On-Line Functioning of Setup Calculation Module in Plate Rolling

How to function the parameter setup calculation in the process control system for plate rolling was studied. The parameter setup calculation was divided into three parts, i.e., rolling scheduling relevant mill setup and control parameters and model learning control, of which the main functions and relations among them were analyzed. The on-line data flow and calling logic of the setup calculation were designed. According to the arrangement of monitors/probes and scheduled rolling technological process, the setup calculation can be called time and again. By means of the presetting and resetting calculations including the modifications of different rolling phases and passes, learning control and holding time, the parameter setup calculation embedded in the process control system of plate mill has functioned as the on-line actual data during rolling.
