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 pumping device for pumping molten metal, the device including (a) a pump having a motor, a rotor and a drive shaft connecting the motor to the rotor, and (b) a portable refractory casing that includes an inlet, an uptake tube having a first section with a first cross-sectional area and a second section with a second cross-sectional area, therein the second section is above the first section and the second cross-sectional area is larger than the first cross-sectional area, and an outlet in communication with the second section (c) the rotor being received in the first section, and (d) the pump being removable from the casing without removing the casing from a molten metal bath.

2. The pumping device of claim 1 that further includes a launder attached to the outlet.

3. The pumping device of claim 1 wherein the casing has a rectangular outer surface.

4. The pumping device of claim 1 wherein the pump rests on a platform above the casing.

5. A device for moving molten metal out of a vessel, the device inside of a vessel in fluid communication with and physically separated from a reverbatory furnace, the device including:

(a) a dividing wall oriented perpendicular to a wall of the reverbatory furnace, the dividing wall having an opening;

(b) a first chamber on a first side of the dividing wall, the first chamber including a pump for pumping molten metal;

(c) a second chamber, a second side of the dividing wall;

(d) an exit in fluid communication with the second chamber, the exit being formed in a front wall of the vessel; and

(e) the dividing wall having a height and the exit having a height, the height of the exit being lower than the height of the dividing wall.
