Definitions

  • the present invention relates to an improved process for obtaining copper wire from scrap.
  • copper wire consisting in the continuous casting of copper wire starting from cathode and a process for shaping copper wire starting from scrap.
  • copper wire is meant a wire preferably of 8 mm in diameter which may have a diameter greater and less than that indicated, obtained by hot rolling.
  • the wire obtained by said processes is specially applied to the constitution of electric wires.
  • the improved process which is the subject of the present invention substantially improves the two known processes described by combining them so that it uses scrap as a raw material and on the other hand it uses the continuous casting process as the process which starts from the cathode, so that 'it uses the positive aspects of both processes and eliminates their negative aspects.
