简要介绍了唐钢1 800mm 5机架冷连轧机组的工艺参数、仪表配置及过程控制模型设定系统。从轧制过程在线数学模型、基于成本函数的多目标优化负荷分配和模型自适应3个方面对该冷连轧过程控制模型设定系统进行了深入分析研究。现场应用表明,该L2过程控制系统运行稳定,模型设定系统制定的轧制规程合理、模型设定计算具有非常高的精度,满足在线控制的要求。
Briefly introduces the process parameters, instrument configuration and process control model setting system of 1 800mm 5 cold tandem mill in Tangsteel. From the mathematical model of the rolling process on-line, based on the cost function of multi-objective optimization load distribution and model adaptation of the cold-rolling process control model setting system in-depth analysis and research. The field application shows that the L2 process control system runs stably, the rolling schedule established by the model setting system is reasonable, the model setting calculation has very high precision, and meets the requirements of online control.
