硅钢冷轧过程中遇到孔洞缺陷经常断带，为了保证轧制状态平稳，经过分析孔洞缺陷导致断带的原因，结合森吉米尔轧机先进的板形控制技术，提出板形目标曲线动态设定控制方法，并成功应用到20辊森吉米尔轧机上。试验结果表明，板形目标曲线动态设定控制方法对减少缺陷断带，稳定轧制状态具有非常显著的效果。
It is common that during the rolling process,there would be broken belt when hole defect appears.In or-der to ensure a smooth rolling state,the causes of defects broken belt holes was analyzed,combined with advanced Sendzimir mill flatness control technology,proposed plate-shaped curve dynamically and set the target control meth-ods,and successfully applied to the 20-roll rolling mills.Experimental results show that the plate-shaped curve of the dynamic target set-off control method has a very significant effect on reducing defects and keep a stable rolling state.
