    The invention relates to rolling production and can be used in the production of strips on sheet mills and calenders.  The closest to the proposed technical essence and the achieved result is a method of controlling the multi-roll pressure in a roller set with continuous and composite rolls, which includes adjusting the profile of the roll roll gap by changing the external image of the barrel of the composite roll by changing the pressure of the atomic ashes relative to the barrel length of the composite roll relative to the total hydrostatic pressure in one of the longitudinal chambers, mainly from the side of the multi-roll pressure, the internal th cavity composite roll CO- disadvantage of this method is that when controlling the roll pressure along the length of the roller sets, ie,.  the roll gap profile, the control is carried out by increasing the pressure in the atomic zones relative to the hydrostatic pressure in the longitudinal chamber of the composite roll, while changing: the distribution of the roll bulk pressure as well as changing its total level. There is a need to vary the pressure to the required one, set in accordance with the value of the total multi-roll pressure.  This regulation is implemented by increasing the pressure in the longitudinal chambers and in the autonomous zones. .  Such pressure control at specified locations is energy intensive and expensive, and, moreover, high pressure control is less accurate than pressure control with a lower absolute value, such as atmospheric pressure.   A composite mill roll is known, containing a carrier axle and a bandage mounted on it with a guaranteed clearance, in the inner cavity of which two longitudinal chambers are connected with a source of working fluid, and autonomous pressure regulators in the form of plungers placed in carrier bores are installed along the carrier axis axis and supported on the inner surface of the tl3 band.  However, this roll can be used only in those proking methods, in which the regulation of the multi-roll pressure is carried out by increasing the pressure levels from the initial one in the longitudinal chambers and independent regulators.  The purpose of the invention is to improve the management efficiency.  This goal is achieved in that according to the method of controlling the inter-roll pressure in the roller set, with continuous and composite rolls, including adjusting the profile of the inter-roll gap by changing the outer forming drum of the composite roller by varying the pressure in the autonomous zones along its length relative to the total hydraulic static pressure in one of the longitudinal chambers, mainly from the side of application of the inter-roll pressure, the internal cavity of the compound roll, the inter-roll pressure is adjustable.  They are cast by reducing the absolute pressure values in the autonomous zones relative to the total hydrostatic pressure in the longitudinal chamber, oriented in the direction of the application of the multi-roll pressure.   The pressure reduction in the autonomous zones is determined by means of the connection to the container under atmospheric pressure.  The goal is achieved.  also by the fact that in a roll containing a carrier axle and a bandage mounted on it with a guaranteed clearance, in the internal cavity of which two longitudinal chambers are made, connected to a source of working fluid, autonomous pressure regulators are installed in the form of plungers located in The bores of the bearing axis and supported on the inner surface of the bandage, the plunger of the autonomous pressure regulators are hollowed out, and the cavity of each plunger is equipped with a spring, each regulator being associated with a container under the atmosphere sphere pressure.  In the longitudinal chamber oriented in the direction of application of the multi-roll pressure, no less than Tpgx of autonomous pressure regulators are made — two in Koitsi parts, and one in the center of the chamber, o In FIG.  Figure 1 shows roll pairs for implementation.  propose a new method; in fig; 2 - graphical dependence of autonomous, zones on the interfacial pressure; in fig.  3 - distribution of the multi-roll pressure along the length of the roll barrel; in fig.  4 shows section A-A in FIG.  one ; in fig.  5 is a section BB in FIG.  one; in fig. 6 - autonomous zone between rolling pressure, partial section; in fig.  7 is a diagram of the connection of the longitudinal chamber of the roll with the external container.  014 The proposed method is based on the creation of an initial uniform rolling pressure with a subsequent decrease in its autonomous zones along the length of the roll barrel, so that the forces acting in these areas are reduced compared to the previously existing uniform effort, thereby ensuring pressure.  