摘　　要：超快冷技术是用新一代TMCP工艺理念开发低成本高性能钢铁材料的核心。热轧板带钢轧后工艺控制点温度的控制精度是保证带钢性能和质量的关键因素。基于前期开发的装备和工艺建立了超快冷自适应控制系统模型,并对模型的自适应功能进行了研究,旨在进一步提高轧后工艺控制点温度的控制精度。通过对模型结构的优化设计、模型自学习控制策略的研究及模型自学习系数加权平滑的处理,增强了模型自适应功能。该控制系统已经成功应用于热轧板带钢生产线。现场实践表明,该系统轧后工艺温度控制达到了较高的精度,为产品质量的提高及新产品的开发提供了有力的保证。Ultra-fast cooling technology which is the kernel of NG-TMCP to develop low-cost and high-performance steel materials,and the control point precision of the process temperature after rolling is the key factor to guarantee the performance and properties of the hot rolling strip.The self-adaptive control model was constructed and studied based the early developed equipment and process in order to improve the control precision of the process temperature.Owing to the optimal design of model structure,study of self-adaptive control strategy and weighted smooth handling of learning coefficients,the self-adaptive function of the system was enhanced significantly.The high control precision and stable performance has been proved since the control system used in the hot strip rolling line successfully,which proves a solid foundation to improve high performance steels and develop new steel product.
