초고속 신선을 통한 고탄소강(0.75wt%C) 선재의 생산성 향상에 관한 연구
Improvement of Productivity for the high carbon steel wire(0.75wt%C) through the Superhigh Speed Drawing
- 발행 : 2007.05.30
초록
Generally, fine high carbon steel wire is produced using a multi-pass drawing process with speeds over 1000 m/min. The productivity of the wire drawing mainly depends on achieving the highest drawing speed without breaking the wire. In the multi-pass drawing, as the final drawing speed increases, the temperature rises several hundred Celsius. High temperature of wire increases the brittleness and leads to breaks. The objective of this study is to design pass schedule and wire drawing machine for superhigh speed. In the drawing experiment, it was possible to increase the productivity through the increase in final speed from 1100 m/min to 2000 m/min.
