摘要： 以典型的轧辊横移变凸度辊型,如基本CVC辊型曲线、优化设计的CVC辊型曲线及SMARTCrown辊型曲线为研究对象,从辊型曲线设计、轧制过程中轧辊所受轴向力及无载辊缝凸度等方面进行比较分析.结果表明:当板宽位于800~1 600 mm区间时,采用优化设计得到的CVC辊型曲线会获得较小的轴向力;相对于CVC轧辊而言,SMART Crown无载辊缝在带钢两肋波浪敏感区要大一些,故在控制带钢的双边浪缺陷上具有一定的优越性.

Abstract: Some typical roll shapes available to vary roll gap through roll shifting in rolling process were analyzed comparatively, such as basic CVC roll, optimal CVC roll and SMART Crown roll in view of the shape design, axial load acting on the roll and no-load roll gap. The results showed that when using the optimal CVC roll shape, the axial force is smaller if the strip width is in the range from 800 to 1600 mm. On the SMART Crown rolls, the no-load roll gap in both flank zones is bigger than CVC roll, which is sensitive to shape wave, so, the SMART Crown roll has superiority in controlling strip shape wave.
