A simulation model for predicting the shapes of cold-rolled strips in 20-high Sendzimir mills was developed, and its predicting accuracy was assessed experimentally. By this model, improvement of quarter buckles was shown difficult merely by conventional shape control actuators, i.e., lateral shifts and taper profiles of first intermediate rolls, roll crowns of work rolls and second intermediate rolls, and crown adjustment of back-up rolls. It was shown that quarter buckles could be effectively corrected by giving a concave profile partially to the first intermediate rolls.
