Development and Application of the Model Controlling Strip Tailing-out on the 2 050 mm Hot Rolling Line
Pages: 69

Journal: Bao-Steel Technology

Keyword:  轧制抛钢控制模型;
Abstract: 尾部抛钢是一个快速复杂的过程,从带钢尾部众多影响因素中,找到了改善方法,分析出依轧机本身轧制力偏差自动调平的可行性,并开发了尾部轧辊自动调平功能及相关模型.控制模型从研究两侧轧制力偏差入手,出发点是根据在精轧机抛钢的一瞬间,判断带钢的"游动"趋向,对轧辊辊缝进行自动调平处理.2 050 mm热轧产线上开发及运用依轧制力自动调平取得成功,在<2.0 mm薄板产量大幅增加情况下,轧破事故辊发生量减少了50%.
