碩士 === 國立中央大學 === 機械工程研究所 === 97 === Due to the asymmetrical rolling can reduce rolling force and rolling torque that will make rolling process also flexible and variable. There are extreme advantages in application of rolling industry. The specimens will curvature after the asymmetrical rolling, the flat bending will reduce production quality and impact machine, for this reason, this paper use experiment to find out the critical point of curvature. This paper discusses rolling force, rolling torque and curvature ratio with different reduction at asymmetrical rolling. The experimental conditions include different flat thickness and interface between rolling and specimens by lubrication or dry friction. By experimental conditions can find out specimens that become curvature turn up or turn down behavior with different reduction, different rolling speed, interface friction and different flat thickness after rolling process. Try to find out the critical reduction that curvature between ±0.0025(1/mm), i.e. curvature is near zero. For the purpose of control the curvature and decrease rolling pass times that can reach lower economical production process.
