- Abstract
- To investigate the distribution law of microstructure during stretching stage for cross wedge rolling of asymmetric shaft parts, so as to achieve a coordinated forming control of shape and quality in cross wedge rolling of asymmetric shaft parts, we employed the finite element method in this paper to simulate the process of cross wedge rolling of asymmetric shaft parts. By studying the dynamic recrystallization volume fraction and the average grain size distribution in stretching stage as well as comparing the average grain size of asymmetric rolling and symmetric rolling, we achieved the high temperature austenitic grain size distribution during stretching stage for cross wedge rolling of asymmetric shaft parts, then conducted the corresponding experimental verification. The study results have important scientific significance and engineering application value for the rolling technology innovation of cross wedge rolling shaft parts by enriching and improving the theory of cross wedge rolling of asymmetric shaft parts, reducing the production cost and improving the quality of rolled products.
