.

13. The system of claim 2 wherein the vessel has a top surface and the launder is supported by the top surface.

14. The system of claim 1 wherein the outlet is straight.

15. The system of claim 1, wherein the vessel comprises refractory material.

16. The system of claim 1 wherein the rotor is two-staged, having a first portion that drives molten metal into the pump chamber, and a second portion that pushes molten metal outward against the pump chamber wall and out of the pump discharge.

17. The system of claim 5, wherein the pump further includes a second side and a second mounting flange on the second side of the super structure, the second mounting flange configured to connecting to and position the pump in the vessel.

18. The system of claim 1, wherein the outlet is formed in a top surface of the vessel.
