Description
Technical field
The present invention relates to make the method for aluminium alloy wire, more particularly, relate to a kind of manufacturing and have improved conductivity and stable on heating aluminium alloy wire, its technology obtains simplifying by carry out the two levels of thermal processing after cold working.
Background technology
At present, be divided into overhead mode transmission and underground mode transmission from power plant or transformer station to the method for city or big Factory Electricity Supply, overhead mode transmission accounts for about 90% of domestic electric power transfer.
Here, be about 62% without any the conductivity of the fine aluminium of doped chemical, because fine aluminium is too soft, so,, also will add a small amount of doped chemical to it although can make the conductivity deterioration in order to strengthen intensity.
With regard to the technological trend of the aluminium alloy wire that is used for overhead transmission cable, in generation nineteen sixty, conductivity is that 60%IACS and continuous operation temperature are that 150 ℃ 60TAL (hot aluminium (ThermalALuminum) alloy wire) is a main flow, in the 1980's, conductivity is that 58%IACS and continuous operation temperature are that 230 ℃ XTAL (special hot aluminium (eXtra Thermal ALuminum) alloy wire) is a main flow, in 1985, conductivity is that 60%IACS and continuous operation temperature are that 210 ℃ STAL or ZTAL (superthermal aluminium (Super Thermal ALuminum) alloy wire) is main flow, and in 1993, conductivity was that 58%IACS and continuous operation temperature are that 230 ℃ XTAL is a main flow.
Here, " %IACS " is conductivity unit, and referring to resistivity is 100/ (58 * x) Ω mm
2/ m.
In addition, conductivity is relevant with the current strength (amperage) that can flow on the identical aluminium conductor of sectional area.That is to say that higher conductivity means can flow through more multiple current, thereby has increased transmittability.
In addition, stream time is also referred to as heat resisting temperature.If electric current flows through aluminium conductor, then the resistivity owing to conductor produces heat.At this moment, if produced heat, then various metals all deliquescing also are elongated subsequently.Therefore, if heat resisting temperature improves, though then flow through high electric current, intensity does not change.In addition,, then can improve transmittability, and not have any loss of strength that causes owing to heating if heat resisting temperature improves.
In the superincumbent technological trend, determine transmittability according to conductivity and continuous operation temperature.For example, suppose that conductivity is that 60%IACS and continuous operation temperature are that the transmittability of 210 ℃ STAL is 1, then for identical sectional area, conductivity is that 58%IACS and continuous operation temperature are that the transmittability of 230 ℃ XTAL is 1.13, and this has improved about 13%.Therefore, in order to improve the transmittability of overhead transmission cable, need to improve conductivity and continuous operation temperature, i.e. conductivity characteristic and thermal endurance.
Yet, in the relation of elevated temperature strength, be difficult to guarantee simultaneously elevated temperature strength and high conductivity according to conductivity and continuous operation temperature.Usually, if elevated temperature strength strengthens, then conductivity reduces.Therefore, in order to improve this two key elements, must be optimized process conditions.
In addition, if add any doped chemical to aluminium, then the conductivity of aluminium reduces.Therefore, in order to increase the conductivity of Al-Zr aluminium alloy wire, need from aluminium matrix (matrix), extract doped chemical.In addition, in order to improve the continuous operation temperature,, that is, there is not the structure of crystallization again even aluminium alloy should have at high temperature also immovable structure.

Here, at Japan Patent the 5th, 070, in No. 905, use method manufacturing shown in Figure 1 to have improved conductivity and stable on heating aluminium alloy wire.
With reference to Fig. 1, for make conductivity be 59% or above and continuous operation temperature be 230 ℃ or above aluminium alloy wire, need following technology: " casting (S10) → hot working (S20) → first cold working (S30) → first heat treatment (S40) → second cold working (S50) → second heat treatment (S60) ".At this moment, form wire rod (wire rod) by continuous casting and backing (roll) technology (S10 to S20).In addition, at first with 50% or higher cross section reduction rate wire rod is carried out cold working to form first rapidoprint (S30).Then, at first in 300 ℃ to 450 ℃ temperature range with the first rapidoprint heat treatment 5 to 50 hours (S40).Subsequently, then with 50% or higher cross section reduction rate carry out second cold working to form second rapidoprint to having experienced first heat treated first rapidoprint.Then, follow in 350 ℃ to 500 ℃ temperature range the second processing line heat treatment 0.5 to 10 hour.
