MANUFACTURING METHOD FOR COPPER WIRE AND MANUFACTURING APPARATUS THEREFOR

Japanese Patent JP3651386

B2

PROBLEM TO BE SOLVED: To provide a manufacturing apparatus a copper wire not producing many halls during solidification and performing dehydrogenation without securing long transfer distance, and to obtain a low oxygen copper wire having superior surface quality.
SOLUTION: In the manufacturing apparatus 1 for the copper wire in which molten copper is supplied to a continuous casting machine D and in which bar like copper material fed from the continuous casting machine D is then rolled into the low oxygen copper wire, the manufacturing apparatus is provided with a melting furnace A producing molten copper while burning in an reducible atmosphere, a heat-retaining furnace B retaining molten copper fed from the melting furnace A at predetermined temperature, a casting gutter C feeding molten copper sent from the heat-retaining furnace B to a tundish 5 while molten copper is sealed in a non-oxidized atmosphere, and a degassing means 33 dehydrogenating molten copper passing through the casting gutter C.
