T400工艺板在滚筒式飞剪控制中的应用

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.

Application of T400 Technology Board Worked in Rotary Flying Shear Control System

The rotary flying shear is an important part of the cold-rolling production line.Its control performances have directly impact on the cutting precision and product quality.The flying shear control always used PLC control system in the past.When the cut-point of cold-rolled strip mill appeared at the end of the cold frame the entrance,it was discussed how to apply T400 technology boards with gear common control the operation of flying shear,and the effect of three closed-loop control of the T400 technology b...
