Abstract Simulation technology can realistically simulate the real world, cultivate students’ innovative practice ability, improve practical teaching effect. In view of the problems existing in the practical teaching of materials processing and controlling engineering, we designed a flatness control practical teaching platform based on simulation technology. The development of practical teaching platform divided into five modules: raw material preparation, rolling process control, flatness control foundation, flatness control strategy and flatness control training. The five modules contain all aspects of flatness control, and introduce from point to surface, from shallow to deep. The rolling temperature and thermal crown simulation were taken as examples, the process of modeling and simulation were introduced in detail. The teaching platform can stimulate students’ interest of learning, improve students’ practical ability, also can make the students handle the complex rolling conditions and the complex flatness control conditions.
