摘要：针对国产高线飞剪系统剪切定位不精确、运行不稳定以及剪切速度不高等缺陷，设计了基于GE 90-30可编程逻辑控制器（PLC）的高线高精度飞剪控制系统，实现了轧线信号及处理、夹送辊操作、飞剪驱动模块、头部剪切操作、尾部剪切操作、单剪切、报警等功能。结果表明：剪切速度最大可达22 m/s，剪切精度达到误差小于10 mm，具有良好的剪切精确度和响应速度。

Abstract: Aiming at the flaws in disprecision of cutting position, instability of operation and deficiency of cutting speed, a highprecision flying shear control system based on GE 90-30 programmable logic controller (PLC) was designed. The many functions were realized, such as catching and processing signal in the highline rolling production line, pinch roll operation, flying shear driving module, forehead cutting operation, rear part cutting operation, single cutting, alarm, and so on. The practice indicates that the cutting speed can achieve 22 m/s and the error of cutting precision is smaller than 10 mm, which means this system has excellent cutting precision and outstanding speed of response.
Key words: highspeed wire rod; flying shear; programmable logic controller (PLC); control system
