换辊作业是轧钢生产过程中经常进行的一项工作。目前,国内的一些轧钢生产线,大都还没有实行自动化换辊,而是采用行车吊着 C 型钩,借助人工牵引来换辊(图1)。行车吊钩钩住 C 型钩的钢丝绳套,C 型钩底梁的套筒套住轧辊的辊头,为了掌握轧辊的装卸方向,避免 C 型钩和轧辊摇晃,必须安排人员扶着 C 型钩。为了使 C 型钩套住轧辊脱离或连接万向轴的端头,并顺利地从轧机牌坊中进出,需要行车吊着 C 型钩常起常落。如果吊钩下降过多,C 型钩的底梁又被搁 Roll change operations are a frequent part of the rolling process. At present, some domestic rolling production lines, most have not yet implemented automated roll change, but the use of traffic hanging C-hook, with manual traction to change the roll (Figure 1). Hooks hooked C-hook wire rope sets, C-beam hook sleeve sits the roller head, in order to grasp the roll loading and unloading direction, to avoid C-type hook and roller shaking, we must arrange for staff to hold the C-type hook . In order to make the C-shaped hook sleeve live roll off or connect the end of the universal shaft, and smooth access from the mill arch, you need to drive a C-hook hanging from the often. If the hook descends too much, the C-hook’s bottom beam is put back
