Description of drawings
Description of drawings preferred implementation of the present disclosure, and combine the disclosed content of preceding text, be used to provide further understanding to technological purport of the present disclosure.Yet, should the disclosure be read as and be limited to these accompanying drawings.
Fig. 1 is the flow chart of method that illustrates the manufacturing aluminium alloy wire of the preferred embodiment for the present invention.
Embodiment
Below, will be described in detail preferred implementation of the present invention with reference to accompanying drawing.Before describing; At first to understand the term that uses in specification and the accompanying claims and be not to be read as the meaning that is limited on common and the dictionary; And should be based on allowing the invention people suitably to define the principle of term for carrying out best illustration, foundation is understood corresponding to the meaning and the notion of technical elements of the present invention.Therefore, the description that this paper proposes only is the preferred embodiment that is used for illustration purpose, and is not intended to restriction scope of the present invention, so will be appreciated that under the situation that does not depart from purport of the present invention and scope, can make other equivalent form of values or modification to it.
Aluminium alloy wire of the present invention can comprise Fe, Cu, Mg and the B as the Al of essential element and the effective alloying element of conduct.
Fe can improve the intensity of aluminium alloy wire under the situation that does not reduce conductance, this is because separated out most of Fe during the heat treatment when making aluminium alloy wire.Particularly, during the heat treatment when making aluminium alloy wire Fe separate out the growth that has suppressed crystal grain, therefore prevented the reduction of alloy strength.When the content of Fe was the 0.3 weight %～0.6 weight % of aluminium alloy total weight, this effect can highly significant.Thus, when the content of Fe surpassed 0.6 weight %, conductance obviously descended, and when Fe content during less than 0.3 weight %, it is not enough that this intensity improves effect.
During the heat treatment when making aluminium alloy wire, Cu can produce precipitate, for example Al-CuAl
2Thereby, improved the intensity of aluminium alloy wire.Particularly, the same with Fe, during the heat treatment when making aluminium alloy wire, Cu separates out the growth that also stops crystal grain, has therefore prevented the reduction of alloy strength.When the content of Cu was the 0.3 weight %～0.5 weight % of aluminium alloy total weight, this effect can highly significant.Thus, when the content of Cu surpassed 0.5 weight %, conductance obviously descended, and when the content of Cu during less than 0.3 weight %, was difficult to expect that this intensity improves effect.And 0.3 weight %～Cu of 0.5 weight % can increase the corrosion potential of aluminium alloy wire, thereby improves corrosion resistance.
The content of Fe is high more, and the degree that Cu causes conductance to descend rapidly is also high more.Therefore, when the content of Fe be 0.5 weight % or when higher, the content of Cu preferably is limited to 0.3 weight %～0.4 weight %.
Also can form compound even Mg content is less, therefore can under the situation that does not reduce conductance, improve the intensity of aluminium alloy wire, can also improve pliability simultaneously with Si.When using aluminium alloy wire, Mg can reduce the contact resistance between aluminium alloy wire and the binding post, thereby reduces electrical loss.When the content of Mg is 0.03 weight % of aluminium alloy total weight or more for a long time, these effects can highly significant.Yet excessive Mg can reduce conductance.Therefore, Mg content is limited to 0.06 weight % or lower.
During the heat treatment when making aluminium alloy wire, B can suppress grain coarsening, and can promote particularly separating out of following impurity of element, thereby improves intensity and prevent the decline of conductance.When the content of B was the 0.01 weight %～0.10 weight % of aluminium alloy total weight, these effects can highly significant.Thus, when the content of B surpasses 0.10 weight %, can produce intermetallic compound, cause the decline of conductance, when the content of B during, not enough so that reduce the element of conductance and separate out less than 0.01 weight %.
Aluminium alloy wire with above-mentioned composition has 61.6%IACS or higher conductance, and 125MPa or higher tensile strength.
And; Aluminium alloy wire of the present invention can further comprise 0.01 weight % or Ti still less, 0.01 weight % or V still less, 0.01 weight % or Cr still less and 0.01 weight % or Ni still less as impurity, and the total content of impurity can be preferably 0.1 weight % or still less.When content of impurities was not in this scope, impurity can cause conductance to descend rapidly.
Fig. 1 is the flow chart of method that illustrates the manufacturing aluminium alloy wire of the preferred embodiment for the present invention.Referring to Fig. 1, the method for the manufacturing aluminium alloy wire of the preferred embodiment for the present invention can comprise successively Pu Luopeizi technology (continuous casting and rolling) (S10), drawing (S20) and heat treatment (S30).
In continuous casting and rolling (S10), the raw material fusing that can under 750 ℃～900 ℃, make aluminium alloy wire to be making alloy melt, and can this alloy melt be cast aluminium alloy wires.In the case; The raw material of aluminium alloy wire comprises: as the Al of essential element; As Fe, the Cu of 0.3 weight %～0.5 weight %, the Mg of 0.03 weight %～0.06 weight % and the B of 0.01 weight %～0.10 weight % of the 0.3 weight %～0.6 weight % of alloying element, and as 0.01 weight % or Ti still less, 0.01 weight % or V still less, 0.01 weight % or Cr still less and the 0.01 weight % or the Ni still less of impurity.
The temperature range of alloy melt is to obtain to have a necessary condition of tiny microstructural casting.When the alloy melt temperature surpassed 900 ℃, the microstructure generation alligatoring of casting caused impact toughness to reduce, and when the alloy melt temperature is lower than 750 ℃, because melt is mobile relatively poor, is difficult to melt is injected casting mould densely.
Continuous casting and rolling can be substituted by continuous casting.
Preferably, the diameter of aluminium alloy wires is 8.0mm～15mm, and being applicable to building cable, yet the present invention is not limited to this.
In drawing (S20), the aluminium alloy wires of casting can reduce cross section through processing, has standard-sized aluminium alloy wire thereby process.
In heat treatment (S30), can be under 250 ℃～400 ℃ the aluminium alloy wires through drawing (S20) be carried out 2 hours～24 hours heat treatment.In 250 ℃～400 ℃ temperature range, the amount of separating out of alloying element can be optimized, so that conductance and intensity maximization.When heat treatment temperature was lower than 250 ℃, thermal effectiveness was not enough; When heat treatment temperature surpasses 400 ℃, the alloy structure deliquescing, and intensity reduces rapidly.In addition, when heat treatment time was less than 2 hours, thermal effectiveness was not enough, and when heat treatment time surpassed 24 hours, intensity reduced.
In order to confirm the character of the above-mentioned aluminium alloy wire of processing, processed the aluminium alloy wire of Fe, Cu, Mg and B with different content.For this reason, through 750 ℃～900 ℃ the alloy melt that comprises above-mentioned alloying element being carried out continuous casting and rolling, carrying out drawing with coil winder subsequently and under 250 ℃～400 ℃, heat-treat, prepared aluminium alloy wires.
