Critical comparison of different techniques for producing profiled wires

Abstract

Abstract. Profiled wires manufactured by the drawing and rolling processes are widely used for production of industrial screens used in the particles separation processes. The main goals in the production processes of such screens are to obtain increased durability and surface quality due to its demanding working environment i.e. high abrasive wear and aggressive condition. The present studies were focused on the analysis of the effects of applied wire drawing and rolling processes on the mechanical properties and surface quality of the produced profile wires. The differences in the schedules of the metal forming processes as well as in the deformation inhomogeneities in the drawn products were analysed. As a result of the applied deformation methods, different surface quality and mechanical properties were obtained. The rolling process has been shown to provide better surface quality and a lower YS/TS ratio, which is critical for further deformations such as the bending process of round industrial screens. The investigations were preformed using austenitic stainless steel.
