Title:
PROCESS FOR PRODUCING OXYGEN-FREE COPPER WIRE ROD BY CONTINUOUS CASTING ROLLING PROCESS USING ROTATIONAL TRANSFER MOLD
Document Type and Number:
WIPO Patent Application WO/2007/015491
Kind Code:
A1
Abstract:
A process for producing an oxygen-free copper wire rod, comprising continuously
leading molten copper obtained by melting an electrolytic copper via a spout
into a tundish; casting the molten copper within the tundish into a rotational
transfer mold; cooling the same so as to attain solidification to thereby obtain
an ingot; continuously pulling out the ingot from the mold; and directly subjecting
the same to continuous rolling, wherein the molten copper is reacted with a solid
reducing agent in the spout and an inert gas is blown thereinto, and wherein in
the tundish, in addition to the reacting of molten copper with solid reducing
agent and the blowing of inert gas, not only is a phosphorus compound added to the
molten copper so that the phosphorus content of the ingot falls in the range of
1 to 10 ppm but also the temperature of the molten copper within the tundish is regulated
at 1085° to 1100°C.
