Abstract

PURPOSE:To high accurately control the interstand tension, by giving a time delay equivalent to the traveling time of the material from the thermometer to the stand to the temperature of the material measured on the feed-in side of the rolling mill, and by operating the temperature compensation for the stand and the variation of the rolling torque on the basis of above time-delayed material temperature. CONSTITUTION:The material temperature on the feed-in side of the rolling mill is inputted to the delay unit 3 which then gives a time delay to the material temperature by the traveling time between the thermometer and the i-th stand. This time-delayed material temperature is inputted to the material temperature arithmetic unit 4 which then operates the material temperature; and the temperature compensation arithmetic unit 5 operates the variation of the rolling torque of the i-th stand owing to the temperature variation. The output of the temperature compensation arithmetic unit 5 and the output of the rolling torque arithmetic unit 7 are added, and the temperature-compensated rolling torque is operated and is compared with the rolling torque under the tensionless condition to be memorized in the reference torque memory unit 8. Hereby, the rolling torque variation corresponding to the variation of the interstand tension is obtained. This value is inputted to the reference speed correction unit 9 for correcting the reference speed of the motor, and the motor speed of the i-th stand is adjusted through the speed control unit 10, and the tension is controlled to the specified value.
