Main objective was the development of an innovative strip finishing procedure by combining tension levelling and skin pass rolling into one production step and thus to shorten the process chain. It could be proved that the mechanical characteristics of strip material mainly adjusted during the skin pass rolling process are possible to be achieved as well during a pure tension levelling process by variation of applied tension and bending load. The realisation of the desired surface texture requires an additional superposed deformation under pressure introduced simultaneously in those strip sections where the yield strength of the material already is met by the applied tension-bending procedure. Using the new facility it will be possible to adjust material mechanical and surface roughness properties independently. Thus the new technique fundamentally contributes to the common development to require steel grades with highest surface quality and simultaneous highest available deformation resources.
