METHOD OF PRODUCING AN OXYGEN-FREE COPPER WIRE MATERIAL BY A CONTINUOUS CAST-ROLLING METHOD USING A ROTATIONAL MOVABLE MOLD

摘要

A method of producing an oxygen-free copper wire material, containing: continuously guiding a molten copper obtained by melting electric copper, into a tundish through a conduit; injecting the molten copper in the tundish, into a rotational movable mold; cooling and solidifying the molten copper, to form an ingot; and continuously drawing the ingot out of the mold, followed by continuous rolling; the method further containing: allowing the molten copper in the conduit to react with a solid reducing agent, under blowing an inert gas thereinto; allowing the molten copper in the tundish to react with a solid reducing agent, under blowing an inert gas thereinto; and adding a phosphorus compound to the molten copper, so that the phosphorus content in the ingot would be from 1 to 10 ppm; and controlling the temperature of the molten copper in the tundish from 1,085 to 1,100° C.
