Below, the present invention is illustrated in further detail.
＜Sn: greater than 0.5 quality % and between the 0.8 quality % 〉
The amount that makes Sn is greater than 0.5 quality %, be in order to obtain more high-intensity pole line raw material, and the amount that makes Sn is in order to suppress the reduction of electric conductivity more below 0.8 quality %.
＜Ag, In, Sr, Ca, Mg, Zr's is at least a: total amount is 0.0005～0.3 quality % 〉
By in copper, adding at least a of Ag, In, Sr, Ca, Mg, Zr, can improve the intensity of copper alloy, even and because of the electric arc between pantograph and pole line generates heat, can not make copper alloy softening yet, can improve thermotolerance.
If above-mentioned Ag etc. add total amount less than 0.0005 quality % of element, then intensity and stable on heating last ascending effect are limited.And though Ag under situation about existing with metal form, has the electric conductivity higher than copper, when Ag carried out solid solution in copper alloy, the electric conductivity of copper alloy descended.So, make these total amount upper limits of adding element below 0.3 quality %, can prevent that the lead rate of pole line from descending.And by adding these elements, the casting sheet slight crack in the time of can preventing the casting of pole line raw material can suppress broken string in addition in the wire drawing engineering of pole line manufacturing stage.
＜oxygen: 0.01～0.05 quality % 〉
By making the oxygen amount is 0.01～0.05 quality %, can obtain necessary electric conductivity like a cork.And, by the oxygen level of the employed cast material of manufacturing that makes pole line more than 0.05 quality %, but the generation of inhibited oxidation copper and is suppressed at that to add man-hour be the broken string of starting point with the cupric oxide.Otherwise,, be difficult to obtain high-quality pole line in the engineering after casting if oxygen amount less than 0.01 quality % then is easy to generate slight crack during hot-work.
In the chemical ingredients of pole line of the present invention, also can contain unavoidable impurities.Unavoidable impurities comprises Ni, Sb, As, Fe, Pb, Bi, P, Si, Zn, S, Se, Te etc.

2The time at 500N/mm
2More than, be 170mm with basal area
2The time at 460N/mm
2Below comparatively suitable.
＜electric conductivity: more than the 60%IACS 〉
More than 60%IACS, can satisfy necessary electric conductivity by the electric conductivity that makes pole line as pole line.Though in pole line of the present invention, Sn concentration height, difficult obtaining high conductivity, as and do not require the interchange pole line of so high electric conductivity, pole line of the present invention is still suitable.This electric conductivity is represented with the per-cent (%IACS) to the electric conductivity of the standard annealed copper of international annealed copper standard defined 20 ℃ the time.
＜utilize continuous casting to obtain the engineering of cast material 〉
The engineering that obtains cast material is good with the forging type that rotates belt (wheel belt) mode and two movable molds of this use of belt (twinbelt) mode.Cast continuously by utilizing these modes, can suppress manufacturing cost.
＜cast material is imposed hot-work and obtain the engineering of wire rod
Hot-work by cast material being imposed under the temperature more than 600 ℃ more than 50% can make cast structure's miniaturization, and improves wire rod intensity.Is good as hot-work with hot rolling.Particularly carry out hot rolling continuously mutually with aforementioned casting, preferable aspect manufacturing.
By making processing temperature, can carry out hot-work like a cork more than 600 ℃.And the processibility in the time of also can making the back engineering be cold working improves.Oxidation takes place in when calendering in cast material, reduces so impregnated in when the engineering of back in the alcohol etc.When the time comes, if the cast material cooling, then reaction is difficult to carry out, and reduction becomes slow, so from this point, it also is important more than 600 ℃ that processing temperature is remained on.
By making hot worked deformation extent, can make the crystal structure miniaturization of wire rod and improve intensity more than 50%.This deformation extent is represented with [basal area before (basal area after the basal area-processing before the processing)/processing].By adding above-mentioned interpolation element,, also can obtain the pole line of sufficient intensity by the cold working of back engineering even improve the thermal distortion degree to greatest extent.In addition, hot worked deformation extent is more than 70%, and can be more than 80%.
And, be more than the 20mm by the diameter of the wire rod of hot-work gained.By forming this gauge or diameter of wire, in next engineering, can accept the cold working of high deformation extent.As a result, can make the effect of utilizing cold worked wire rod intensity to improve more remarkable.By the diameter of the wire rod of hot-work gained, also can be more than 24mm.
＜wire rod is imposed cold worked engineering 〉
Obtain under the temperature below 150 ℃, imposing cold working after the above wire rod of diameter 20mm with the deformation extent more than 50%.Utilize this cold working, the intensity of wire rod is improved.The deformation extent is here also represented with [basal area before (basal area after the basal area-processing before the processing)/processing].Utilize this cold working, can obtain high-intensity pole line.
Cold working is fit to Wire Drawing.Processing temperature is getting final product below 150 ℃, also can not heat at normal temperatures and processes.Deformation extent is more than 50%.By carrying out the cold working of deformation extent more than 50%, can obtain enough intensity and improve effect.This deformation extent to be being good more than 70%, more than 75% for better.
Below, example of the present invention is described.
Engineering according to fusion → casting → hot rolling → wire drawing → goods is made pole line.In this project,, utilize the continuous casting rolling equipment to process from fusing to hot rolling.At first, the fusion copper alloy of the chemical ingredients shown in the continuous casting table 1.Then, carry out hot rolling and obtain wire rod with the deformation extent shown in the table 2.Then, to resulting wire rod, impose cold drawn silk processing with the deformation extent shown in the table 2 equally, obtaining basal area is 170mm
