Abstract：The statistics show that, the shape defects of steel coils on cold rolling recoiling line, alloy plate and sheet for home electrical appliances accounted for the highest proportion, followed by the general board and Foxconn plate, the proportion of galvanized plate is the lowest. The proportion of shape defects is higher after the cut edge. The sensitive area of the shape defects:width is 1 201-1 250 mm and thickness is 0.7-0.8 mm. Analysis suggests that, the main reason of the shape defects is poor production unit rectifying effect; disk shearing edge strip serpentine waves; poor stability of roll system. Through the study of the transformation of production line equipment the shape defects of steel coils can be reduced.
