摘　　要：介绍福建泉州闽光钢铁有限责任公司轧钢厂高棒精轧机辊箱及惰轴的结构及常见故障。辊箱常见故障有油膜轴承烧损、偏心套拨叉断裂、眼镜板变形、铜螺母断裂等;惰轴常见故障有油膜轴承烧损。通过深入现场了解辊箱及惰轴的运行情况,深入分析故障原因,并通过科学理论分析计算,提出降低精轧机辊箱及惰轴故障率的改善措施。经改进后,辊箱及惰轴的使用寿命大大提高,为高棒生产线的稳定生产保驾护航。Introduce the structure and common faults of the roll box and idler shaft of the high bar precision rolling mill at Fujian Quanzhou Mingguang Steel Co.,Ltd.Rolling Plant.Common faults in the roller box include:burnt oil film bearings,broken eccentric sleeve forks,deformed eyeglass plates,and broken copper nuts.Common faults of the idler shaft:oil film bearing burnt out.Through in-depth on-site understanding of the operation of the roller box and idler shaft,a fault cause analysis and scientific theoretical analysis calculation are conducted to propose improvement measures to reduce the failure rate of the precision rolling mill roller box and idler shaft,improve the service life of the roller box and idler shaft,and provide support for the stable production of the high bar production line.
