Verfahren zur Herstellung von Walzdraht aus Kupfer mit niedrigem Sauerstoffgehalt

摘要

An apparatus 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. An apparatus for continuously manufacturing ingots (23a) of low-oxygen copper comprises a melting furnace (A) in which combustion is performed in a reducing atmosphere so as to produce molten copper; a soaking furnace (B) for maintaining a predetermined temperature of the molten copper supplied from the melting furnace (A); a casting trough (C) for sealing the molten copper supplied from the soaking furnace (B) in a non-oxidizing atmosphere and for transferring the molten copper to a turn-dish (5a); a degassing means provided in the casting trough (C) for dehydrogenating the molten copper passing therethrough; a continuous casting machine (D) for continuously producing cast copper from the molten copper supplied from the turn-dish (5a), and a cutting means (E) for cutting the cast copper into a predetermined length.
