【摘要】 在不干扰冷轧AGC控制系统工作状态的情况下,研究了冷连轧焊缝过机架时的辊缝进行自适应控制的方法,建立焊缝过机架时各个机架的辊缝调节自适应模型以及单个机架的辊缝自适应调节模型.现场使用效果表明该模型改进了非稳定状态下轧制过程的稳定性和控制精度,减小了各机架在带头通过时出口厚度的波动,从而减少产品的超差长度,提高成材率.更多还原

【Abstract】 The self-adaptive control was investigated in case that a weld line of tandem cold rolled strip work-piece is passing through a roll gap under conditions that there is no disturbance to the AGC system.The adaptive adjusting models were therefore developed for each and every roll gap on different mill stands.The application results of these models showed that the stability and control accuracy are both improved in the unsteady rolling state with the thickness fluctuation of strip head decreased at the exit of all stands,thus shortening the over tolerance length of products and raising the rate of finished products.更多还原
