Process for producing spheroidized wire rod |
摘要 |
A process for producing a wire rod for cold forging comprising: rapidly cooling the wire rod after hot rolling so as to give a rapidly cooled structure to the wire rod and to form a predetermined thickness of scale on the wire rod; and subjecting the rapidly cooled wire rod with the scale to spheroidizing annealing in an inert gas containing 0.1% or less moisture.