It is within the scope of the invention to maintain a pressure level in the autonomous zones exceeding the atmospheric pressure and / or maintaining a vacuum in them.   In a preferred form of implementation of the method, it is envisaged to maintain the pressure in the autonomous zones, equal to the atmospheric pressure, when the separated zones in the longitudinal chamber are connected to the atmosphere or sump.  The proposed method is implemented; a set of rolls, of which the upper 1 roll is solid, and the lower 2 is made composite and contains a carrying axis -3 with a bandage 4 mounted on it with a guaranteed clearance.  “In the internal cavity of the roll 2 in the gap between the axis 3 and the band 4, two longitudinal chambers 5 and 6 are connected, connected to the source 7 of the working fluid.  Along the carrier axis 3, there are machined bores 8, in which autonomous pressure regulators are placed, made in the form of polk plungers 9 with spring 10.  The longitudinal chamber 5 with the help of the pump 11 through the pipe 12 fills the working fluid, setting the hydraulic pressure, which acts uniformly on the inside of the bandage from the side of the gap between the rollers and creates working inter-roll pressure.  On the other side, the working fluid rests on axis 3, which is bent under the action of this load, t. e.  perceives the corresponding counter forces required to create the inter-roll pressure, and the axis does not come into contact with the bandage.  The pressure acting on the inner surface of the bag in the longitudinal chamber 5 is forcibly equalized in length.  During the operation of the roller pair, during the processing of the material in the inter-roll gap, it is necessary to adjust the pressure at specific points along the length of the roll.  To do this, the autonomous zones 13, which are hydraulically isolated from the longitudinal chamber 5, are inserted through the plungers 9.  The end surface of the plungers, adjacent to the band, is made with the same radius of curvature and fits tightly to it, and on the opposite side of the plungers are placed in cylindrical sprouts 14 of the bearing axis 3.  The plungers 9 are under the action of springs 10, which are supported on the bottoms of the bores, while the plungers are provided with seals 15.  The bores 14 are connected to the source 7 by means of the channels 16, valves 17 and pipes 18, each having a valve 19 which can optionally open or close the channel 16. When the bandage rotates along arrow 20, it slides along the ends. plungers 9 The longitudinal chamber 5 is filled with a working fluid that forms a film on the inner surface of the band. . On the plunger edge 21 facing in the direction of the arrow 20, a portion of the working fluid is removed, so that in zones 13 there is an accumulation of fluid.  If the valves 17 are closed, the pressure in the autonomous zones 13 rises and practically corresponds to the pressure in the chamber 5.  When the pressure in zones 13 reaches the value of chamber 5, the influence of zones 13 does not affect the inter-roll pressure.  When one of the valves 17 is opened, the working fluid that enters one of the zones 13 can flow freely to the source 7, and no pressure increase occurs in the zones 13.  When one of the zones 13 is taken from the area of uniform pressure given by the working fluid in the longitudinal chamber 5, the pressure is released at this point and the corresponding effect on the distribution of the inter-roll pressure occurs.  The zones 13 in the longitudinal chamber 5 shown in FIG.  1 are advantageously used in a form of constructive design.  In addition, the reduced pressure zones 13 can be implemented in the opposite longitudinal chamber 6.  These zones can be used, instead of in conjunction with the zones located in the longitudinal chamber 5.  In order to have an effect on the inter-roll pressure, three plungers 9 are more flexible101, which can be controlled separately and allow varying pressure relief at a given location.  The valve 17 connects the channel 16 with the return pipe 18.  The opposing valve connects the supply pipe to the return pipe 22.  Thus, by choice, pressure can be released in both plungers or in all three times.  The valves 17 are electromagnetic valves that are easily accessible by means of a recess 23 for accommodating an electrical connection.  .  In the described. Forms of execution can occur only stepwise, stepwise effects on the inter-roll pressure.  Zones 13 are either locked or connected to source 7, therefore either constant pressure exists or it is absent.  