Yet, Japan Patent the 5th, 070,905 method is added beryllium and is strengthened elevated temperature strength, but beryllium is environmentally harmful material, therefore can cause environmental problem and increase production cost.In addition, because after casting and hot-cast fabrication technique, carried out twice cold working and heat treatment respectively, so above manufacture method is complicated.
In addition, this is used for the high continuous operation temperature that the improved stable on heating aluminium alloy of having of overhead transmission cable has 230 ℃, but has only 58% to 59% low conductivity.

Hereinafter, describe the preferred embodiments of the present invention with reference to the accompanying drawings in detail.Before explanation, should be appreciated that, the term that uses in specification and appended claims should not be construed as limited to general and dictionary meaning, but should be based on following principle based on making an explanation with the corresponding meaning of technical elements of the present invention and notion, described principle is: allow the inventor suitably to define term to make an explanation best.Therefore, just only for the preferred exemplary of illustration purpose, rather than to limit the scope of the invention, therefore should be appreciated that, under the situation that does not break away from the spirit and scope of the present invention, can draw other equivalents and modified example in the description of this proposition.
Mainly made of aluminum according to aluminium alloy wire of the present invention, and to its interpolation material (such as zirconium, iron and silicon).
The zirconium is-symbol is that Zr, atomic number are 40, atomic weight is 91.22, proportion be 6.51 and fusing point be 1,850 ℃ transition elements, the content of the zirconium of interpolation be preferably whole aluminium alloy weight 0.2% to 0.4%.In the case, thermal endurance and ductility reduce when zirconium content leaves above scope, and therefore, above content range is best.
In addition, zirconium is used for reducing subtly the particle of aluminium alloy, thereby improves elongation.
The iron is-symbol is that Fe, atomic number are 26, atomic weight is 55.847, proportion be 7.86 and fusing point be 2,750 ℃ transition elements.The content of the iron that comprises in the present embodiment, be preferably whole aluminium alloy weight 0.05% to 0.2%.In the case, corrosion resistance and tensile strength reduce when iron content leaves above scope, and therefore, above content range is best.
In addition, iron is the key element that is used for being controlled at the growth of the precipitation that the aluminium matrix produces, and therefore, iron has prevented: thus the particle in the aluminium matrix increases rapidly and makes the elongation deterioration.
The silicon is-symbol is that Si, atomic number are 14, atomic weight is 28.086, proportion be 2.32 and fusing point be that 1,410 ℃, boiling point are 2335 ℃ nonmetalloid.The content of the silicon that comprises in the present embodiment, be preferably whole aluminium alloy weight 0.05% to 0.2%.In the case, thermal endurance and tensile strength reduce when silicone content leaves above scope, and therefore, above content range is best.
In addition, silicon is used for increasing the flowability of deposite metal during the casting of aluminium alloy is handled, and silicon is also taken on the nuclear (nucleus) of the precipitation that produces in casting and cooling period in the aluminium matrix.
At this moment, extremely low if iron content is compared with silicone content, thus the particle that then forms in the aluminium matrix can increase the elongation deterioration that makes aluminium alloy rapidly.In addition, high if iron content is compared with silicone content, then the diffusivity of the silicon atom in the aluminium matrix is understood deterioration, thereby can't improve thermal endurance.Therefore, iron and silicon alloy element sum preferably are not more than 0.3% of whole aluminium alloy weight.
Now, explain the manufacture method of the aluminium alloy wire of making by above according to the preferred embodiment of the invention material with high conductivity and high-fire resistance with reference to Fig. 2.
With reference to Fig. 2, at first, the material with aluminium alloy wire in 750 ℃ to 900 ℃ scope is cast into molten state, in 450 ℃ to 550 ℃ temperature range it is carried out backing to form Birmasil line (being wire rod shape) (S100) then.Afterwards, with 70% or higher cross section reduction rate (sectional reduction ration) this Birmasil line is carried out hot working to form first aluminium alloy wire (S200).

In addition, the casting temperature scope of deposite metal is set to obtain solid solution.At this moment, if the casting temperature of deposite metal is above 900 ℃, the then fine structure of foundry goods meeting roughening, thereby can not improve impact toughness, yet, if casting temperature is lower than 750 ℃, mistake casting (miss run) phenomenon then can take place, wherein the deposite metal is not filled casting space densely owing to lack mobile.Therefore, the casting temperature of deposite metal is best in 750 to 900 ℃ scope.
