摘　　要：在超薄快速铸轧条件下 ,板形控制成为实现超薄快速铸轧工艺规程并最终保证产品质量的关键 .板形与力辊型、热辊型、布流等众多因素及这些因素间的互相耦合等有关 ,板形控制模型难以建立 .为此 ,作者研究一种基于人工神经网络技术的超薄快速铸轧过程板形控制方案 .该方案采用模块化的设计方法 ,以西门子可编程序控制器PLC作为底层控制单元 ,以工控机作为上位机实现铸轧过程的板形监控 .实验结果表明 :该方案实现简单 ,通讯可靠 。In thin gauge high speed roll casting process, flat control is the key technology for realizing the thin gauge high speed roll casting and ensuring the product quality. The flat is affected by many factors such as pressure roller, hot roller, flow distribution, and these factors affect each other. So it is very difficult to build the control model. In this paper, flat control system based on neural network for thin gauge high speed roll casting process is introduced. In this system, modularized design method is adopted, the PLC is the lower control cell, and the computer is used to control the roll casting process. This project can be realized and transplanted to other control systems easily, suitable to similar industrial control system, and the communication is very dependable.
