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 continuously improve the quality of cold-rolled products, the National Engineering Research Center of High-Rolling University of Science and Technology of Beijing University of Technology independently developed the cold-rolling automatic control system. L2 adopts the process control development platform, integrates the load distribution model with various targets and various mathematical models of deformation resistance , Plate / plate thickness distribution decoupling compensation strategy, deformation resistance self-learning model, obtained a high-precision cold-rolled mathematical model to achieve a self-optimizing system; L1 using ultra-thin format dynamic pressure technology, core eccentricity compensation Technology, shape / thickness control strategy decoupling, etc., to achieve a high-precision thin-gauge cold-rolled strip steady rolling. Application results show that these new technologies are fully qualified for the stable production of 0.2 mm cold rolled strip with a thickness deviation controlled within ± 2 μm and a significant improvement in product yield and product quality.
