Patent

CA 2337670

An apparatus for manufacturing a copper wire 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 can be obtained having superior surface quality. An apparatus for continuously manufacturing ingots of low-oxygen copper comprises a melting furnace in which combustion is performed in a reducing atmosphere so as to produce molten copper; a soaking furnace for maintaining a predetermined temperature of the molten copper supplied from the melting furnace; a casting trough for sealing the molten copper supplied from the soaking furnace in a non-oxidizing atmosphere and for transferring the molten copper to a turn-dish; a degassing means provided in the casting trough for dehydrogenating the molten copper passing therethrough; a continuous casting machine for continuously producing cast copper from the molten copper supplied from the turn-dish, and a cutting means for cutting the cast copper into a predetermined length.
