鞍钢1.2米四辊可逆式冷轧机是苏联五十年代制造的老设备,原更换工作辊采用套筒式方法,换一次辊需25～40分钟,不但影响作业率,而且劳动强度大,操作也不安全。由于上述原因,往往不能定时或定产地换辊,从而影响到板型和表面质量。为解决此问题,我们根据该轧机的结构,在分析国外新旧轧机快速换辊装置特点的基础上,设计出了一套比较合理的快速更换工作辊的装置(以下简称快速换辊 Anshan Iron and Steel 1.2 m four-roll reversing cold mill is the Soviet Union made in the 1950s old equipment, the original replacement work roll sleeve method, a roll for 25 to 40 minutes, not only affect the operating rate, and labor-intensive operation Not safe. Due to the above reasons, it is often not possible to change the rolls regularly or locally so that the quality of the panel and the surface is affected. In order to solve this problem, based on the structure of the mill, based on the analysis of the characteristics of the rapid roll changing device of new and old rolling mills in foreign countries, a set of reasonable device for quick changing working roll (hereinafter referred to as quick change roll
