摘　　要：为了提高连轧锥形工作辊轴向窜动控制精度,对材料加工时发生横向流动的过程建立有限元模型,并构建了机架轧后屈服模型,并将模型置于现场环境中开展验证研究。研究结果表明:受到轧后屈服作用时,处于边降区(15~115)mm之间的断面误差可以控制到3μm范围内,与带钢边部的最大偏差在(0~15)mm之间。在机架间和轧制区内都出现了横向流动的情况,导致锥形辊发生了边降调控性能下降。随着窜辊量增大后,第一、二机架都出现功效下降的结果,第三机架则持续增大至最高功效。下游机架窜辊位都位于上游机架控制特征点范围内。这里调控方式形成了显著边部效果,可以观察到内部偏差。该研究对保证板材的轧制质量具有很好的实际指导价值。In order to improve the control accuracy of axial channeling of conical working roller in continuous rolling,a finite element model was established for the process of transverse flow during material processing,and a post-rolling yield model was established,which was verified and studied in the field environment.The results show that the error of the section between 15mm and 115mm in the edge drop zone can be controlled to 3μm,and the maximum deviation from the strip edge is between 0mm and15mm.The lateral flow occurred in both the frame and the rolling area,which resulted in the decline of the edge drop control performance of the conical roll.With the increase of roll channeling,the efficacy of the first and second racks decreased,and the third rack continued to increase to the highest efficacy.The downstream frame roll shifting positions are located in the range of the upstream frame control feature points.The control method produces significant edge effect and internal deviation can be observed.The research has a good practical guiding value to ensure the rolling quality of sheet metal.
