摘　　要：新钢棒二产线在生产中面临250辊箱油膜轴承频繁烧损问题,常导致生产中断,使维修成本增加。针对此,深入分析新钢棒二线辊箱烧损的末端原因,并围绕规范工艺操作以减小轧机负荷、优化装配方法来提高装配精度、净化油品质量以减小设备磨损以及改进轴承结构以提升承载能力这些技术措施展开了详细的QC攻关研究。The new steel rod secondary production line is facing the problem of frequent burning of 250 roller box oil film bearings in production,which often leads to production interruption and increases maintenance costs.In response to this,a thorough analysis was conducted on the end causes of the burnout of the new steel bar's second-line roller box,and standardizing process operations to reduce rolling mill load,optimizing assembly methods to improve assembly accuracy,purifying oil quality to reduce equipment wear,and improving bearing structure to enhance load-bearing capacity are focused on.Detailed QC research was carried out around these technical measures.
