Finite element software was used to analyze the deformation of hot extrusion technology at high temperature and high speed for super-alloy Inconel 690(IN690). It had been obtained that the temperature filed and strain filed and stress field during tube extrusion deformation at different speeds and temperatures. The results presented that deformation uniformity being fine and the temperature variety increased with increasing of extruding speed. The maximal equivalent stress decreased and the distributing was further uniformity with the increasing of deformation temperature. Extrusion force reduced at first and then increased with increasing of extruding speed. Maximal extrusion force reduced with the increasing of deformation temperature. The relative errors of extrusion force between simulating results and experiment results are less than 7.3%. Extrusion technology parameters for supper-alloy Inconel690 had been optimized which are that extrusion speed being 110 ~ 120mm / s, and extrusion temperature being 1200 °C. |
