Abstract

PURPOSE: To aquire a plate thickness measured value which is precise along the overall length of a thick plate in the rolled direction and good in absolute precision by correcting a detected signal of a thickness meter using a non- contact optical range finder by a gamma-ray thickness gauge.
CONSTITUTION: At the time of measuring plate thickness of a thick steel plate 6 being rolled by a rolling mill 17, a measured value of a gamma-ray thickness gauge 1 which is good in absolute precision and a measured value of a thickness meter 3 using a non-contact optical range finder which is good in relative measuring precision of high speed sampling are input to a multipoint plate thickness arithmetic circuit 10. The multipoint plate thickness arithmetic circuit 10 high- speedily acquires a plate thickness measured value which is good in precision by correcting the measured value of the thickness meter 3 by the measured value of the gamma-ray thickness gauge 1. This corrected plate thickness is output as the plate thickness measured value.
