本発明は、電線用導体として使用される圧縮型撚線用に
供されるアルミニウム荒引線に関するものである。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an aluminum rough drawn wire for compressed stranded wire used as a conductor for electric wires.
（背景技術）
近年、電線用導体としてＡＱ又はＡＱ合金を用いたアル
ミニウム（以下、単にアルミと称す）導体が使用されて
いる。アルミは軽量であるが、導電率が銅に比べ低い（
例、８１％ｌＡＣ３）ため、その占有断面積を小さくす

ルミ、鋼等より成り、その周りに複数本の扇形状のアル
ミ線２が１層以上撚り合わされている。(Background Art) In recent years, aluminum (hereinafter simply referred to as aluminum) conductors using AQ or AQ alloys have been used as conductors for electric wires. Aluminum is lightweight, but its conductivity is lower than that of copper (
For example, 81% lAC3) Therefore, in order to reduce the occupied cross-sectional area, it is often used in the form of a compressed stranded wire as shown in FIG. 1, for example. In the figure, reference numeral 1 denotes a centerline made of aluminum, steel, etc., around which one or more layers of a plurality of fan-shaped aluminum wires 2 are twisted.

なく、商品価値を低下する欠点があった。Such a compression-type stranded wire is produced by compressing it with a compression die 3 during stranding, as shown in FIG. At this time, as the aluminum wire 4, an aluminum wire drawn from continuous cast-rolled electrical aluminum wire is usually used, but when this continuous cast-rolled aluminum wire is used, during die compression, The compression die 3 generates aluminum powder and vertical creases occur on the conductor surface, making the stranded wire surface rough and unsuitable for use as a smooth conductor (smooth body), which can cause serious trouble in the next coating process. This has the drawback of not only causing problems, but also lowering the product value.

発生のない圧縮型撚線用アルミニウム荒引線を提供せん
とするものである。(Disclosure of the Invention) The present invention has been made to solve the above-mentioned problems, and is an aluminum roughening method for compression-type stranded wires that does not generate aluminum powder or vertical streaks on the surface during compression processing of stranded wires. It is intended to provide a guiding line.

る圧縮型撚線用アルミニウム荒引線である。The present invention provides a continuously cast and rolled aluminum rough-drawn wire for compression-type stranded wire produced by die compression, containing 0.005 to 0.05% MgO, and the remainder consisting of AQ and unavoidable impurities. This is a compression type aluminum rough drawing wire for stranded wire, which is characterized by being made of an alloy.

率が６１％ｌＡＣ３に達せず、アルミ導体として使用で
きない。In the present invention, Mg in the AQ alloy is 0.005 to 0.
The reason for specifying 05% is to prevent the generation of aluminum powder and the generation of vertical streaks on the conductor surface during compression processing using a compression die for stranded wires.Although the mechanism is not clear, Mg is Because it segregates on the surface and forms oxides (MgO), which has inferior corrosion resistance compared to ordinary electrical aluminum, it is thought that fine pitting corrosion occurs on the surface, and wire drawing wire is trapped there. . If Mg is less than 0.005%, the above-mentioned improvement effect will not be obtained, and if it exceeds 0.05%, the conductivity of aluminum will not reach 61% lAC3, and it cannot be used as an aluminum conductor.

圧縮加工されて圧縮型撚線に仕上げられる。In the present invention, the aluminum rough drawn wire is manufactured by normal continuous casting and rolling, and after being drawn into aluminum wire by a normal method, it is twisted together, and at the same time, it is compressed with a compression die to become a compression type stranded wire. It will be finished.

For example, it may be a steel-core aluminum stranded wire, an aluminum stranded wire, an aluminum-coated steel-core aluminum stranded wire, etc., and the number of strands is not limited to seven, and can be applied to any number.

表１より、本発明によるものは、従来例、比較例に比し

あることが分る。From Table 1, it can be seen that the conductor surface of the present invention was smooth, without the generation of aluminum powder in the compression die, compared to the conventional example and the comparative example.
これに対し、従来例、Ｍｇｆｆ１の少ない比較例はアル
ミ粉の発生多く、がっ表面悪＜ 、Ｍｇ 量の多い比較
例は良好であるが、導電率が下がり、実用できない。On the other hand, the conventional example and the comparative example with a small amount of Mgff1 generate a lot of aluminum powder, and the surface has a bad surface.The comparative example with a large amount of Mg is good, but the conductivity decreases and it cannot be put to practical use.
