Abstract
PURPOSE: To control the thickness, crown and shape, in order to improve the quality of a material to be rolled, by controlling the rolling reduction and the circumferential speed ratio of rolling rolls.
CONSTITUTION: The sheet thickness and crown and shape are computed from the rolling and load measured by a load cell 8 installed in a rolling mill 7; the roll gap and the rolls' circumferential speed ratio the most suitable for absorbing the computed thickness deviation, crown deviation and shape deviation, are computed; thus obtained roll gap and the circumferential speed ratio are inputted as the control reference to a rolling reduction controller 5 and a speed controller 2; these controllers 5, 2 then control the thickness, crown and shape. The results of thus controlled thickness, crown and shape, are measured by a thickness gauge 9, a crown meter 10 and a shape meter 11 installed on the run-out side of the rolling mill; these measurements are sent as the feedback to a control computer 1 in order to suitably correct a model stored in the computer correspondingly to the control error.
