Abstract:
Aiming at the challenge of integrated control of key indicators such as shape, properties, and surface quality in the production of high-quality sheet and strip, the achievements of China in the integrated control technology of shape-property-surface for high-quality sheet and strip were introduced. The strip shape control technologies of multi-modal information fusion detection and multi-stand and multi-process coordination were briefly described from the aspects of straightness detection of hot rolled strip, intelligent prediction system of roll and strip shape state, comprehensive control model of roll bending and axial shifting, and strip shape feedforward control of cold and hot rolling process. The control technologies of hot rolling process and mechanical properties based on large model were briefly described from the aspects of microstructure parameters and mechanical properties control model of hot rollingprocess and pre-control of microstructure properties of hot continuous strip rolling. The intelligent simulation and control technology of high-quality strip surface characteristics was briefly described from the aspects of unsupervised classification detection algorithm for surface defects and comprehensive control of surface defects and characteristics. On this basis, the field applications of these technical achievements were described, and the development of comprehensive control of high-quality sheent and strip was prospected.
