摘　　要：自由规程轧制是实现柔性一体化生产组织和追求最大生产效率的必要途径,板形控制一直是制约电工钢自由规程轧制的瓶颈难题。阐述了国际上对新一代高技术宽带钢轧机机型的不断探索与板形控制技术特征及其日趋复杂化的进展研究;基于热模拟与数学模型构建了电工钢完整轧制过程的高温本构关系,建立了电工钢热塑性变形过程集成仿真模型,原创构建了电工钢自由规程轧制完整过程中可同时控制不均匀变形和不均匀磨损的非对称自补偿轧制作用机制、提出了一种由数据与机理融合驱动的电工钢自由规程轧制形性协同的非对称自补偿轧制轧辊辊形、液压窜辊和液压弯辊的高精度融合控制方法。结合生产实际提出了新一代高技术热连轧自由规程轧制过程的全板形融合π机型与板形控制创新技术,突破性实现了高效低成本对新一代高技术宽带钢轧机自由规程轧制的高精度板形控制,为现场工业生产提供了理论基础和创新实现路径。最后展望了宽幅电工钢高精度板形控制的创新发展趋势。Schedule-free rolling is the necessary way to realize flexible integrated production organization and pursue the maximum pro-duction efficiency.Profile contour and flatness control(PCFC)is always a bottleneck problem restricting the schedule-free rolling of elec-trical 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 con-stitutive 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 simulta-neously control the uneven deformation and uneven wear of entire rolling process of electrically steel was original constructed.A high-pre-cision 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 fusionπmodel 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 indus-trial production.Finally,the innovative development trend of high-precision PCFC for wide electrical steel was prospected.
