Abstract
Description
Technical field
The invention belongs to materials processing technology field, more specifically to a kind of high-strength highly-conductive pure copper wire material The preparation method of material.
Background technology
Fine copper has conduction very high, heat conductivility and plastic deformation ability higher, and with good corrosion resistance Can, it is widely used in industry as good conductor.However, although fine copper has the advantages that high conductivity, its tensile strength pole It is low, it is generally only 120-160MPa.In addition, fine copper has plastic deformation ability high, but because of its extremely low Static Recrystallization Temperature feature and cause easily processing hardening, so as to inhibit further plastic deformation.Therefore, pure copper material is applied to lead mostly Line, conductor and cooler etc., it is difficult to meet various application demands as structural material.General founding production fine copper electrical conductivity is high More than 95%ICAS, intensity is less than 250MPa, and using processing cure process, intensity can be brought up under 350MPa, but electric conductivity Drop, particularly elongation percentage are less than 5%, limit its engineer applied scope.Fine copper alloy is produced using powder metallurgy, usual 200 ~250MPa colds pressing under 800~900 DEG C of sintering process, and its electrical conductivity is less than 200MPa, elongation percentage in 80~90%IACS, intensity 25~30%, sintered more than 930 DEG C, then again under the complicated technology such as pressure finishing or forging, powder metallurgy fine copper performance can connect Nearly founding fine copper.
The conductance and tensile strength of the fine copper bulk prepared by right above-mentioned several method are still relatively low, it is impossible to meet certain The use of a little special occasions.
The content of the invention
1st, the problem to be solved
For the above-mentioned problems in the prior art, the present invention provides a kind of high-strength highly-conductive pure copper wire material Preparation method, it mainly solves two deficiencies of general industry copper conductor, 1, resistivity it is higher, 2, intensity it is not high, present invention system Preparation Method can be greatly improved the resistivity and intensity of copper conductor, have larger carrying to industrial robot energization communication conductor material property It is high.
2nd, technical scheme
In order to solve the above problems, it is an object of the invention to provide a kind of system of high-strength highly-conductive pure copper wire material Preparation Method,
In order to realize technical purpose of the invention, its technical scheme is：A kind of high-strength highly-conductive pure copper wire material Preparation method, it is characterised in that comprise the following steps：
（1）High-strength highly-conductive pure copper wire material is with high-purity catholyte copper that purity is more than 99.957% as base Body；
（2）Strict removal surface foul is simultaneously preheated to 80-100 DEG C；
（3）Using power frequency electromagnet smelting furnace melting, by melting, electromagnetic agitation integration, smelting temperature control 1150 ± 10 DEG C of scopes；
（4）By the molten copper liquid through power frequency electromagnet smelting furnace melting after complete by middle part transition warehouse from power frequency electromagnet melting To holding furnace, holding furnace takes electromagnetism to heat up, stirring, and between 1120-1130 DEG C, soaking time is its temperature control for stove overflow 1h；
（5）Drawn by high-precision servo motor and be drawn into the gauge copper wire bases of Ф 8.0, and crystallisation by cooling；
（6）Using continuous annealing wire drawing mode, annealing process temperature control is between 500-550 DEG C；
Electric conductivity and tensile strength using the pure copper wire material obtained by preparation method of the present invention can have both, tissue Uniformly, precipitated phase small and dispersed, alloy is cheap, and its TR specifications specific insulation is≤0.01707 Ω cm3, and tension is strong Degree reaches more than 420MPa, can preferably meet the performance requirement of copper conductor in electronics industry.
3rd, beneficial effect
Compared to prior art, beneficial effects of the present invention are：
（1）Preparation method of the present invention can improve the electric conductivity of pure copper copper conductor；
（2）Preparation method product crystal boundary of the present invention is close to perfect hexahedron, it is ensured that lattice is complete, greatly reduces crystal A large amount of microdefects of interior generation, such as point defect and dislocation, intensity increase, and can have both electric conductivity and tensile strength, adapt to Industrial robot is powered, communication high conduction requirement, adapts to industrial robot high-frequency Working motion intensity requirement；
（3）Preparation method of the present invention also has the advantages that process is simple, with low cost, reasonable in design.
Specific embodiment
The present invention is further described below with reference to specific embodiment.
A kind of preparation method of high-strength highly-conductive pure copper wire material, comprises the following steps：
（1）High-strength highly-conductive pure copper wire material is with high-purity catholyte copper that purity is more than 99.957% as base Body；
（2）Strict removal surface foul is simultaneously preheated to 80-100 DEG C；
（3）Using power frequency electromagnet smelting furnace melting, by melting, electromagnetic agitation integration, smelting temperature control 1150 ± 10 DEG C of scopes, it is ensured that cathode copper fully melts and is well mixed；
（4）By the molten copper liquid through power frequency electromagnet smelting furnace melting after complete by middle part transition warehouse from power frequency electromagnet melting To holding furnace, holding furnace takes electromagnetism to heat up, stirring, and between 1120-1130 DEG C, soaking time is its temperature control for stove overflow 1h；
（5）Drawn by high-precision servo motor and be drawn into the gauge copper wire bases of Ф 8.0, and crystallisation by cooling；
（6）Using continuous annealing wire drawing mode, annealing process temperature control makes through drawing generation between 500-550 DEG C Copper cash processing hardening disappear, and generation crystallize again, product crystal boundary is close to perfect hexahedron.
Electric conductivity and tensile strength using the pure copper wire material obtained by preparation method of the present invention can have both, tissue Uniformly, precipitated phase small and dispersed, alloy is cheap, and its TR specifications specific insulation is≤0.01707 Ω cm3, is much better than Industrial circular copper wire is most high-grade≤0.01715 Ω cm3 requirements, tensile strength reaches more than 420MPa, far above industrial circle The requirement of copper cash >=389MPa, can preferably meet the performance requirement of copper conductor in electronics industry.
Schematical above that the present invention and embodiments thereof are described, the description is not restricted.So, if One of ordinary skill in the art is enlightened by it, in the case where the invention objective is not departed from, without creative design Go out frame mode and the embodiment similar to the technical scheme, protection scope of the present invention all should be belonged to.