However, an embodiment is possible that allows continuous variation by the effect of the individual zones 13 on the inter-roll pressure.  Typically, the working fluid is pumped through pipe 12 only into the longitudinal chambers 5 facing the gap between the rollers.  Through the longitudinal. the compaction 24, the working fluid can penetrate into the longitudinal chamber 8, from where it is returned back to the source 7.  In the embodiment of FIG.  1, an overflow pipe 25 is provided between chambers 5 and 6, which has a differential pressure valve 26.  Consequently, the required fraction of the pressure fluid of the chamber 5 continuously flows into and out of the longitudinal chamber 6.  through the tube through the pressure regulating valve 27 to the source 7.  The longitudinal chamber 6 is practically left without pressure.  It creates a certain pressure, which is lower by a predetermined amount of valve installation than the pressure in the longitudinal chamber 5.  The inter-roll pressure is now determined not by the absolute pressure in the longitudinal chamber 5, but by the pressure difference between the longitudinal chambers 5 and 6. Uniform inter-roll pressure can be obtained at low pressure levels, t. e. at low pressures in both pro- longitudinal chambers 5 and 6, as well as at high pressure levels, t. e.  at high pressures and longitudinal chambers.  Under the same, uniform conditions over 711 the length of the longitudinal chambers 5 and 6, the pressure level is not. manifests itself externally.  FIG.  7 is a schematic diagram of the control of three zones 13 arranged circumferentially in the longitudinal chamber 5.  In the position "all three zones 13 are locked and practically do not show themselves.  In position 5 of the valves 19, both outer zones 13 are deprived of pressure, while the middle zone 13 is locked.  The position in all three zones 13 is deprived of pressure and, in the wide area associated with them, reduces the forces applied to the inner circumferential surface of the hollow roll 1.   FIG.  2 is a graph of the resulting forces K arising in the sections of length corresponding.  zones 13 and acting on.  the inner circumferential surface of the band and varying with the pressure P in the longitudinal chamber 6.  Consider curve 28, which corresponds to an inter roll pressure of about 50 kPa / cm, which would settle on a roll if zone 13 does not have any effect.  All three zones 13 are now free of pressure.  At P 0, t. e.  in the absence of pressure in the longitudinal chamber 6 (fig.  7), a positive force value is obtained along curve 28, tons. e.  force directed to the gap between the rollers, due to the fact that the zone; 13 along its length do not completely overlap the length of the longitudinal chamber 5 along the circumference, as well as along the length of the zones 13, due to the presence of areas between them (pos. 29), which are under pressure from the longitudinal chamber 5, which is pressed in these places.  rolls roll 2 to roll 1.  Since the pressure in the longitudinal kA measure 5 presses the composite roller against the gaps between the rollers, increasing the inter-roll pressure in the longitudinal chamber 6 reduces the inter-roll pressure.  The actual pressure in the gap between the rolls on the material being processed depends on the difference. hydraulic pressures in the longitudinal chambers 5 and 6.  So, it is possible to obtain one and all cross-roll pressure at different values of absolute pressures in longitudinal chambers, for example, a certain linear pressure is set at a pressure of 6 atm in a longitudinal chamber of 5 and 3 atm in a longitudinal chamber 6 You set the same pressure to 1 s and P1 ) And a pressure of 18 atm in a longitudinal chamber of 5 and 15 atm in a longitudinal chamber 6.  The distribution of linear pressure along the gap between the rolls is no longer perfect, but it turns out to be n: to the W-line in FIG.  3  The purpose of the autonomous zones 13 is to make the W-line more direct, so that the oscillation of the even roll-over distribution is uniform. the appearances were not so big.  This is achieved by the fact that the hydraulic pressure in the autonomous zones 13 decreases relative to the hydraulic pressure in the surrounding longitudinal chamber 5, for example, by 2 atm.  When in source 7 support.  pressure is 6 atm, in zones 13 it is co-.  . it would be 4 atm, and in the case when the source7 produces 18 atm, then in zone 4 it is 16 atm.  As follows from FIG.  2, with a certain decrease in pressure in zones 13, for example, by 2 atm, it is possible to influence the roll bending line by selecting the pressure level in the longitudinal chambers.  