A dynamic simulation model of a 3-ply paperboard production process was developed. The simulation model consists of stock preparation and proportioning, short circulations, wire and press sections, and 75 drying cylinders including the steam and condensate system. Functionality of the automatic grade change program used on the machine was modeled as well. Physical, first principles models were used whenever possible. Simulator was extensively validated using historical data. The simulator has been used as a test bench in order to find better values for automatic grade change parameters. First set of the new simulator tested parameters has been carried out to the real machine with good results.
