Development of Hot-strip Crownmeter Using γ-ray

Abstract

Strip crown measurements have been requested by strip mills for the production of uniform strip. An online strip crown meter has been developed using Am γ-ray. This paper deals with the problems for the development of the crown meter. Main features of this instrument are using relatively large radiation source and narrow rectangular γ-ray beam. It takes about one minute to scarm entire with of strip, and the accuracy of two microns of thickness was obtained.
