器用電線に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electric wire with excellent acoustic effects. More specifically, a single crystal or a very small number of crystals produced by a heated mold continuous casting method can be produced by processing a wire material having a unidirectional solidification structure that grows only in the length direction of the wire. Regarding electric wires for audio equipment.

。When metal ingots, which are the raw materials for electric wires, are made by the conventional cooling mold method, columnar crystals develop from the outer periphery almost perpendicular to the ingot surface, and in the center of the ingot, columnar crystals are formed during solidification. It is known that impurities tend to accumulate and cause macro-segregation, as well as cavities and bubbles. When an ingot with such internal defects is made into an electric wire by rolling, extrusion, or drawing, the electric wire is made up of many fine crystals.
素材の鋳塊中に存在した鋳巣、気泡、偏析は分散し微細
に分布して、電導線中にいわゆる微視的欠陥を形成する
。これらの結晶粒界や微視的欠陥が電線の音響効果に著
しく影響することが知られている。The cavities, bubbles, and segregation present in the ingot of the material are dispersed and finely distributed, forming so-called microscopic defects in the conductive wire. It is known that these grain boundaries and microscopic defects significantly affect the acoustic effects of electric wires.

用いると信号伝送時のひずみが大幅に改善されることが
知られている。In other words, the grain boundaries of copper wire, which has traditionally been used as electric wire, take on the properties of a minute capacitor when current flows, weakening the audio signal current or shifting the two phases, distorting the acoustic effect. It is known that if the crystal grains are made larger, the number of crystal grain boundaries will be reduced, and therefore, if an electric wire drawn from this is used, distortion during signal transmission will be significantly improved.

た。Due to the coarsening of the crystal grains of copper wire, conventionally, wires made using oxygen-free copper with extremely low impurities were made at 90%
A method that has been used is to heat the wire in an inert gas furnace at a high temperature of 0 to 1000° C. for several hours to grow and coarsen the crystals, and then to stretch the wire to make an electric wire with a linear crystal structure.
このような方法では、結晶粗大化のための加熱処理に大
きなエネルギーと時間を費やさなければ渋らなかった。In such a method, it was necessary to spend a large amount of energy and time on heat treatment to coarsen the crystals.
しかも、結晶粒界の全くない単結晶の電線をうることは
できなかった。Moreover, it has not been possible to obtain a single-crystal electric wire with no grain boundaries.
本発明は、音響効果を低下させる結晶粒界や微小欠陥の
全くない電線を提供するものである。The present invention provides an electric wire that is completely free of grain boundaries and micro defects that reduce acoustic effects.

からなる電導線を極めて容易に供給することができる。In order to continuously produce ingots with no internal defects, the present inventor has developed a continuous heating mold type, which is characterized by maintaining the temperature of the inner wall surface of the mold for continuous casting of ingots at a temperature higher than the solidification temperature of the cast metal. He invented a casting method (Japanese Patent No. 1,049,146) and succeeded in continuously obtaining perfect unidirectionally solidified ingots with no equiaxed crystals. The ingot obtained by this method has no cavities, bubbles, or center segregation inside. Furthermore, according to this method, a single crystal ingot or a directionally solidified ingot consisting of a very small number of crystals can be easily obtained. Therefore, the ingot obtained by using the heated mold continuous casting method (3) Procedure Amendment (Method) has good workability and can be easily processed into fine wires, as well as being a single crystal with no grain boundaries. It is very easy to supply a conductive wire consisting of:
