Apparatus for manufacturing low-oxygen copper |
摘要 |
An apparatus for manufacturing a copper wire includes a melting furnace in which combustion is performed in a reducing atmosphere so as to produce molten copper; a holding 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 holding furnace in a non-oxidizing atmosphere and for transferring the molten copper to a tundish; a degasser 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 tundish, and a cutter for cutting the cast copper into a predetermined length. The apparatus permits a dehydrogenating treatment to be performed without requiring a long moving distance of molten copper, and in which the generation of holes in solidification is suppressed, whereby high quality low-oxygen copper wire having superior surface quality can be obtained.
