Description
Technical Field

Background
In the hot rolling process of the strip steel, the thickness of the strip steel is mostly measured by adopting a radial thickness gauge, and the measured thickness value is used for controlling the rolling thickness of the strip steel by an AGC control system. The radial thickness gauge adopts a C-shaped frame structure and comprises an upper arm and a lower arm. Wherein, the upper arm of the radial thickness gauge is an X-ray source and a high-voltage generator device; the lower arm of the radial thickness gauge is an ionization chamber and a data processing mechanism. To ensure the measurement accuracy, the thickness gauge needs to be calibrated regularly by using a standard plate (i.e. a calibration plate).
At present, current calibrator calibration auxiliary device need rely on artifical manual completion standard plate's location to put usually in calibrator calibration process, including the change work and the location work of standard plate, all are accomplished by manual operation. When the thickness gauge works, the X-ray tube can emit a large amount of X-rays, and the thickness gauge works in an X-ray environment for a long time, so that great harm is caused to human bodies. Therefore, the shutter of the thickness gauge needs to be closed each time before the standard plate is manually replaced or positioned, and subsequent operation is carried out after the X-ray is dissipated. And when one-time full-range and full-channel calibration is carried out, the standard plate is usually required to be replaced or added for hundreds of times, correspondingly, the shutter of the thickness gauge is required to be opened and closed for hundreds of times, the calibration work can be completed usually within dozens of hours, and the time consumption and the long acting rate are low. Taking a hot rolling line multifunctional instrument as an example: 26 ionization chambers with 78 channels and 1-26 mm calibration plates are calibrated once in every 4 channels, the standard plates are required to be replaced or added 520 times in total in the full-range full-channel calibration, and correspondingly, the thickness gauge shutters with the corresponding times need to be opened and closed. In addition, the shutter of the thickness gauge is opened and closed for a short time and at a high frequency, so that the shutter is abraded, the service life is shortened, and in case of the operation of opening the shutter by mistake, a radiation safety accident is caused, and the danger is relatively high.
