Abstract
PURPOSE: To permit a distortion detection with high accuracy by providing at least one unit for detecting the stress in the width and rolling directions midway in the width direction, and arranging a plurality of units for detecting the stress in the rolling diretion in parallel in the width direction.
CONSTITUTION: A detecting unit 20 for the width and rolling directions comprising an exciting coil 1, U-shaped cores 7 and 8 and detecting coils 2 and 3 is arranged in the center, and on both sides thereof, a plurality of detecting units 30a... for the rolling direction are provided each comprising an exciting coil 15, a U-shaped core 14 and a detecting coil 16. When a steel plate passes with a gap between the end of each core, the voltages of the detecting coils 2, 3, 16, 18... vary according to the wavy distortion resulting from the unvenness of the internal stress. Said output voltages are rectified by means of rectifiers 21a, 21b, 31a.... The differences E20, E30a, E30b... between them and the DC voltage of the detecting coil 3 are the stress detecting voltages of the respective detecting units. The output voltage in the normal condition is previously balanced by means of the variable resistor of each rectifier circuit. Thereby, a distortion detection of high accuracy is made possible.
