Rolls wear characterization in hot rolling process

Abstract : This paper is based on the hot rolling process on stainless steels. The aim of this article is to characterize the wear of working cylinders during the hot rolling milling process. The behavior of working cylinders, used in a finishing hot rolling mill, is thus analyzed. Because of their large dimensions, the analysis of such tools cannot be carried out with usual laboratory equipment. A non-destructive methodology is proposed using replicas to measure the topography of the working cylinders. Then, two wear processes are distinguished thanks to multi-scale analysis of different roughness parameters i.e. an adhesive wear process and an abrasive wear process. A wear criterion has been defined in order to determine the maximal length of the rolling campaigns before grinding.
