摘　　要：某钢企1780热连轧生产线投产以后,R2粗轧主电机止推轴承经常发生异常磨损事故。此后在现场做了一系列的试验,并在此基础上分析了现有主电机止推轴承的承载能力和造成该主电机止推轴承损坏的可能外部原因,得出了该止推轴承承载能力不足是产生事故的根本原因,并依此为依据进行改造,问题得到了解决。After commissioning of a 1 780 mm HSM,the abnormal wearing of the main drive thrust bearing in the R2 roughing mill happened frequently.To resolve this problem,some tests are made and the motor thrust bearing＇s capacity is anlysised.It concluded that the reason for the bearing damage is the lack of bearing＇s capacity.The problem is solved by reselection the bearings based on this conclusion.
