摘　　要：总结分析了冷成形带钢卷取折痕的产生规律和影响因素,通过现场试验确定卷取折痕的主要影响因素为带头卷入状态,采取在卷取前增加三辊矫直设备来改变带钢进入卷取的翘曲状态,达到了有效改善卷取折痕的目的。This paper summarizes and analyzes the generation rules and influencing factors of fold marks in cold formed strip steel coils.Through on-site experiments,it is determined that the main influencing factor of fold marks in coils is the winding state of the leading end.By adding a three roll straightening equipment before coiling,the warping state of the strip steel entering the coiling process is changed,effectively improving the coiling fold marks.
