介绍一种超薄带精密轧机的计算机控制系统改造。超薄带精密轧机用于轧制０．０１ｍｍ～０．５ｍｍ的超薄带材，其辊形调节系统是影响带材板形的关键部分。原系统响应慢，可靠性差，难以满足精轧要求。现对该轧机进行改造，采用计算机，将ＰＣＭ（ＰｕｌｓｅｃｏｄｅＭｏｄｕｌａｔｉｏｎ－脉冲码调制）控制与二次型性能指标最优化控制相结合的控制方法用于轧机的的全面管理与控制，不仅大大提高系统精度与运行可靠性，而且实现调整与控制自动化。目前已投入正常运行。
Introduce a kind of ultrathin strip precision rolling mill computer control system reformation. Ultra-thin strip precision rolling mill for rolling 0.01mm ~ 0.5mm ultra-thin strip, the roll adjustment system is a key part of the strip shape. The original system slow response, poor reliability, it is difficult to meet the requirements of finishing. Now the transformation of the mill, the use of computer, PCM (PulsecodeModulation-pulse code modulation) control and secondary performance index optimization control method for the comprehensive management and control of rolling mill, not only greatly improve system accuracy and Operating reliability, but also to adjust and control automation. Has been put into normal operation.
