Abstract

A method of galvanizing a workpiece. The method is performed using a trough. The trough includes connected walls configured to hold a molten galvanization material within the trough. The trough also includes a first end including a first gate system. The trough also includes a second end, opposing the first end, including a second gate system. The trough also includes a roller connected, inside the trough, to opposing inside walls of the connected walls. The trough also includes a sump disposed within the trough. The method also includes pumping the molten galvanization material into the sump until the molten galvanization material submerges the roller. The method also includes driving the workpiece through the first gate system, over the roller and through the molten galvanization material, and through the second gate system.

Claims (26)

1. A method of galvanizing a workpiece, wherein the method is performed using a trough, wherein the trough comprises: a plurality of connected walls configured to hold a molten galvanization material within the trough, wherein the trough further comprises: a first end comprising a first gate system; a second end, opposing the first end, comprising a second gate system; a roller connected, inside the trough, to opposing inside walls of the plurality of connected walls; a sump disposed within the trough; a plurality of side braces connected to an outside wall of the plurality of connected walls, the plurality of side braces extending outwardly from the outside wall; an inlet connected to the sump, the inlet disposed at a perpendicular angle relative to the outside wall and further disposed between the plurality of side braces; and a pump disposed between the plurality of side braces, wherein the pump is in fluid communication with the inlet;

the method of galvanizing the workpiece further comprising:

pumping, with the pump, the molten galvanization material through the inlet into the sump until the molten galvanization material submerges the roller; and

driving the workpiece through the first gate system, over the roller and through the molten galvanization material, and through the second gate system;

the method of galvanizing the workpiece further comprising, after driving the workpiece: removing a first gate from at least one of the first gate system and the second gate system; installing a second gate into the at least one of the first gate system and the second gate system, wherein the second gate is sized and dimensioned to hold a second workpiece having second dimensions different than first dimensions of the workpiece; and driving the second workpiece through the first gate system, over the roller and through the molten galvanization material, and through the second gate system, wherein the second gate is installed in the at least one of the first gate system and the second gate system;

wherein the removing of the first gate comprises:

removing a key that locks the first gate in place relative to the first end or relative to the second end; and removing the first gate from the first gate system or the second gate system.

2. The method of claim 1 , wherein the installing of the second gate further comprises: inserting the key to lock the second gate in place relative to the first end or relative to the second end.

3. The method of claim 1 , wherein the removing of the first gate and the installing of the second gate are performed while the molten galvanization material remains in the trough.

4. The method of claim 1 , wherein: the trough comprises a hook retainer extending outwardly from the first end and further comprises a slotted holder extending outwardly from the first end, and the first gate system comprises: the first gate comprising a guide pin and a top shelf, the guide pin disposed in the slotted holder; and the key is disposed between the top shelf and the hook retainer such that the key secures the first gate between the top shelf and the hook retainer.

5. The method of claim 4 , further comprising removing the first gate by: removing the key from the top shelf and the hook retainer; and removing, after removing the key, the first gate from the first gate system by removing the guide pin from the slotted holder.

6. The method of claim 5 , further comprising: installing, after removing the first gate, a second gate into the first gate system, wherein the second gate is sized and dimensioned to hold the second workpiece; inserting the key to lock the second gate in place by inserting the key between the top shelf and the hook retainer.

7. The method of claim 6 , further comprising:

driving, after inserting the key, the second workpiece through the first gate system, over the roller and through the molten galvanization material, and through the second gate system.

8. A method of galvanizing a workpiece, wherein the method is performed using a trough, wherein the trough comprises: a plurality of connected walls configured to hold a molten galvanization material within the trough, wherein the trough further comprises: a first end comprising a first gate system; a second end, opposing the first end, comprising a second gate system; a roller connected, inside the trough, to opposing inside walls of the plurality of connected walls; and a sump disposed within the trough;

the method further comprising: pumping the molten galvanization material into the sump until the molten galvanization material submerges the roller; and driving the workpiece through the first gate system, over the roller and through the molten galvanization material, and through the second gate system;

further comprising, after the driving of the workpiece: removing a first gate from at least one of the first gate system and the second gate system; installing a second gate into the at least one of the first gate system and the second gate system, wherein the second gate is sized and dimensioned to hold a second workpiece having second dimensions different than first dimensions of the workpiece; and driving the second workpiece through the first gate system, over the roller and through the molten galvanization material, and through the second gate system, while the second gate is installed in the at least one of the first gate system and the second gate system.

9. The method of claim 8 , wherein removing the first gate and installing the second gate are performed while the molten galvanization material remains in the trough.

10. A method of galvanizing a workpiece, wherein the method is performed using a trough, wherein the trough comprises: a plurality of connected walls configured to hold a molten galvanization material within the trough, wherein the trough further comprises: a first end comprising a first gate system; a second end, opposing the first end, comprising a second gate system; a roller connected, inside the trough, to opposing inside walls of the plurality of connected walls; and a sump disposed within the trough;

the method further comprising: pumping the molten galvanization material into the sump until the molten galvanization material submerges the roller; and driving the workpiece through the first gate system, over the roller and through the molten galvanization material, and through the second gate system;

wherein: the trough comprises a hook retainer extending outwardly from the first end and further comprises a slotted holder extending outwardly from the first end, and the first gate system comprises: a first gate comprising a guide pin and a top shelf, the guide pin disposed in the slotted holder; and a key disposed between the top shelf and the hook retainer such that the key secures the first gate between the top shelf and the hook retainer.

11. The method of claim 10 , further comprising removing the first gate by: removing the key from the top shelf and the hook retainer; and

removing, after removing the key, the first gate from the first gate system by removing the guide pin from the slotted holder.

12. The method of claim 11 , further comprising: installing, after removing the first gate, a second gate into the first gate system, wherein the second gate is sized and dimensioned to hold a second workpiece having second dimensions different than first dimensions of the workpiece; inserting the key to lock the second gate in place by inserting the key between the top shelf and the hook retainer.

13. The method of claim 12 , further comprising:

driving, after inserting the key, the second workpiece through the first gate system, over the roller and through the molten galvanization material, and through the second gate system.
