Benefits of technology
The patent describes a system and method for heat treating wire using a molten fluid. The system includes an elongated vessel with a pump and a discharge conduit for conveying the wire through the molten fluid. The pump can be positioned near the edge of the trough to facilitate the wire's passage without interfering with the pump. The system can maintain a uniform temperature throughout the bath by circulating the molten fluid. The use of the pump avoids the need for energy-intensive fans and can control the temperature, viscosity, and density of the molten fluid. The system is energy-efficient and can be adapted for different production needs.
Problems solved by technology
This method can be inefficient for a number of reasons.
Aiming the fan nozzles at specific hot spots is difficult.
Depending on the size of the bath, a large number of fans may be required which causes a great deal of power to be used to cool the bath.

Embodiment Construction
[0025]This disclosure features a system 10 for heat treating metal wire 12. A vessel 114 is filled with molten fluid 16 to create a bath for treating the wire 12. A pump 18 for pumping the molten fluid 16 is placed in the vessel 114. A motor mount 20 is disposed above the molten fluid 16 contained in the vessel 114. A motor 22 is supported by the motor mount 20. Submerged in the molten fluid 16 is a base 24 that includes an impeller chamber 26. A molten fluid inlet opening 28 is disposed in the impeller chamber 26 and a molten metal outlet in the form of a discharge passageway 32 extends from the impeller chamber 26 to outlet orifice 30 at an exterior surface of the base 24. The base 24 is submerged in the molten fluid 16. The base 24 is connected to the motor mount 20 by support posts 34 that are attached to the base 24 and attached to the motor mount 20 as known in the art. A pump shaft 36 is connected to a drive shaft 38 of the motor 22 at one end via a coupling 40 as known in th...

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.
Description
TECHNICAL FIELD[0001]This pertains to the field of systems for treating wire in molten fluids, particularly molten lead.BACKGROUND[0002]In the course of heat treating wire it is sometimes beneficial to treat the wire in a molten fluid bath. When a molten lead bath is employed for annealing steel wire, elaborate heat control means are employed to maintain a proper lead temperature throughout the length of the bath. The lead bath is contained in an elongated trough. The wire that enters the bath is very hot and the bath quickly heats up as a result of the wire passing through it. One known method of attempting to maintain the lead bath temperature is directing fans at the warmer sections of the bath in an effort to cool them. This method can be inefficient for a number of reasons. Aiming the fan nozzles at specific hot spots is difficult. Even if the nozzles are directed at a specific hot spot, the spot may shift. Depending on the size of the bath, a large number of fans may be requir...
