Development and application of automation control system to plate production line

The automation control system to plate production line is developed independently. The whole system is divided into several levels and control functions are put into effect by the basic automation system, process automation system and human-machine-interface (HMI) system. Plate production thickness accuracy depends on the Automatic Gauge Control (AGC) function in the basic automation system for the plate mill area. With date communication module, process tracking module, data management module, and model calculation module, the core process model setup function is implemented by process automation system. Process monitoring and operation are implemented by HMI system. This automation control system proposed here has been applied successfully to several plate production lines in China with a good effect.
