<p>Method of equalizing the thickness of a rolled sheet in a rolling mill for rolling a steel strip. In accordance with the method, a draft-positioning control unit and/or a tension-adjusting unit in a rolling mill meysures, in order to memorize, the variations in the thickness of a steel band at the entrance portion of the rolling mill, by conducting sampling at a given interval ((Alpha)t) which is less than 1/5 the period of the response cut-off frequency in each unit, and then computes control signals from two or more values among the memorized values at the interval (Alpha)t, the calculated value being utilized for draft-positioning control and/or tension adjustment. </p> |
