    专利说明:

    The invention relates to the field of measuring the thickness, width and flaw detection of surface cracks of strip steel in rolling mills.
    It is known (GDR patent No. 160322, class C 01 B 7/02, 1981) a device for measuring the thickness and width of steel strip containing a base with an adjustable piece attached to it and a measuring sensor holder. The adjustable part consists of two parts, which are interconnected on each side by two pivot levers mounted on the axles. The levers are parallel to each other and set at an angle ui with a horizontal between 45 and 75. The pneumatic or hydraulic working cylinder connects the shortest way to the upper axis of one lever with the lower axis of the other, two opposite vertical cantilever rollers on both sides of the cross-section of flat steel are installed in the lower part, followed by a horizontal roller with a conjugate roller in the upper part. The holder of the measuring sensors has two opposing measuring sensors, one installed above and below the cross section of the steel sheet.
    However, due to the beating or vibration observed after the steel sheet leaves the last rolling stand, the accuracy of the measurement results deteriorates.
    Further, the probability of accidents increases and, therefore, the productivity of the rolling mill is not high. This also applies to flaw detection of surface cracks. The aim of the invention is to improve the reliability of the assessment of the quality of the strip steel, the reliability of the rolling mill and the efficiency of the production of strip steel.
    The goal is achieved between a device for measuring the thickness and width of strip steel and hot cutting shears or between a device for flaw detection of surface cracks and hot cutting shears, a centering device controlled by a rolling material detector is installed, and that the distance between the device for measuring thickness and the width of the strip steel and

    the centering device is variable, and the distance between the device for flaw detection of surface cracks and the centering device is not changed.
    In addition, the first disk of the centering device is barrel-shaped, and the second is of a cylindrical shape or vice versa, and also with the possibility of 10 vertical movements of the first disk of the centering device.
    Figure 1 shows the functional diagram of the device; figure 2 - section aa in figure 1.
    The device contains the last rolling stand, the device 2 for measuring the thickness and width of the strip steel, followed by the device 3 for flaw detection of surface cracking and the centering device 4, which contains two discs 5 and 6. The indicator 7 of rolled material is placed in front of the hot steel shears 8 lanes 9.
    The device works as follows.
    in a way. . I
    The rolled material warning device controls the mechanisms for opening and closing the device 2 for measuring the thickness and width of strip steel, the third surface flaw detector device 3 and the centering device 4. When the rolled product warning device 7 is moved, the mechanisms can be controlled independently of the centering device 4 rolling speeds if the distance
    40 between the centering device 4 and the signaling device 7 of the rolled material corresponds to the kinematic conditions of the control process. When placing the annunciator 7, rentals45 Baynoy material in front of the centering device 4 control mechanisms for opening and closing depends on the rolling speed. The positioning of the indicator 7 of the rolled material depends on the kinematic conditions and on the control of the entire rolling mill. The distance between the rolling mill and the device for measuring the thickness and width of the strip
    55 steel is a constant value, and the distance between the device 2 for measuring the thickness and width of the steel strip and the centering device may vary. Distance
    3
    The distance between the rolling stand 1 and the flaw detection device 3 for surface cracks is variable, but the distance between the device 3 for flaw detection by surface cracks and the centering device 4 is kept constant. Variable distances depend on the rolling program, i.e. B, depending on the cross-section of the steel strip 9, it leaves the last rolling stand of the finishing section of the rolling mill. The rolling stands 1 not involved in rolling do not work. In this case, flaw detection of surface cracks is always performed beyond the last rolling stand 1 of the finishing section. The thickness and width of the strip steel are measured directly behind the last rolling stand 1, which is in contact with the steel strip. The centering device 4 is designed so that it rotates synchronously with respect to the speed of exit of the steel strip 9 from the rolling stand 1 and with little effort pulls the steel strip from the rolling stand.
    The first disk 5 and the second disk 6 are connected to the drive, with the first disk moving in a vertical direction. The first disk 5 is barrel-shaped, and the second disk 6. has a cylindrical shape (figure 2). Reverse execution is also possible. The compression forces of the centering device are recorded by mechanisms not shown. The grip of the front end of the steel strip 9 is performed in the closed state of the centering device 4 and all guiding mechanisms in the measuring sections of the device 2 for measuring the thickness and width of the steel strip and the device 3 for flaw detection of surface cracks. The centering device 4 is closed only when the front end of the steel strip 9 goes into the guide groove behind the centering device 4. If the centering device 4 is closed, then all the other named guide mechanisms are closed. The centering device 4 and the remaining guiding mechanisms open after passing the steel strip 9 through

    the centering device 4, if the rear end of the steel strip has passed through the signaling device 7 of the rolled material. Depending on the duration of the technological operation during the rolling process, the response time of the control unit is selected to open and close the centering device 4 and the other guide mechanisms.
    The invention eliminates the runout and misalignment of the steel strip and thereby creates optimal conditions for measuring and testing the steel strip 9. 5 Hinging the steel strip 9 with a centering device 4 almost completely eliminates the occurrence of accidents, which ensures efficient production of strip steel.