In addition, top backing temperature range helps more easily to process foundry goods.In addition, this temperature range has limited the growth of particle in the aluminium matrix.At this moment, if the backing temperature surpasses 550 ℃, thereby then because particle during backing such as particles fuse understands roughening and structure can be subsided.Simultaneously, if the backing temperature is lower than 450 ℃, then backing ability is deterioration greatly.Therefore, backing temperature is best in 450 to 550 ℃ scope.
In the present embodiment, the diameter of first aluminium alloy wire is 9.8mm Φ, and can process the hot working of carrying out among the step S200 by continuous casting and backing.Yet, the invention is not restricted to this.
After step S200, first aluminium alloy wire is carried out cold working to form second aluminium alloy wire (S300) with the cross section reduction rate in 85% to 90% the scope.
Here, cold working makes the particle miniaturization that forms by step S100 to S200, and increases the intensity of aluminium alloy.
In addition, cold working is designed to alloying element is remained solid solution to satisfy the extraction conditions of explaining after a while in the aluminium matrix.That is to say that cold working provides the place of nuclear of the precipitation of the produced alloying element in the aluminium alloy, energy is introduced the aluminium matrix, and make this energy become the actuating force that causes precipitation.
By Al
3The precipitation of Zr has been improved the conductivity according to aluminium alloy wire of the present invention.That is to say that by step S100 to S300, aluminium element and zr element form compd A l
3Zr is because Al
3Thereby the homogeneous precipitation of Zr has improved the conductivity of aluminium alloy.
Therefore, the cross section reduction rate among the step S300 is restricted to 85% to 90% scope so that in the Technology for Heating Processing of describing after a while Al
3The precipitation capacity maximization of Zr.In addition, make Al
3The precipitation capacity maximization of Zr is to strengthen the conductivity according to aluminium alloy wire of the present invention.
After step S300, carry out two-grade aging (ageing) and handle (S400), it comprises: first heat treatment, (it is Al to be used to increase the distribution of nuclear of dislocation (dislocation)
3The nucleation place of Zr); With second heat treatment, be used to optimize Al
3The precipitation capacity of Zr.
Keep realizing in 15 to 30 hours first heat treatment by second aluminium alloy wire down at 250 ℃ to 350 ℃ with step S300.Here, temperature and time is set to optimum range, and this scope makes can increase the nucleation place of the precipitation of introducing by the cold working of step S300, thereby produces a large amount of precipitations pro rata with the nucleation place that is increased.
At this moment, take out Al between the granule boundary from the aluminium matrix
3Zr extracts it then.Simultaneously, because precipitation is formed on the granule boundary place, thereby increased hardness.
Keep realizing in 50 to 80 hours second heat treatment by experiencing the first heat treated aluminium alloy wire down at 300 ℃ to 450 ℃.At this moment, Al
3The precipitation capacity of Zr is optimised by first heat treatment.
In the present embodiment, if Al
3The precipitation capacity of Zr is little, can't improve thermal endurance, yet, if Al
3Thereby the size of Zr particle spreads in the aluminium matrix greatly unevenly, then makes the thermal endurance deterioration.Therefore, in the superincumbent temperature and time scope aluminium alloy wire is carried out second heat treatment so that the Al that is extracted
3Zr can spread in the aluminium matrix equably with the particular form through optimizing.
The aluminium alloy wire of making according to the present invention by above manufacturing process (especially step S300 to S400) thus best multiple element being become alloy in the aluminium matrix has improved conductivity.In addition, the precipitation in the aluminium matrix has upset and has constituted the motion of the particle of aluminium alloy wire, thereby has limited particle crystallization again when conductor temperature increases.In addition, even because at high temperature do not change existing structure yet, thus can improve the continuous operation temperature, that is, and thermal endurance.
For the characteristic of the aluminium alloy wire by above technology manufacturing is measured, in above ratio zirconium, silicon and iron are added in the aluminium that purity is 99.8 weight %, with this mixture dissolving, be made into the bar shaped that diameter is 9.8mm Φ by continuous casting and backing then.Afterwards, by step S300 to S400 this is made aluminium alloy wire.Then, use the double bridge method to measure the resistivity of aluminium alloy wire to obtain conductivity, then by its mechanical property of tension thermometrically.In addition, for the purpose of thermal endurance test, under 400 ℃ temperature,, be measured as thermal endurance before the heat treatment and the ratio of tensile strength afterwards with aluminium alloy wire heat treatment 4 hours.Listed measurement result in the table 1 below.
