Abstract：Equally- spaced longitudinal stripes introduced in hot rolling process couldn’t be completely eliminated after pickling，cold rolling and continuous annealing，which seriously affect the quality of finished product. Defect evolution research during the whole process and technological experiment have been carried out，which confirmed that the translations of grinding spiral lines，closely related to the roll grinding process and CVC roll profile curvature，from the finishing work roll surface in last pass to the steel strip surface，was the main cause. Grinding spiral lines on roll surface and the resulting equally- spaced longitudinal strips in hot- rolled sheet surface were caused by the mismatch of grinding wheel surface and the roll surface curve，and could be completely eliminated by optimizing CVC profile of finishing work roll and roll grinding parameters.
