摘　　要：针对1422 mm热轧生产线F1轧机更换工作辊窗口或牌坊窗口底部衬板后出现的轧机正反转刚度差问题,通过测试轧机垂直系的摇摆板、换辊小车、牌坊窗口等,确定牌坊窗口底板过度腐蚀是主因,在采取改进措施后,该轧机牌坊正反转刚度差稳定在5%以下。In order to solve the problem of the rigidity difference between forward and reverse rolling after changing the work roll window or the bottom liner of the housing window of F1 in the 1422 mm hot strip rolling line,tests are carried out to check the wobble plate,roller changing car and housing window of the vertical system of the mill,and confirmed that the main reason is over-corrosion of the bed plate of housing window.After taking improvement measures,the rigidity difference of forward and reverse rolling of the mill housing is steadily below 5%.
