PFC(profile and flat control) is a core technology in hot strip rolling. In order to improve the quality of the hot continuous rolled strip, precise set up control system must be applied. PFC set up system of a certain domestic 2?050 mill was analysed to set up the main mathematic models and the control principle was discussed. The off line simulation of the system was carried out by adopting the C++ language. By comparing simulation results with measured data, the accuracy of the set up value was verified. Theorem and method of PFC for hot continuous rolled strip were more clearly established though simulation. The research has set a sound base for improving the setting accuracy and for further development of the system.
