Abstract: Heat resistant steel is a new type of martensite heat-resistant steel which has the very high temperature comprehensive performance and wide application. Now integrating practical experiments with the simulation of finite element analysis software DEFORM-3D. Research on the forming process of heat resistant steel by cross wedge rolling. Obtained the distribution laws of microstructure in cross-longitudinal planes of after rolling steel, and the influence law of different technology parameters affects steel dynamic recrystallization volume fraction and austenite average grain size. Finally, combining the experiment of metallographic structure, and validate the validity?feasibility of the simulation.
