为了降低轧制带材时的轧制力和功,在相当长的时期内,采用各种类型的小直径工作辊的多辊式轧机,使用大的带材张力,改进润滑剂的效用等方法,以提高变形效率。此外,对单辊传动条件下的异步轧制及其轧制力和扭矩问题进行了研究。直到七十年代初期,B.H.维德林和Л.М.阿盖耶夫研究成功了所谓“拉伸—轧制”的异步轧制新原理。此后,各国相继进行了大量试验研究工作,尤其是在冷轧方面,已显出一定的生命力。八十年代初期,日本石川岛播磨重工业公司研究出在一般四辊轧机上仅改变上下工作辊
In order to reduce the rolling force and work force during rolling of the strip, a method of using a multi-roll mill of various types of small-diameter work rolls for a long period of time, using a large strip tension and improving the effect of a lubricant , In order to improve the deformation efficiency. In addition, the single-roller transmission under the conditions of asynchronous rolling and rolling force and torque problems were studied. Until the early seventies, B.H. Widlin and Л.М. Agayev successfully succeeded in the new principle of so-called “stretch-rolling” asynchronous rolling. Since then, various countries have carried out a large number of experimental research work, especially in the cold-rolled area, has shown some vitality. In the early 1980s, Japan’s Ishikawajima Broadcasting Heavy Industries Co., Ltd. developed in the general four-roll mill only to change the upper and lower work roll
