The influence of different work-roll texturing systems on the development of surface structure in the temper rolling process of steel sheet used in the automotive industry

Abstract This article presents a comparative study of the work roll texturing systems shot blast texturing (SBT), electric discharge texturing (EDT), electron beam texturing (EBT) and laser texturing (LT). The functional behaviour of the work roll surfaces used in the temper rolling process is assessed by describing the transfer characteristics specific to the technique used and also the wear characteristics. Painting tests were performed to obtain information on the suitability of the sheet surfaces obtained in this way for further processing.
