双机架平整机自动化控制系统

Automation Control System of Two-stand Temper Mill

阐述了双机架平整机的用途,并对其控制模式进行了详尽介绍。双机架平整机控制分为一轧一平及单平整2种工作方式。给出自动化控制系统控制方案和仪表配置方案。该控制系统内包含直接张力闭环、间接张力闭环、前馈AGC、反馈AGC等具体控制方法。给出了通常情况下延伸率设定的依据。实践证明,采用本控制方式的双机架平整机可以很好地满足镀锡板带材成品的板形要求,达到了良好的控制目的。

The utility and control model of the two-stand temper mill including control scheme and hardware configuration of the automation control system were introduced.The whole system adopted one-mill one-temper mill or single temper mill method.The control scheme of automatic system and instrument configuration stcheme were given.It also had a discussion about basis of elongation setting in normal conditions.The system had direct tension close loop control,indirect tension close loop control,feed-forward AGC and feed-backward AGC control schemes etc.The foundtions of elangation rate setting usually were given.The final production can fully meet the requirement of finishedproduction.
