Abstract

PURPOSE:The titled detector which can detect the thickness of the strip without stopping the temper rolling mill, because of being constituted so as to detect the thickness of strip through measurement of the temper rolling load. CONSTITUTION:While the reducing rolls 5, 6 are biting the off-gauge part of the strip 7, the output of the rolling load detector 10 is larger than the set value of the comparator 11, so that the comparator 11 does not produce the stop signal to the motor 8 which hence continues the work at the specified speed. Next, when the reducing rolls 5, 6, bite the ON-gauge part of the strip 7, the output of the detector 10 is smaller than the set value of the comparator 11, which hence produces the signal to stop the motor 8. Accordingly, the range of the OFF-gauge part can be easily judged and the strip 7 can be automatically stopped.
