摘要

本文主要是利用實驗探討試片經非對稱壓延加工後，其試片的輥輪壓延力、壓延扭矩及彎曲曲率分別於不同縮減率時的變化情形。實驗條件以同徑異周速為主，包含輥輪與壓延試片間的界面摩擦及入口試片厚度不同等。
藉由本實驗所規劃的加工條件，可得知壓延後之試片曲率受縮減率大小、圓周切線速度不同步、界面摩擦及試片初始厚度不同等條件的影響，試圖找出曲率值介於±0.0025(1/mm)內的臨界縮減率（即壓延後的成形試片呈現接近平坦的狀態）產生的條件。藉以達到曲率控制，減少壓延道次，以期達到加工能量需求較低之經濟性製程。

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.
