Pass Redesign for Reduction of Wire Breakage in the Wet Wire Drawing Process

습식 신선공정의 단선율 저감을 위한 패스 재설계

The Production of fine wire through wet wire drawing process with appropriate pass schedule would be impossible without understanding of relationship among many process parameters. Therefore, this paper investigates the relationship among process parameters of wet wire drawing process. In this study, it is possible to obtain the important basic data that can be used in the pass schedule of multi-pass wet wire drawing process. In order to verify the effectiveness of the analysis, pass redesign was performed based on the result of analysis to reduce the wire breakage. The wire breakage between the conventional pass schedule and the redesigned pass schedule was compared by the FE analysis and the wet win drawing experiment.
