Based on physical metallurgy rules and experiential equations, a module for calculating microstructural evolution in the metal hot-forming process has been developed in this article. Meanwhile, with practical technologies of some plant integrated, a coupling multi-variable simulation model for hot strip continuous rolling (HSCR) has been built using non-linear rigid-viscoplastic finite element method (FEM). After an actual 2050 mm HSCR process on JIS-SS400 was simulated using the above model, evolution laws of strain, temperature and microstructure were analyzed. Simulated results of rolling force, temperature and microstructure have a good agreement with the measured values.
