Abstract
PURPOSE: To maintain high-precision measurement by measuring the width of a calibration plate at a prescribed position on a rolling line by a width gauge, and then by adjusting the zero-adjustment resistance of a deviation calibrating circuit via a motor according to the output that corresponds to the deviation of the measured value from the set width of a width gauge photodetector.
CONSTITUTION: Photodetector 2 of width gauge 1' on detection part trestle 12 is set to the width of a rolled material. Calibration plate charging apparatus 30 is put into operation to charge calibration plate 8 at prescribed position A on a rolling line and position detector 42 confirms that it is at prescribed position A. The output of photodetector 2 is sent to control part 6 and if its output deviates from the position of the calibration plate, the output is amplified to adjust the zero-adjustment resistance via a servomotor. Then, calibration plate 8 is moved back to set a steel-plate width measurement state. Thus, the high-precision measurement can be maintained.
