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.
