Abstract
A system for treating wire includes an elongated vessel that contains a molten fluid. A pump is disposed in the molten fluid in the vessel. The pump includes an elongated discharge conduit extending for at least a portion of the length of the vessel. Conveyance structure enables the wire to be conveyed through the molten fluid. Operation of the pump enables a temperature of the molten fluid in the vessel to be changed. The wire is heat treated as a result of passing through the molten fluid.
Claims34
The system for treating wire of claim 12 wherein said pump include a motor, a pump shaft driven by said motor, a base including an impeller chamber, an impeller connected to said pump shaft and rotatably disposed in said impeller chamber, said base including at least one inlet and at least one said pump outlet, said elongated discharge conduit in fluid communication with said impeller chamber.

A system for treating wire, comprising:
- an elongated vessel that contains a molten fluid;
- a pump disposed in the molten fluid in said vessel, wherein said pump includes an elongated conduit extending for at least a portion of the length of said vessel said elongated conduit including an inlet at a location of cooler molten fluid in said vessel, wherein a hot spot is near a wire entry location of wire into the molten fluid contained in said vessel, the cooler molten fluid being remote from said wire entry location, a pump outlet being positioned so as to discharge the cooler molten fluid into the hot spot of the molten fluid;
- and
- conveyance structure that enables the wire to be conveyed through the molten fluid;
- wherein operation of said pump enables the hot spot to be cooled by the cooler molten fluid in said vessel and the wire is heat treated as a result of passing through the molten fluid.
A method for treating metal wire comprising:
- conveying the wire through molten fluid contained in a vessel;
- moving the molten fluid in said vessel using a pump submerged in the molten fluid, said pump including an elongated conduit in said vessel, wherein the molten fluid includes a hot spot;
- moving cooler molten fluid in said vessel with said pump to the hot spot of the molten fluid so as to cool the hot spot;
- and
- heat treating said wire as a result of moving through the molten fluid.

A system for treating wire, comprising:
- an elongated vessel that contains a molten fluid;
- a pump disposed in the molten fluid in said vessel, wherein said pump includes an elongated conduit extending for at least a portion of the length of said vessel, said elongated conduit extending between a location of cooler molten fluid in said vessel and a location near an entry location of hot wire in the molten fluid of said vessel;
- conveyance structure that enables the wire to be conveyed through the molten fluid, wherein the wire is heat treated as a result of passing through the molten fluid;
- and
- a temperature sensor in the molten fluid and a controller connected to said temperature sensor, wherein a temperature is programmed into said controller and said controller is adapted to activate the pump to pump the molten fluid when the temperature sensor senses a different temperature so as to change the temperature of the molten fluid.
