METHOD AND APPARATUS FOR SOFTENING METALLIC WIRE

摘要

PROBLEM TO BE SOLVED: To provide a method and an apparatus for softening a metallic wire having good heating efficiency and small energy loss. SOLUTION: The apparatus 3 for softening the metallic wire is provided with a softening furnace 30 covering the outer circumference of the conveyed metallic wire 9, by heating this metallic wire 9 in the softening furnace 30 to soften the metallic wire 9. This apparatus 3 for softening the metallic wire is provided with an over-heated water vapor generating device 31 for generating the over-heated water vapor and an introducing path 30c for introducing the over-heated water vapor from the over-heated water vapor device 31 into the softening furnace 30 to heat the metallic wire 9 with the over-heated water vapor filled in the softening furnace 30. Since the over-heated water vapor has large heat-capacity and high heat-conducting efficiency, the metallic wire 9 can rapidly be heated. COPYRIGHT: (C)2011,JPO&INPIT
