The combination of the conventional forming processes rolling and extruding enables the continuous production of cross-sectional aluminum long products. Due to its continuity, the combined forming process is more efficient compared to its conventional alternatives. The combined rolling and extrusion process is at an early stage of maturity. The production of pure aluminum wire is state of the art. For the production of complex cross-sections, a better understanding of the material flow within the process is necessary. This paper describes the results of numerical and experimental investigations regarding the material flow of the combined rolling and extrusion process. The finite elements method was used to simulate the material flow within the process. The simulated results were compared to an experimental visioplastic examination of the process. The results of the visioplastic examination show some specific material flow characteristics linked to the combined rolling and extrusion process. The results of the numerical simulation and the experimental investigations are in good agreement. The finite elements method can be used to reproduce the material flow within the examined process and its specifics.
