Method for continuously producing low-oxygen copper wire

摘要

A method for manufacturing a low-oxygen copper wire (23b) is provided, in which a dehydrogenating treatment can be performed without ensuring a long moving distance of molten copper, and the generation of holes in solidification is suppressed, whereby high quality low-oxygen copper wire (23b) can be obtained having superior surface quality. The method for continuously manufacturing ingots (23a) of low-oxygen copper from molten copper comprises a step of performing combustion in a reducing atmosphere in a melting furnace (A) so as to produce molten copper; a step of sealing the molten copper in a non-oxidizing atmosphere in a casting trough (C); a step of transferring the molten copper to a turn-dish (5a) by using the casting trough (C); a degassing step of passing the molten copper through a degassing means provided in the casting trough (C) so as to dehydrogenate the molten copper; a step of continuously feeding the molten copper to a continuous casting machine (D) so as to continuously produce cast copper; and a step of cutting the cast copper into a predetermined length.
