由于改造了我们工厂钢管轧机的一些部件和机构,大大缩短了机组停工时间和改善了检修条件。在穿轧机的前台上,由于轧制时坯料经常冲击,进料台的前端常常损坏而报废。改造前的进料台是焊接的槽形框架,槽壁用钢盖板1(图1.a)保护,盖板用埋头螺钉固定。螺钉经常断裂,从而破坏了长行程气动 Due to the modification of some of the components and mechanisms of our mill’s steel tube mills, unit downtime was significantly reduced and maintenance conditions were improved. On the front of the mill, due to the frequent impact of the blank during rolling, the front end of the feed table is often damaged and scrapped. The pre-retrofit feeder table is a welded, trough-shaped frame, protected by a steel cover 1 (Fig. 1a), and the cover secured by a countersunk-head screw. Screws often rupture, destroying long stroke aerodynamics
