<p>PURPOSE: To provide a method and a device of shape control in a cold-rolling mill by which defects in shape of local elongation and compound shape are suppressed and shape control is carried out with high accuracy. CONSTITUTION: A plurality of air nozzles 95 are disposed along the width direction of a material 2 to be rolled on the outlet side of the cold-rolling mill 15 and air is jetted from the air nozzles 95 onto the material 2 to be rolled. The manipulated variable of the air jetted from a plurality of the air nozzles 95 is determined by using shape absolute value deviation and shape space deviation which are determined from the target shape and a detected shape with a shape controlling device 5. The air quantity jetted from a plurality of the air nozzles 95 is adjusted on the basis of the manipulated variable of the air with an air adjusting device 84.</p> |
