滚筒式飞剪是冷连轧生产线上的重要组成部分,其控制性能直接影响着剪切精度与产品质量,而以往飞剪控制多采用PLC控制系统。讨论了当冷轧带钢的剪切点在冷连轧机的末机架入口出现后,如何采用工艺板T400结合传动装置共同控制飞剪的运行,并验证阐述了应用T400工艺板的三闭环控制。结果证明飞剪响应快速灵敏,带钢剪切断面光滑。
Roller flying shear is an important part of the cold tandem rolling production line, its control performance directly affects the cutting accuracy and product quality, and the past flying shear control more PLC control system. It is discussed how to control the operation of flying shear with the technology board T400 combined with the transmission when the cold rolling strip’s cutting point appears at the end of the tandem cold rolling mill and verify the application of the three closed-loop control of the T400 technology board . The results show that the flying shear response is fast and sensitive, the strip shear section is smooth.
