摘　　要：介绍了西马克(SMS) 3 100 mm铝热精轧机的6次CVC plus曲线在实际使用过程中出现的实际窜辊区间小,轧制硬铝合金边部厚度小,卷材凸度偏大且不稳定,横截面出现"M"字形等板形问题。通过等效辊缝分析表明,西马克原6次CVC plus曲线的等效辊缝在距离边部900 mm处的两个小曲率半径拐点是产生板形缺陷的主要原因,为此,提出了5次CVC曲线的优化方法,所提出的方法对板形缺陷改善效果明显。Some problems appear in the use of six power CVC plus curve of Siemag（ SMS）3 100 mm aluminum hot finishing mill,i. e. small range of roll shifting,small edge thickness of rolled hard alloys,large and unstable coil crown,＂M＂shape on the cross section and so on. The analysis of SMS equivalent roll gap shows that small radius inflection points at 900 mm from two edges are the main causes for profile defects. A five power CVC curve is therefore proposed,thus greatly improving the product profile.
