Abstract：Schedule-free rolling is the necessary way to realize flexible integrated production organization and pursue the maximum production efficiency. Profile contour and flatness control(PCFC) is always a bottleneck problem restricting the schedule-free rolling of electrical steel. The international research on the new generation high-tech wide strip rolling mill types and the technical characteristics of the PCFC and its increasing complexity were described. Based on the thermal simulation and mathematical model, the high-temperature constitutive relationship of the entire rolling process of electrical steel was established, the integrated simulation model of the thermoplastic deformation process of electrical steel was established, and the asymmetric self-compensating rolling action mechanism which can simultaneously control the uneven deformation and uneven wear of entire rolling process of electrically steel was original constructed. A high-precision fusion control method of non-symmetrical self-compensating roll contours, hydraulic roll shifting system and hydraulic roll bending system driven by data and mechanism was proposed. Combined with the production practice, the new generation high-tech PAI(PCFC All-in-one Integrated, “π” briefly) hot continuous strip free-schedule rolling process of full profile contour and flathess fusion π model and PCFC innovation technology were proposed for the breakthrough implementation of the high-precision PCFC in schedule-free rolling process of electrical steel with high efficiency and low cost, which provides a theoretical basis and innovative realization path for the industrial production. Finally, the innovative development trend of high-precision PCFC for wide electrical steel was prospected.
