In order to analyze the reasonability of the existing shaped-metal rolling process, the microstructure evolution and the rolling force must besynthetically considered. This paper proposes an integrated numerical analysis procedure to simulate the multi-pass rough rolling process of H-beam, establishes a high-temperature yield stress model and an austenite-grain evolution model based on the thermal simulation and the metallographic observation, and presents a multi-pass simulation method through a re-meshing procedure. Simulated results of an 11-pass rough rolling process of a typical-size H-beam show that the calculated rolling force accord well with the measured ones, and that the austenite grains at the web can be apparently fined after the rough rolling.
