CONSTITUTION:The output Hi and hi transmitted from the inlet side plate thickness gage 14a and outlet side plate thickness gage 4b of a stand STi is taken into an influence coefficient computing element 5 and also the influence coefficient is outputted by calculating with using arithmetic equation by taking in the observed roll speed Vi-1, Vi as well in the stand STi and stand STi-1. An automatic plate thickness control device 6 takes in the observed plate thickness h1 and influence coefficient, outputs the correction command signal of the roll speed for the stand STi-1 and corrects the roll speed. The plate thickness control of high accuracy can be thus performed by estimating the correction value in the strip plate thickness variation according to the variation in the roll speed difference.,下面是Automatic plate thickness control method专利的具体信息内容。
