Abstract

PURPOSE:To produce the titled wire suitable as the wire for an audio by prepg. the high pure copper wire contg. specific amounts of silver and sulfur and converted into single crystal. CONSTITUTION:A graphite mold 6 is attached on the bottom side face of a melting furnace 2 and a pure copper rod 3 is positioned into the pore of said mold 6 in such a manner that one end of the rod comes into the inner side from the charging side of molten metal 1 as about 1cm. The molten high pure copper in which the contents of copper and sulfur are each regulated to <=0.5ppm is then charged into the melting furnace 2 and the temp. in the furnace is risen to about 1,250 deg.C and retained. Water is furthermore passed into a cooling structural body 5 installed against the charging side of the molten metal and the rod of the solidified pure copper is applied to pulse drawing by the pure copper rod 3 to form the copper wire converted into the single crystal. In this way, the copper wire for sound by which an audio system having drastically good high-pitched tone can be obtd. is produced.
