<p><P>PROBLEM TO BE SOLVED: To provide a method for consistently passing a rolled plate in a longitudinal continuous annealing equipment without causing any heat buckle or walk even when the shape control function of a rolling mill is not sufficient, or even when an abrupt shape change is present, and the shape correction is not in time. <P>SOLUTION: In a shape control method of a steel plate in a cold rolling mill for feeding a plate in a longitudinal continuous annealing equipment, the shape distribution of a rolled material 2 in the plate width direction is detected by a shape detector 10, the weighting function is multiplied by the output value of the detected shape distribution, and the weighted bending moment is calculated from the value. By controlling the difference between the right and left gaps of a rolling roll so that the calculated weighted bending moment becomes constant, the shape of the steel plate is controlled, and the walk in passing the steel plate in the longitudinal continuous annealing equipment is reduced thereby. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
