Abstract:Medium and high speed tissue paper machines, with running speed higher than 800 m/min, were launched in many enterprises due to market competition intensifying, and the implementation of the policies of energy-saving and low-carbon economic. However many technical problems included beating control, basis weight control, energy-saving of drying section and driving control were needed to be solved. To solve those problems, online soft measurement and control strategy of beating degree, online soft measurement method of basis weight, energy consumption synergistic control algorithm of dryer section and three-points driving control method of driving system were proposed in this study, finally. An integrated optimization control system was developed based on the software platform of WinCC, Step7 and PCS7. The practical running effect showed that the error of beating degree was smaller than ±0.5°SR, and the stock consumption was less than 1.05 tons per ton peper. The precise control of basis weight was realized, without equipping with online quality control system (QCS), the error was lower than ±0.4 g/m2. The average steam consumption of drying section was lower than 2.03 tons. The stable running speed could reach 1300 m/min.
