摘　　要：在轧制宽带钢之后轧制窄带钢的轧制次序将会导致宽度方向板厚波动,出现浪形的缺陷·为了防止这些缺陷,对国内某厂2050mm热连轧机组前5机架采用CVC工作辊,而F6、F7机架采用了平工作辊轧制·考虑到横移位置与辊缝轮廓形状之间的关系,开发了适合于平工作辊的最优横移新方式,使得在板带和工作辊的接触区形成光滑的辊缝形状,从而实现自由程序·并将最优横移新方法应用到国内某厂2050mm热连轧机的改造中,取得了满意的效果·?The strip wave flaws along the width direction will appear when narrow strip are rolled after wide one has been rolled. In order to get rid of such flaws, CVC work roll was adopted from F1 to F5 while flat roll was adopted in F6 and F7 to realize smooth profile contour curves. The relationship between shift location and roll gap figure was studied so that proper optimum shift methods were used to form smooth strip figures by shaping fine roll gap figures in the touch area between strips and work roll to achieve the SFR. Results of analyzing model calculation were applied to a production line and satisfying outcomes were obtained.
