Abstract
PURPOSE: To perform constant-tension control of high precision by detecting rolling torque and rolling force by each of several stands, calculating the tension control amount by use of the difference amount of the difference of the ratio of torque and rolling force of the neighboring stands, and the difference of the torque arm, and adjusting the tension by the foregoing.
CONSTITUTION: The rolling material is fed into the first rolling stand 1, and before it is fed into the second rolling stand, its rolling torque and rolling force at the stand 1 are detected, the ratio of both of them is operated with the divider 15, and it is stored in the memroy 16a. Subsequently, after the one short relay 17a has been released, when the rolling material is fed into the stand 2, the torque arm equivalent amount (G2/P2)0 of the stand 2 is operated from the output of the memory 16a and the output of the divider 19, and it is stored in the memory 16b. Before the rolling material is fed into the stand 3, by taking the difference of the output of the divider 15 of the stand 1, and the divider 15 of the stand 2, and also deriving the difference of the output of the memories 16a and 16b, the speed of the stand 1 is controlled so that the difference of both the differences mentioned hereinabove can be zero.
