摘　　要：以热轧带钢产线飞剪前热金属检测器为研究对象,针对可能导致生产信号异常的不同原因进行了分析,提出了以异常报警、保护联锁相结合的一套简单可靠的信号稳定性综合提升方案,并成功应用于某钢厂2条热连轧生产线。生产实践表明:程序运行稳定,现场使用效果良好,有效解决了现场水汽影响、传感器及线路故障等各种异常情况下飞剪剪切不稳定的问题。Taking the hot metal detector before the flying shear as the research object, which used in the hot rolled strip production line, the reasons that may lead to abnormal production signals were analyzed, and a set of simple and reliable signal stabilization combined with abnormal alarm and protection interlock was proposed. The comprehensive improvement plan had been successfully applied to two hot tandem rolling production lines of a plant. The practice production show that the program runs stably and the on-site use effect is good.
