    摘要: A method for manufacturing a low-oxygen copper wire is provided, in which a dehydrogenating treatment can be performed without requiring 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. The method for continuously manufacturing ingots of low-oxygen copper from molten copper includes a step of performing combustion in a reducing atmosphere in a melting furnace so as to produce molten copper; a step of sealing the molten copper in a non-oxidizing atmosphere in a casting trough; a step of transferring the molten copper to a tundish by using the casting trough; a degassing step of passing the molten copper through a degasser provided in the casting trough so as to dehydrogenate the molten copper; a step of continuously feeding the molten copper to a continuous casting machine so as to continuously produce cast copper; and a step of cutting the cast copper into a predetermined length.

    摘要: An adhesion-resistant oxygen-free roughly drawn copper wire having an oxygen concentration of 1 to 10 ppm and a hydrogen concentration of 1 ppm or less, has a surface oxide film having a total thickness of 50 to 500 angstroms, in which 0.2 to 90% of the total thickness of the oxide film is Cu2O. The adhesion-resistant oxygen-free roughly drawn copper wire is prepared using a continuous casting process, in which the molten copper is agitated and dehydrogenated in a casting trough containing weirs, and the thickness of the oxide layer is controlled by alcohol cleaning the cast copper bar material prior to rolling.

    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.

    摘要: A method for producing copper alloy materials for molds for continuous steel casting and molds as produced by the method. The molds are highly resistant to thermal fatigue and are hardly cracked. To produce the materials, cast ingots of a copper-based chromium-zirconium alloy comprising from 0.2 to 1.5% by weight of Cr and from 0.02 to 0.2% by weight of Zr are heated at between 900.degree. C. and 1000.degree. C. for 30 minutes or longer and then rolled, while hot, at a reduction ratio of 60% or more to be at 850.degree. C. or higher at which the hot rolling is finished , and immediately after the hot rolling, these are rapidly cooled to 400.degree. C. or lower at a cooling rate of 10.degree.C./sec or more, and then aged at between 400.degree. C. and 520.degree. C. for from 1 hour to 5 hours.
