To implement the new generation thermo mechanical control process (NG-TMCP), the automatic control system of ultra fast cooling (UFC) was developed by combined with the renovation project of controlled cooling system in one plate production line. This system was composed of basicautomation subsystem and process automation subsystem. As the main control unit of the basic automatic control system, a S7400 PLC system is used to control the UFC device and to achieve the chain control between the UFC system and the mill system. While the process control system is to realize the automatical setting of the cooling schedule by the developed finite element temperature field model and the temperature homogeneity model. The industry application shows that the NG-TMCP which is based on the UFC can reduce the alloy content effectively and implement the low-cost reduction produce of high-grade products.

The automation control system to plate production line is developed independently. It has been applied several plants in China and has a good effect. The whole automaton control system is designed as several levels: basicautomation. system process, automationsystem. and HMI system. The control functions are realized with these levels. With AGC function in plate mill area basic automation system, the plate thickness accuracy can be guaranteed.

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 automationsystem 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 automationsystem. 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.
