The output of the varietal size deviation meter is connected to the fourth input of the procAn shape correction unit of FIG. 1, a block diagram of the first embodiment of the preferred device is shown; Fig. 2 is a block diagram combining the second and third versions of the device. The device according to the first embodiment comprises stands 1 and 2, respectively, with vertical 3 and horizon. 4 rolls, rolling 5, rolling direction 6, electric motors 7 and 8 devices, gauges 9 and 10 of rolling force, gauges 11 and 12 of position of pressure screws, thyristor converters 13 and 145 blocks 15 and 16 of deformation calculation of stands I and 2, respectively, with electric motors 7 and 8, gauges 9 and 10 of EFFORTS rolling, gauges 11 and 12 positions of pressure p, nts 3 thyristor converters 13 and 14 and blocks 15 and 16 for calculating the deformability of the stands form control systems on the simulators of stands 1 and 2. rolling motors 17 and 18 stands 1 and 2, respectively, tyrrytor converters 19 and 20. meters 21 and 22 rolling speeds electric motors 17 and 18, respectively, and the thyristor converters 19 and 20 and the meters 21 and 22 of the rotational frequencies of the rolling motors 17 and 18 form control systems for the rolling motors 17 and 18, respectively, meters rejected 23 vertical and horizontal 24 rolling sizes, the first speed correction block 25, the rolled shape correction block 26, the second speed correction block 27 and the first roll gap correction block 28, which is connected to the input of the pressure control system of the previous stand 1, moreover, the output is measured by the 24 deviation of the horizontal size of the rolled product connected to the input of the control system of the rolling electric motor 18 of the subsequent stand 2 through the first speed correction unit 25, the output of the first correction unit 28 The clearance is connected to the input of the control system by the pressure screw of the previous stand 1, and the input is connected to one output of the car shape correction unit 26, the other output of which is connected to the inputs of the rolling motor control systems 17 and 18 of the adjacent rolling stands 1 and 2 respectively, the first and second inputs of the rental form correction unit 26 are connected respectively to the outputs of the horizontal rental gauge 24 and the first stand correction rate unit 25. The block diagram in FIG. 2, combining the second and third versions of the device, additionally comprises a second block 29 for adjusting the roll gap, the input of which is connected to the output of the meter 23 of the vertical size of the rental, the output to the third input of the block 26 for correcting the shape of the rental and the second block 29 for adjusting the roll gap of the subsequent stand 2. The third version of the proposed device is shown in FIG. lectures In Figures 1 and 2, the following notation is adopted: L - set values, respectively, of horizontal and vertical values:; g "l set values of the speeds of the electric drives, respectively, followed by and previous stands. The device works as follows. Based on the data on deviations of the vertical and horizontal output of the | -clock and size of the rolled products coming from the respective meters 23 and 24, the block 26 for correcting the shape of the rolled product calculates such deviation values of the vertical yy and horizontal 4t) rolling sizes of the previous output ( -1) th stand, which fully compensates for the declination of LC of horizontal size at the output of the i-th stand. The calculation is made according to the formulas: 4-i ir7k-- N (..., и | ш - constant coefficients characterizing the rolling mill. For a mill equipped with rigid stands and for the i-th stand of which there is a slight deviation of the vertical size, block 26 for the correction of the form of rolling can be implemented by calculating the following formulas:, (4) Vl where,, is a constant value, and if ot, O, ubf changes, and if C 1, then at the output of (} -1) The second rolling stand has the shape of an ellipse. The second speed correction block 27 implements the following relationship: 4V -. , is a constant coefficient. The first correction block 28 of the MeKBanKO gap realizes the dependence. Where is EB, is a constant coefficient. In the second block 27 of the speed correction, it is calculated using the formula

The first speed correction block 25 realizes the 1 3b./dV dependence; where dbi / 3V is a constant coefficient The second block 29 of the inter-blade gap correction realizes the 5i-i dependence, 9b, / d5. Where Eb / E5 is a constant coefficient by acting on the roll stand of the stand. When adjusting the vertical size b by acting on the roll roll ST of the i -th stand, the horizontal size b of rolled products is known. Between the deviations of the horizontal size of rolled metal and me roll gap, there is a connection, 3, ..., (10) 45. E9 | constant coefficient
    The deviation of the horizontal size, represented by equation (10), can be eliminated by affecting the speed of the stand, since it is known that

Then the correction effect on the stand speed in order to compensate for the deviation of the horizontal size of the rolling stock caused by the change in the roll gap, in accordance with equations (10) and (11), is dfe. DS, -. (12 | 93 3b- / dV. Corrective action by equation (12) is added in the first speed correction block 25 with the value calculated by equation (8). If the magnitude of the coefficient in equation (12) is not adequate, then the horizontal size deviation cannot be fully compensated. Therefore, the first correction block 25 speed is complete It adjusts the speed of the i-th stand, for example, according to PI law on the horizontal size deviation of the car. Thus, 5 the first speed correction unit 25 performs the speed correction of the 1st stand and the regulation on the horizontal size deviation at the same time. improve the accuracy of the adjustment of the geometric dimensions.
