1 前言轧辊串动的概念源于五十年代初期。首次报导的是在一套二十辊森吉米尔轧机上安装了四根可以轴向串动的锥形中间辊,紧接着研制出成组装配的卡盘式轧辊装置,该装置可由液压方法装入轧机窗口。此后,又发明了可配置十二辊、六辊、二辊的可变卡盘。轧辊串动的应用从此扩大到多辊轧机的设计中。以便用小的工作辊轧制超薄带钢。然而,工作辊弯曲在传统的四辊轧机上控制凸度和板形仍起主要作用,而直到1972年日立公司才采用轧辊串动技术。日立公司把串辊技术用到实验室六辊轧机上,除工作辊弯曲外,还作中间辊弯曲和串动。两年后,
1 Introduction The concept of string moving from the early fifties. For the first time it was the first time that four conically shaped intermediate rollers, axially movable, were mounted on a set of twenty rolls of Sendzimir mill, followed by the development of a group-assembled chucking roll arrangement which can be hydraulically loaded Mill window. Since then, the invention has also invented a variable chuck that can be equipped with twelve rolls, six rolls and two rolls. The application of roll-to-roll has since expanded into the design of multi-roll mills. In order to use a small work roll rolling thin strip. However, work roll bending still plays a major role in controlling crown and plate shape on conventional four-roll mills, which was not used by Hitachi in 1972. Hitachi used the roller technology in a laboratory six-high rolling mill, in addition to the work roll bending, but also for the middle roll bending and stringing. Two years later,
