WIRE SOFTENING APPARATUS AND WIRE SOFTENING METHOD

摘要

A softening apparatus includes a cooling liquid reservoir for holding a cooling liquid, a first conducting sheave provided outside of the cooling liquid reservoir for applying a voltage to a wire while guiding the wire, and a second conducting sheave provided in the cooling liquid reservoir for letting a current flow through the wire while guiding the wire as the wire is fed via the first conducting sheave. The softening apparatus is also provided with a liquid level detector for detecting a liquid level of the cooling liquid in the cooling liquid reservoir. A heating path length of the wire between the first conducting sheave and the second conducting sheave is controlled based on a result of detection by the liquid level detector.
