Description
Technical field
The present invention relates to a kind of fine rule, many metal composite of glass-coated microwire wire rod and preparation method thereof, especially relate to fine rule, glass-coated microwire composite wire and the manufacture method thereof of a kind of " copper covered steel ".
Background technology
At present, for replacing pure copper wire, solve copper resource scarcity, defect of high cost, " fine rule, many metal composite of glass-coated microwire wire rod " technology is in continuous development, especially also a lot of about the relevant introduction of the fine rule of copper covered steel, glass-coated microwire composite material, but pure cu conductor exists density big, and weight is big, is difficult for defectives such as laying; And substitute material carbon steel conductor exists conductance relatively poor, mechanical strength is on the low side, flexible poor, welding performance is poor, defectives such as contact resistance is big, therefore, if will alleviate wire weight, the more copper product of saving reduces cost, and the substitute material percentage by weight is excessive will to have influence on final electric conductivity of composite material and comprehensive mechanical performance etc., can't satisfy performance requirement, and if satisfy performance requirement, the copper layer that coats in the prior art is often thicker again, and the percentage by weight of copper is still very big, still can't reach the saving copper product, the intended purposes that reduces cost, therefore, how to make full use of these materials advantage separately itself, it is organic in conjunction with a difficult problem that is the puzzlement people always.
On the other hand, the traditional view of preparation composite wire is thought: fine copper is not suitable for quenching, quenching can make copper hardness improve, think that drawing procedure must directly could guarantee comprehensive mechanical performances such as its tensile property and ductility by annealing in process, the method of therefore traditional manufacturing " many metal composite wire rod " generally adopts is to carry out " annealing in process " to guarantee its tensile property and to have preferably comprehensive mechanical performance such as ductility after drawing procedure, but " annealing in process " of available technology adopting is in any case operation is set treatment conditions, the comparatively perfect performance that all can't obtain to expect, the properties of product of final acquisition neither be very desirable.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of in light weight, tensile strength, electric conductivity, all comparatively desirable fine rule, many metal composite of the glass-coated microwire wire rod of comprehensive mechanical performance are provided.
On the other hand, the present invention overcomes the technology prejudice that exists in the prior preparation method, a kind of method for preparing fine rule, many metal composite of glass-coated microwire wire rod that has increased Quenching Treatment is provided, thereby has improved the performance of fine rule, many metal composite of glass-coated microwire wire rod greatly.
The technical solution used in the present invention is as follows:
Fine rule of the present invention, many metal composite of glass-coated microwire wire rod are made up of core body and coating layer, core body is a carbon steel wire rod, coating layer is the copper strips of purity more than 99.6%, metallurgical binding is passed through at the interface of core body and coating layer copper strips, wherein the section thickness of coating layer copper strips is 0.0031～0.1014mm, and the weight of coating layer accounts for 23.6～35.6% of composite wire total weight.
Preferably, the cross-sectional area of coating layer accounts for 14.90～15.12% of the total cross-sectional area of composite wire.
The resistivity of composite wire is 0.04310～0.05747 Ω/cm3.
Composite wire proportion is for being 8.02～8.15g/cm3.
Composite wire tensile strength is 700～760Mpa.
Preferred, when composite wire was circular wire rod, its line directly was 0.08～2.60mm.
On the other hand, the present invention also provides a kind of method for preparing fine rule, many metal composite of glass-coated microwire wire rod, and this method comprises the steps:
A, the method for using machinery or chemical industry to handle, removing carbon steel wire rod core body and purity is the grease and the oxidation passivation layer of the copper strips cover surface more than 99.6%;
B, the copper strips coating layer is coated on the carbon steel wire rod core body makes composite blank, wherein the weight of coating layer accounts for 23.6～35.6% of composite wire total weight;
C, drawing typing are drawn to the required diameter scope with composite blank and form composite wire, and wherein the coating layer section thickness is 0.0031～0.1014mm;
D, Quenching Treatment, in the described Quenching Treatment process, composite wire is 800～2500m/min by the translational speed of treatment fluid, cooldown rate is 0.3～0.6 ℃/min;
E, annealing softening are handled, and obtain final products.
Fine rule of the present invention, many metal composite of glass-coated microwire wire rod, setting coating layer copper strips section thickness and weight by resultant, the superior function of various materials is organically combined, solved a difficult problem of the prior art, thereby a kind of fine rule lighter, many metal composite of glass-coated microwire wire rod have been obtained than prior art weight, when alleviating composite wire weight, guaranteed that again its tensile strength, electric conductivity, comprehensive mechanical performance are all comparatively desirable.
On the other hand, the present invention overcomes the technology prejudice that exists in the prior preparation method, by increasing this operation of Quenching Treatment, thereby guarantee that fine rule of the present invention, many metal composite of glass-coated microwire wire rod are under the prerequisite that alleviates composite wire weight, still can guarantee that its tensile strength, electric conductivity, comprehensive mechanical performance are all comparatively desirable, meet the correlated performance requirement fully.
