中厚板轧机二级过程控制系统模型的研究与优化

舞钢公司第二轧钢厂轧机二级过程控制系统是新宽厚板生产线的重要组成部分。结合实际生产过程,对该二级系统的温度模型、轧制力模型、扭矩模型以及双机架轧制匹配模型等进行了参数优化调整,进一步提高了系统模型预测数据的准确性,保证双机架轧制模式的稳定运行。

Research and Optimization on the Model of Level 2 Process Control System for Medium and Heavy Plate Mill

The Level 2 process control system of the plate mill in No. 2 Rolling Plant of Wugang is an important integrated part of the new million tonnage wide and heavy, plate production line. On the basis of actual product!on process, the article describes the optimization and tuning on the parameters of important models in Level 2 system iin- cluding the temperature model, rolling force model, torque model and twin stand operation model, which further improves the accuracy of the prediction data in the system models, ensures the stable rolling operation in the twin stand mode.
