热轧层流辊道电动机状态监测系统的设计与应用

Design and application of motor condition monitoring system for hot rolling laminar roller table

热轧层流辊道电动机是整个热轧生产线的关键设备之一，能否正常运行直接影响产品的质量、产量。通过分析层流辊道电动机运行状况，建立一套电动机状态监测系统，对每台电动机电流进行实时监测与报警预警。运行实践表明，该系统能够降低辊道事故的发生率，保证产品质量，保障轧线的稳定运行。

Hot rolling laminar roller motor is one of the key equipments in the whole hot rolling production line. The normal operation of hot rolling laminar roller motor directly affects the quality of products. This paper analyzes the running status of the laminar roller motor. A motor condition monitoring system is established to monitor and alarm the current of each motor in real time. The operation practice shows that the system can reduce the occurrence rate of roller accident, ensure product quality and ensure the stable operation of rolling line.
