摘    要：热连轧生产线具有高温、高速、多品种、高精度等特点。过程控制系统在信息处理、物料跟踪、设定与控制等方面直接影响生产的稳定性与产品质量。本文分析了热连轧过程控制系统的特点和开发难点,并通过自主开发宝山钢铁股份有限公司新建1880热连轧生产线过程控制系统的实践,提出自主开发热连轧过程控制系统需要的关键技术,主要包括根据控制实时性与功能复杂度的设备配置与选型技术、根据产品的品种特性进行出钢记号分类并确定不同物性参数的技术、高精度核心过程控制模型的开发技术以及结合品种与规格拓展的模型参数优化技术等。

Abstract: Hot continuous rolling line is characterized by high temperature,high speed,many varieties and high accuracy.Process control system influences stability of production and product quality directly in the respects of information processing,material tracking,setup and control,etc.Features and development difficulties of process control computer system for hot strip mill are analyzed.Based on practice of process control system for self-developed and new built 1880 hot strip rolling production line of Baoshan Iron & Steel Co.,Ltd.,necessary key technologies for development of hot rolling process control system are proposed.They include equipment configuration and selection technique based on real-time performance and function complex degree of control system,technology for product category classification,development technique for high precise process control model,and model parameter optimization in expanding product mix.
