<p>PURPOSE:To improve the product yield and the working efficiency by detecting a width on the mill outlet side, calculating a deviation from a set width, and adjusting a work roll position based on the deviation. CONSTITUTION:A width detector 6, a work roll moving amount computing element 5, and a movement adjuster 4 are installed on the outlet side of work rolls 1, 2 having a crown. At the time that a width of a rolled stock 3 is detected by the detector 6, a detection signal is sent to a width deviation detec tor 8 and a deviation between the detected width and a criterion width set by a criterion width setter 7 is calculated. Then, a position or the rolls 1, 2 are adjusted based on the deviation to control a stock width through the element 5 and a movement adjuster 4. By such method, the product yield and the work ing efficiency are improved and interactions between a thickness control and a width control are eliminated because of elimination of the trim work for width control.</p> |
