    The inputs of which are connected to the outputs of the correction blocks of speed 13 and tension 17, respectively, the input of which is connected to the output of the memory block 16, whose inputs are connected respectively to the output of the mill roll rotation sensor 20 and through the temperature converter 15 in the strain relief to the meter output 14 rolled temperatures. The drawing also indicates the target speeds for the drives J and and (i-l) -ft of the N stands; and Nj, respectively; the tension of the band between the I and (} -1) cells. The device works as follows. In order to determine the interstate tension, the signals from the metal pressure sensor 9 on the rolls and the current sensor 10 measure the moment when the end of the rolled product entered the (i-1) -ro stand. When the front end of the steel is caught by the rollers | - and stands, re-measure the same parameters. Calculation of interstand tension is made according to the formula 4 liters. 1t) о Vi 0 -Jli-rp-P, L (1-00 / is the constant ratio of the current magnitude of the electr of the drive (i-1) and the cage, respectively, before and after the metal is seized pressure values in tal rolls on (1-1) th stand, respectively, before and after the metal is picked up by rolls G and stands. The temperature deviation converter 15 corresponds to the change in the strain force of the metal, and the 16p unit performs the functions of a transport block in the tension correction block 17 according to the value of the change in the deformation force and the specified value of the interstand tension T,, the magnitude of the tension correction & T, - ,, is calculated. Since the intercellular tension is determined by the ratio of the speeds of adjacent stands, the device has two tension correction channels. On one of them the signal from the output of the t7 correction block after The corresponding transformation in block 18, taking into account the magnitude of the corrective action of the speed correction unit 13, is fed to the input of the electric drive control system of the subsequent 1 and stand. Alternatively, the signal from the output of the tension-to-speed conversion conversion unit 18 is further converted in the computing unit 19 to the amount of the tension setting correction, which is fed to the comparator 21. The introduction of temperature correction and temperature correction parallel to affect the next, i and, the stands and on the interstand tension setting will allow to increase the accuracy of the geometrical dimension of the rolled stock at the output of the i - adhesives.
