The oxygen content of the product of this kind of process is low, which can reach about 500ppm, but this kind of process needs to go through the process of electric heating steam boiler, which will increase the production cost and is not conducive to cost control
And it is necessary to provide equipment for electric heating steam boiler, and the cost is further increased

Embodiment Construction
[0015] The present invention will be further described below in conjunction with accompanying drawing.
[0016] In the figure: incoming wire 1, wire drawing 2, annealing 3, reduced copper soft wire 4, wire take-up 5, finished product inspection 6.
[0017] as attached figure 1 Shown, the technique that reduction coolant of the present invention reduces copper wire is to be finished by following steps:
[0018] (1) For incoming wires, the raw material oxygen-free round copper wires are first screened according to product specifications.
[0019] (2) Wire drawing, put the screened oxygen-free round copper wire into a wire drawing machine of corresponding specifications for wire drawing, and draw the oxygen-free round copper wire into a round copper flexible wire of a standard size.
[0020] (3) Annealing, the round copper soft wire is passed into an annealing machine for heating and annealing.
[0021] (4) Reduction copper soft wire, the annealed hot copper soft wire directl...

The invention provides a process for reducing a copper lead wire through a reduction coolant and belongs to the field of treating an electric wire. The process for reducing the copper lead wire through the reduction coolant is completed by the following steps: (1) coiling in and winding up: screening raw materials of oxygen-free round copper wires according to a product specification; (2) drawing: placing the screened oxygen-free round copper wires into a wire drawing machine with corresponding specification, and drawing the oxygen-free round copper wires to obtain round copper flexible wires with a standard size; (3) annealing: feeding the round copper flexible wires into an annealing machine for heating and annealing; (4) reducing the copper flexible wires, directly feeding the annealed thermal copper flexible wires into a reduction coolant feeding tank, controlling a dosage by a reduction coolant controller, carrying out reduction reaction on the thermal copper flexible wires, removing copper oxide, and cooling the thermal copper flexible wires to a temperature approximating to a room temperature, so that a temperature of the copper flexible wires is lower than a temperature requested by a condition that copper and oxygen react, and no copper oxide generates; (5) winding up: recycling and winding the reduced and cooled copper flexible wires in a bundle by a winding-up machine; and (6) inspecting a finished product: inspecting the quality of a product. The process provided by the invention can be used for effectively treating the copper oxide, and has the advantages of simple structure, no side effect and reduction of energy consumption.
Description
technical field [0001] The process for reducing copper conductors by reducing coolants in the invention belongs to the technical field of electric wire and cable manufacturing. Background technique [0002] In recent years, with the development of science and technology, people have higher and higher requirements for products. The requirements for copper conductors are also getting higher and higher. The general copper soft wire production process mainly consists of the following steps: drawing copper wire through a 17-die mid-drawing machine, annealing through an annealing furnace, pumping out air through a vacuum pump during annealing, and then filling it with protective gas for protection and cooling. Although the copper soft wire produced by this process can be used, the oxygen content of the product is high, reaching more than 3000ppm, and the color of the product is black. This process technology is backward and the quality is unstable. Another process is through the...
