Abstract
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
The present invention reduce cooling agent reduction copper conductor technique belong to technical field of wire cable manufacture.
Background technology
In recent years, along with the development of science and technology, the requirement of people to product is more and more higher.Requirement for copper conductor is also more and more higher.General copper flexible cord production technology forms primarily of following step: by wire drawing machine in 17 moulds to copper cash wire drawing, by anneal, deflated during annealing by vacuum pump, is then filled with protective gas and carries out protection cooling.Although this kind of explained hereafter copper flexible cord out can use, the oxygen content of its product is higher, reaches more than 3000ppm, and product color is partially black, and this kind of technology falls behind, and quality is unstable.Another kind of technique is by wire drawing contact annealing machine, carries out steam protection, add water cooling during annealing by electric heating steam boiler.The product oxygen content of this kind of technique is lower, can reach about 500ppm, but this kind of technique needs the operation through electric heating steam boiler, and this operation can improve production cost, is unfavorable for the control of cost.And equipment electric heating steam boiler must be provided, cost improves further.
Summary of the invention
The object of the invention is to avoid the deficiencies in the prior art part, and provide one effectively can remove cupric oxide content in copper flexible cord, reduce the technique of the reduction cooling agent reduction copper conductor of production cost.
The object of the invention is to be reached by following measures, the technique of reduction cooling agent reduction copper conductor is completed by following steps:
(1), inlet wire; First corresponding anaerobic circular copper wire to be selected according to the specification of product and purposes,
(2), wire drawing; Choose corresponding wire drawing die and wire drawing carried out to circular copper wire, pull into the round copper rigid line meeting product specification,
(3), anneal; Round copper rigid line after wire drawing is annealed by being put into annealing machine,
(4) native copper flexible cord, is gone back; Reduce at the round copper flexible cord that high temperature is oxidized to during annealing, add reducing agent and reduce,
(5), take-up; With admission machine to the round copper flexible cord inlet wire take-up after reduction,
(6), product inspection; To the quality inspection of finished product inlet wire.
Reduction cooling agent reduction copper conductor of the present invention plays copper flexible cord and reduces cupric oxide content, strengthens the effect of gloss.Direct being passed through by the copper flexible cord of high temperature, in reduction cooling agent service tank, supplies by reduction cooling agent the dosage that controller controls interpolation reduction cooling agent after anneal, to the reduction of copper flexible cord inlet wire, and elimination cupric oxide.
Reduction cooling agent of the present invention is made up of glycerin solution or isopropanol water solution, and the ratio of glycerol or isopropyl alcohol and water is 1:1.5, is reduced to the cupric oxide in copper flexible cord by the reproducibility of glycerol or isopropyl alcohol.
The present invention effectively can process cupric oxide, and structure is simple, has no side effect, and reduces energy consumption.
Accompanying drawing explanation
Accompanying drawing 1 is process flow diagram of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
In figure: inlet wire 1, wire drawing 2, annealing 3, goes back native copper flexible cord 4, take-up 5, product inspection 6.
As shown in Figure 1, the technique of reduction cooling agent reduction copper conductor of the present invention is completed by following steps:
(1), inlet wire, first according to product specification screening raw material anaerobic circular copper wire.
(2), wire drawing, the wire drawing machine that the later anaerobic circular copper wire of screening puts into corresponding specification is carried out wire drawing process, anaerobic circular copper wire is pulled into the round copper flexible cord reaching normal size.
(3), anneal, circle copper flexible cord is passed in annealing machine and carries out heating anneal.
(4) native copper flexible cord, is gone back, the hot copper flexible cord of annealed process directly enters reduction cooling agent service tank, by reduction cooling agent controller control dose, reduction reaction is carried out to hot copper flexible cord, removing cupric oxide, and hot copper flexible cord is cooled to close to normal temperature, now copper flexible cord temperature is lower than the condition of copper and oxygen reaction, no longer produces cupric oxide.
(5), take-up, admission machine is to reduce and the copper flexible cord of lowering the temperature reclaims, and pitch of the laps becomes to prick.
(6), product inspection, product is carried out to the inspection of quality.
The model of the equipment wire drawing machine adopted in the technique of reduction cooling agent reduction copper conductor of the present invention: Z17 or LHD3-400/13 type, the model of annealing machine: T2000, the model of admission machine:
S630。
