Title:
METHOD FOR MANUFACTURING WIRE ROD, APPARATUS FOR MANUFACTURING WIRE ROD, AND COPPER ALLOY WIRE
Document Type and Number:
WIPO Patent Application WO/2008/029855
Kind Code:
A1
Abstract:
This invention provides an apparatus for manufacturing a wire rod, comprising a wire rod feeding device, a wire rod winding device, and a running annealing device provided between the wire rod feeding device and the wire rod winding device, in which an aging precipitation-type copper alloy wire rod is folded back along a passage and is passed. The apparatus for manufacturing a wire rod may further comprises an electric heating annealing device for raising the temperature of the aging precipitation-type copper alloy wire rod in tandem on the upstream side of the running annealing device. Another electric heating device for conducting solid solution treatment of the aging precipitation-type copper alloy wire rod may be further provided in tandem on the upstream side of the running annealing device. Alternatively, instead of the running annealing device, the electric heating device may be connected in tandem to constitute a running heating device for aging treatment. The use of these devices can realize the provision of an aging precipitation-type copper alloy wire having a diameter in the range of not less than 0.03 mm and not more than 3 mm.