With a low level of pressure in the longitudinal chambers 5 and b, for example 6 atm in the longitudinal chamber. 5 and 3 atm in the longitudinal chamber 6, the decrease in pressure on the two atmospheres in the autonomous zones 13 is made less noticeable than at a high level of pressure in the longitudinal chambers, t. e.  at 18 atm in chamber 5 and 15 atm in chamber 6.  The force is reduced when the pressure increases in the longitudinal chamber 6.  In order to maintain the inter-roll pressure of the required value, the pressure in the longitudinal chamber 5 must be increased.  Since zones 13 in the longitudinal chamber 5-, in which there is no pressure, are confronted with mirrored zones located in the longitudinal chamber 6, in which there is now an increased pressure P, with increasing of which components appear that act opposite to the initial value forces k, reducing force K of longitudinal sections corresponding to zones 13, and finally even making it negative, with a corresponding increase in Pressure P roll 2 on the longitudinal sections corresponding to zones 13, deviate from the previous gap between the shaft kami.  Only by adjusting the pressure, provided that the interpolar pressure is maintained, can the influence of zones 13 be used, starting from the pressure of the longitudinal chamber 5 acting on them, and by means of a prolonged gradual decrease in pressure in zones 13, even reach the pressure of the pressing force of the roller 2 .  Curve 29 shows the same conditions if it is assumed that the inter-roll pressure is 100 kPa / cm.  The initial force 30, which is established in the absence of pressure in the longitudinal chamber 6, is naturally twice as large as the initial force 28.  Curve 31 is valid for a linear pressure of 50 kPa / cm when both the outer zones 13 (Fig.  7) through the channel 16 is connected to the reservoir 7.  The slope of this curve is less, because the dale uchas. There is less pressure here, and sweat is also less influenced by areas that are mirrored on the opposite side, under pressure P.  Curve 32.  shows the dependence under the same conditions, but using the / stroke from the linear pressure of 100 kPa / cm.  FIG.  3 shows the most common case in which the upper roller 1 is a massive solid body, and the lower roller 2 has three pressure relief zones 13 formed by plungers located on the side of the gap between the rollers.  , First, consider the case when zones 13 do not work.  Then, in spite of the uniform pressure in the lower roll: e 2, performed as a floating one, it does not give a uniform distribution of the multi-roll pressure.  This should be attributed to the different bending lines of the composite roller 2 and the massive roller 1.   FIG.  3 shows the roll pressure distribution / L.  n the length of the roll gap.  The pressure and pressure curve is calculated by the finite element method of deviations of the lines of bend of rolls 1 and 2 one from another.  The course of these deviations along the gap between the rolls leads.  close to the change in roll-over pressure.  It turns out so called W-line, m.  e.  the distribution of inter-roll pressures, when in the middle and at both ends there are greater values than in the intermediate pressures.  In order to make it clear. the origin of this curve, it is advisable to proceed from the process of initial installation of both rolls.  Lower roller 2, due to its properties, can be mounted directly.  The upper roller 1 sags down in the middle of its weight.  When installing the rolls, they first come into contact in the middle.  Also, the inter-roll pressure is initially higher in the middle than at the ends.  As the necks of the rolls approach, both rolls are adjacent to each other along the entire length, with an increased pressure in the middle.  When increasing the pressing force, the fit occurs mainly at the ends, since they at the roll 1 can deviate to the least degree.  Towards the middle, the inter-roll pressure decreases as roll 2 bends upwards.  Together with the increase in the inter-roll pressure in the middle caused by its own weight.  The curve of the distribution of the linear pressures is obtained, represented: The injection in FIG.  3  /.  .  If now zones 13 of reduced pressure are provided at given locations, then something is taken away from the forces caused by the presence of pressure fluid in chamber 5.  As a result, the roll-over pressure is somewhat compressed: the pressure in these places and in their environment.  The locations of the zones 13 correspond to the locations of the highest inter-roll pressure, which are aligned in this way so that large deviations (Fig.  3) are aligned in a uniform distribution of inter-roll pressure.
