Abstract

PURPOSE:To maintain the interstand tension constant, by forecasting the average deformation resistance of the material to be rolled in each stand, and by controlling the driving speed of each stand so as to make the ratio constant between said average deformation resistance and the rolling torque of each stand. CONSTITUTION:The material is rolled by the stands (i) and (i+1) in this order after passing the thermometer 2. The temperature detected by the thermometer 2 is sent to the average deformation resistance arithmetic unit 4 through the delay device 3; the arithmetic unit 4 calculated the material temperature theta1 of the stand (i) and operates the average deformation resistance Kmi. The arithmetic unit 6 calculates the rolling torque Gi from the load of the driving motor 5. The arithmetic unit 7 calculates the ratio GiM/KmiM from the rolling torque GiM of the stand (i) under the tensionless condition and the average deformation resistance KmiM; this ratio is stored in the memory device 8. The formula I is calculated by the multiplier 10, and the formula II is obtained for the rolling torque corresponding to the tension free from the influence of the fluctuation of the material temperature. The reference speed correction unit 11 calculates the reference speed correction value DELTANi from the formula III, and corrects the rotational speed of the stand (i) by the reference speed correction value DELTANi through the speed controller 12 in order to control the tension between the stands (i) and (i+1).
