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.
