由於非對稱壓延可有效降低壓延力及壓延扭矩，使材料於壓延製 程安排上，更趨自由與多樣性，在壓延工業之應用上，具有極大之助益；但於非對稱壓延後之板材易產生彎曲現象而造成產品品質降低及設備損壞。 本文主要以實驗的方法，觀察A1050P鋁材接觸輥輪時之入口角度 不同，對壓延後之板材彎曲曲率的變化情形，探討曲率與上下輥輪切線速度比值、縮減率及界面摩擦條件之關係，並討論加工參數對壓延力和壓延扭矩之影響。期望藉由本文所得之實驗結果，可提供理論解析之驗證及非對稱壓延製程品質改善之參考。 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. This research mainly use experiment to observe curvature about aluminum flat A1050P at rolling mill with different concact entry angle after rolling, investigate curvature behavior with mismatch peripheral speed ratio, reduction, interface friction, also discuss rolling force and rolling torque with process parameter. The results will supply theory, numeral analysis and process quality improvement.
