Abstract: A two-level process control system was developed independently and applied to the 3500 mm plate mill in Shougang in Beijing. Covering such functional modules for data communication, management, process tracking and model computation, they are used correspondingly for data communication among the process control system and other system; database reading/writing, model parameter querying for computation and actual process parameter recording for each and every workpiece, position/data tracking for workpieces to actuate other functional models at different points so as to control/schedule all workpieces automatically, and model computing for pass schedule and cooling system control. With those modules working collaboratively, a model-adaptive and fully automatic rolling control is available, which has been used in site successfully.
