Abstract:	本文是以實驗探討板材之非對稱輥軋，在於不同輥輪周速比及縮減率下其輥軋力、輥軋扭矩和成形板材的彎曲曲率的變化情形。實驗條件為同徑不同周速比，並包含輥輪與板材間的界面摩擦狀態、初始板厚及平均輥輪直徑的不同等。於非對稱輥軋後之板材易產生曲率彎曲現象而造成產品品質降低及設備損壞。藉由本實驗所規劃的加工參數，可得知輥軋後板材曲率彎曲行為受縮減率、異周速比及介面摩擦等的影響趨勢，探討出板材在其加工參數下之平坦區曲率值±0.0025(1/mm)的條件。藉以達到曲率控制，減少輥軋道次，以其達到加工能量需求較低之經濟性制程。 This paper discusses rolling load, rolling torque and curvature ratio with different rolling speed ratio and reduction at asymmetrical rolling. The experimental conditions include different initial flat thickness and interface between rolling and specimens by lubrication or dry friction and average diameter of the different roller. By processing parameters 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 flat area that curvature between 0.0025(1/mm). For the purpose of control the curvature and decrease rolling pass times that can reach lower economical production process.
