Sažetak

In this study, the authors present the results of their theoretical and experimental analysis of the rolling process of Cu – Al bimetallic bars in elongation passes. The original bars were round aluminium bar, covered with copper layer. For theoretical tests, the Forge2008® computer program was used, based on FEM. The model simulated metal flow during rolling of bimetallic bars in oval – round passes. The results of the experiments were compared with the finite element calculations. The analysis demonstrated that an appropriate selection of shape and size of oval pass allows production of even distribution of the copper layer in the bimetallic roll products.
