1、引言异步轧制是指两工作辊的轧制速度不对称的一种新的轧制方法。现已用于S异步轧制(或称法轧制)、平整生产和单机连轧。它比一般的同步轧制(或称对称轧制,即两工作辊的轧制速度相同的轧制方法)有可能成倍地降低轧制压力和转矩,提高带材的厚度精度,以及有可能简化自动控制系统。异步轧制是近十年左右才被重视并进一步发展起来的,但不论是从工艺、设备,还是从理论上研究得很不够。因而从理论上搞清楚异步轧制的特点,从工艺设备上使这种轧制方法 1, Introduction Asynchronous rolling refers to a new rolling method of asymmetric rolling speed of two work rolls. Is now used for S asynchronous rolling (or called rolling), flat production and stand-alone rolling. It is possible to reduce the rolling pressure and torque exponentially and to increase the thickness accuracy of the strip more than conventional synchronous rolling (or symmetrical rolling, that is, rolling with the same speed of two work rolls) May simplify the automatic control system. Asynchronous rolling is valued and further developed in the last ten years or so, but it has not been enough in terms of technology, equipment or theory. Thus theoretically clear the characteristics of asynchronous rolling, from the process equipment to make this rolling method
