摘要
258PQF机组连轧前台支撑辊调整装置设计存在一定的缺陷,通过对支撑辊调整装置的故障进行分析总结,查找设备故障原因,根据实际情况提出更合理的改进方案并实施,通过对调整装置的改进,设备故障率显著降低,提高了支撑辊装置设备运行的稳定性,支撑辊的高度定位更精确,节约了设备的维护及备件成本。
Aiming at the design defect existing at the back-up roll adjustment system at 258 PQF front platform, revamp was executed on mechanical drive system, hydraulic control system and electric control system at Tianjin Pipe Corporation. Equipment fault rate was obviously lowered and the positioning of back-up roll height more accurate. The running stability of back-up roll was improved and production cost saved.
