一、前言准确停车是可逆式冷轧机生产过程中的关键环节之一。苏联原设计的机电式准确停车装置,技术不过关,根本不能使用。所以,轧机的减速和停车等动作全靠手动操纵,即使工人在生产中精神高度集中,也不能够避免出现剩余板头过长的现象,浪费了原材料,又降低了成材率。更严重的是,如果生产中稍一疏忽,板头就有进入轧辊的危险,势必造成重大的设备事故。为此,钢板轧制过程中,工人的精神 I. Preface Accurate parking is one of the key links in the production of reversible cold rolling mills. The original design of the Soviet Union electromechanical accurate parking device, but the technology off, simply can not be used. Therefore, the rolling mill deceleration and parking and other actions rely entirely on manual manipulation, even if the workers in the production of a high degree of concentration, it can not avoid the phenomenon of excess plate head is too long, waste of raw materials, but also reduce the yield. More seriously, if there is a slight oversight in production, there is a danger that the head will enter the roll, which will inevitably cause a major equipment accident. To this end, the plate rolling process, the spirit of the workers
