摘  要:为了不断提高冷轧产品质量,北京科技大学高效轧制国家工程研究中心自主开发了冷轧自动控制系统,L2采用过程控制开发平台,集成多种目标的负荷分配模型、多种变形抗力的数学模型、板形/板厚分布计算解耦补偿策略、变形抗力自学习模型等,获得了高精度的冷轧数学模型,实现了自优化系统;L1采用超薄规格动态压下技术、卷芯偏心补偿技术、板形/板厚解耦控制策略等,实现了薄规格冷轧带材的高精度稳定轧制。应用效果表明,这些新技术完全胜任0.2 mm冷轧带材的稳定生产,厚度偏差控制在±2μm以内,产品成材率和产品质量大幅度提高。In order to improve the quality of cold rolling products,an automatic control system for cold rolling is independently developed by National Engineering Research Center for Advanced Rolling Technology of University of Science and Technology Beijing. The multi-target load distribution model, the mathematical model of various deformation resistance, the decoupling compensation strategy for shape/thickness step-by-step calculation, the self-learning model of deformation resistance, etc. are integrated in the L2 system,which uses a process control platform,to achieve the mathematical model of the high precision cold rolling and the self-optimizing system. The dynamic reduction technology for ultra thin products, the roll core eccentricity compensation technology, the shape/thickness decou-pling control strategy,etc. are integrated in the L1 system to achieve stable and high precision rolling of thin strips. The application results show that these new technologies are fully qualified for the stable production of 0. 2 mm cold rolling strips,the thickness deviation is controlled within ± 2μm,and the yield and quality of products are greatly improved.
