本文试图通过“搓轧区”的形成,异步轧制过程的建立说明异步轧制的实质,导出异步轧制时的张力值及轧制压力的近似计算式。一“搓轧区”的形成:异步轧制由于上下轧辊线速度之差,改变了原来“同步轧制”时金属变形的应力状 In this paper, we try to illustrate the essence of asynchronous rolling through the formation of “rolling zone” and the establishment of asynchronous rolling process, and derive the approximate calculation formula of tension value and rolling pressure during asynchronous rolling. A “rubbing rolling zone” formation: asynchronous rolling due to the difference between the upper and lower roll linear velocity, changed the original “simultaneous rolling” deformation of the metal stress
