<p>PURPOSE:To apply the tension controlling of many kinds of materials by fuzzily estimating every kind of controlling factor based on the information of the material to be rolled with the tension controlling device. CONSTITUTION:In the tension controlling device providing a tension arithmetic means 4 operating the tension of the material to be rolled between stands based on the rolling load and the rolling torque of each stand, a proportional integration element researching the correcting amount of the rotation velocity of the stand driving motor 20 by operating the proportional integration based on the deviation of the operated tension and the target tension, and a velocity controlling means controlling the rotation velocity of the motor based on the rotation velocity correcting amount, an estimating means which fuzzily estimates the controlling factor of these proportional integration elements based on the information of the material to be rolled is provided, and the controlling factor is set with this under the estimated value. In such a way, the high precise tension controlling can suitably executed for many kinds of materials.</p> |
