    This invention relates to the automatic regulation of the transverse thickness variation during the rolling of metal strips. The purpose of the invention is to improve the accuracy of controlling the thickness and quality of rolled strips. The essence of the invention is that at the exit of the strip from the rolling stand, a number of thickness gauges are installed on the strip line, the outputs of which are connected to the inputs of the strip controller, the code of which is connected to the input of the pressure regulator. The device also contains two gauges for the position of the support roll, made in the form of a roll with adjustable deflection and containing a cylindrical sheath fixed in the frame, on which the cylindrical shell relies by means of hydrostatic support elements, the outlets of which are connected to the corresponding inlets of the pressure regulator, the outlets of which are connected to the inlets of the hydrostatic support elements. The gauges of the position of the support roll are installed on the inner side of its cylindrical shell at both ends in the plane of reduction with the possibility of measuring the distance between the inner surface of the cylindrical shell and a certain podzgshek point or traverse. 2 hp f-ly, 5 ill. from € cl :)

    专利说明:

    The invention relates to devices for rolling a strip material using a rolling stand with two-side and two support rolls, at least one of the support rolls made in the form of a roll with adjustable deflection and has a yoke supported in the stand of the stand and rotating around it. and a cylindrical o-barrel supported on it by means of hydrostatic support elements. ,,
    The aim of the invention is to measure the distance between the inner surface of the cylindrical shell and a specific point of the crosshead or stand coils, to improve the accuracy of the thickness control and the quality of the rolled strip.
    Figure 1 shows the rolling stand, the cross section along the plane of reduction; Fig. 2 shows the arrangement of the position meter of the backup roll; in FIG. 3, a rolling stand, per section, perpendicular to the roll axis; on - the second example of the rolling stand, section; Fig. 5 shows a device for rolling a strip material.
    The rolling stand (Figures 1-3) consists of a bed 1 in which two working rolls 2 and 3 are rotatably mounted with pillows 4 and 5. A working gap 6 is formed between the working rolls 2 and 3. The working rolls 2 and 3 in during the rolling process, two supporting rollers 7 and 8, located on both sides in the plane of reduction, are pressed against each other, which, in turn, are installed in the frame 1 with the help of pillows 9.
    The support roll 7 is made in the form of a roll with adjustable deflection and consists of the y-beam Y, which is installed in the hinged supports ax 1 in the pillow 9, and the cylindrical shell 12 rotating around the yoke 10 and supported on it by means of hydrostatic support elements 13, which are fed by the working fluid on the pore pipe line 14. Under the pressure of the working fluid, the cylindrical shell I2 presses in the plane of reduction onto the work roll 2.
    The other support roll 8 can be made in the form of a conventional metal roll or also in the form of a roll with adjustable bends similar to roll 7, Instead of a roll in the form of rolls with

    adjustable deflection can perform work rolls 2 and 3.
    The measurement of the working gap 6 and, consequently, the thickness of the rolled material is carried out using the gauge 15 of the support roll position, which measures the position of the inner side of the body of the cylindrical shell 12 of the support roll facing the cross bar 10. It is advisable to provide for one such The meter 15 positions the backup roll on both edges of the casing of the cylindrical shell 12 and connects them to the adjusting device. Using as an adjustable parameter the position of the inner surface of the body of the cylindrical sheath 12 of the support roll has the advantage that neither the elastic stretching of the bed and the underlays nor the deflection of the support rolls affect the measurement result, but only very small flattening of the work rolls affects which can be neglected. The meter 15 of the support roll position during the rolling process is protected from environmental exposure. There is also no danger of damage when replacing the work rolls.
    In principle, any displacement sensor, such as a non-contact sensor, can serve as the gauge 15 of the support roll position. Figure 2 shows the structure and location of the inductive position sensor. It has a fastening element 16 connected to the cushion 9 with a protrusion 17 on which the inductive sensor 18 itself is attached. The cup-shaped part 19 associated with it with the coil spring 20 is pressed against the smooth track on the inside of the casing of the cylindrical shell 12. The distance from the sensor 18 to the component 19 is measured and a corresponding signal is output to the regulating device.
    In the example of FIG. 3, in which both support rolls 7 and B are made in the form of rolls with adjustable deflection, one meter 15 is provided for the position dp of each of the support rolls 7 and 8. While meter 15 is the position of the upper support roll 7 uses as a base the corresponding pad 9, the meter 15 of the position of the lower support roll .8 is not associated with the corresponding
    the cushion 9, and the mechanical connection (tg) 21 is rigidly articulated with the same base as the gauge 15 of the position of the upper support roll. Thus, the effect of deformation of the pads on the measurement accuracy is eliminated.
    In the example of FIG. 4, the effect of deformation of the pads is eliminated by the fact that both gauge 15 positions of the lower and upper support rolls by means of the clamping devices 22 and 23 are mechanically or hydraulically clamped in the frame of the rolling stand. In this case, the intermediate part of the rack between the clamping devices 22 and 23 serve to mechanically connect the measurement bases of the meters 15 of the support rolls. Since the deformation of the stand between these two points is small, it only slightly affects the measurement results. In any case, correction is easy to implement. One of the gauges can also be clamped in the frame, and the other through the mechanical connection to rest on the first, as on {; ig.3.
    I.
    Fig. 5 shows a device for rolling a strip material, containing a rolling stand with work rolls 2 and 3 and support rolls 7 and 8, at least one of the support rolls being made in the form of a roll with adjustable deflection and supported cage traverse 10 and rotating around it and supported by hydrostatic support elements 13 cylindrical sheath 12, gauge 15 position of the support roll, pressure regulator 24, strip thickness gauge 25, support roll position regulators 26 27 strip profiles, the outputs of the gauges 15 of the position of the support roll are connected to the inputs of the corresponding peVil topov 26 positions of the support roll, the outputs of which are connected to the inputs of the pressure regulator, the outputs of which are connected by means of lines 14 to the hydrostatic support elements 13, the outputs of the gauges 25 the strips are connected to the inputs of the regulator 27
    strip profile, the output of which is connected to the input of the pressure regulator 24.
    The device works as follows.
    In the event of the occurrence of thickness variations across the strip, the strip thickness sensors 25 independently control the individual hydrostatic support elements 13 and eliminate the transverse thickness variation.
