    Abstract

    Various experimental methods have been used to show the effect of different Sendzimir mill rolling parameters on stainless steel strip shape. Experiments using sister coils, noting the effects of change over a number of coils, and using the "Taguchi" statistical experimental design techniques have been carried out. Work has been carried out on individual rolling presses and on complete rolling sequences. Strain measurements have been used to show the behaviour of a statically loaded work roll, and the vertical and horizontal bending of a roll were investigated. From this work the effects of the axially adjustable first intermediate rolls on the strip shape have been further investigated. The parameters that affect strip shape have been identified and stated in order of the magnitude of their effect. The adjustments that are needed to improve specific strip shape defects have been identified. It has been established where rolling parameter alterations have an interacting effect with other rolling parameters. Recommendations have been made that will improve the rolling process to enable a more consistent and better product, over a limited material range, to be rolled. Consideration has been given to new roll shapes and roll bending has been related to specific strip shape. Recommendations have been made to improve the rolling process so as to attain flatter strip.
