OnQ FormingSens has a long track record of benefitting paper manufacturers of different grades, with more than 100 systems are already in use in the forming section worldwide. Thanks to microwave technology, the leading solution measures fluctuations in water weight precisely, reliably and in real-time. Based on this information, papermakers can systematically improve their settings, achieve a stable dry content at the end of the forming section, and utilize the maximum dewatering capacity in the press section. At the same time, the optimized settings ensure less wear on the forming fabrics and ceramics. In addition, vacuum and drive energy usage can be reduced, which was confirmed, among others, by a Central European packaging papers manufacturer. Here, OnQ FormingSens reduces energy costs by around 130,000 euros per year and pays for itself in well under a year. For maximum user-friendliness and reliability, Voith experts have now further optimized the design of the solution.

  • Based on many years of experience and profound know-how, Voith improves the design of OnQ FormingSens for optimized lifetime, reliability and operator friendliness
  • Thanks to real-time measurement, the operator continuously receives information about the dry content in the forming section and can optimize the vacuum settings
  • In combination with the OnC.Dewatering automatic vacuum control system, layer bonding in the forming section can be improved and energy requirements reduced

2022 09 19 083919

"Compared to the previous OnQ FormingSens, the new generation has a significantly longer service life, flexible connection options to existing process control systems, and improved mechanical stability, thus enabling extremely reliable measurement results," says the responsible project manager, Jörg Spindler, Manager Actuator Development at Voith Paper. The new design focuses on solid, low-vibration construction, as well as a simplified electrical design. Among other things, Voith's experts reworked the mechanical mount so that the operator can now fine-tune the penetration depth from outside the machine via waterproof mechanical gear. The sensor holder can be flexibly positioned on various existing dewatering elements in the former. Compared to hand-held measuring devices, the permanently installed application is characterized by higher safety, as no direct contact with the operator with the forming fabrics is necessary. An improved sensor housing ensures higher long-term stability. The new generation OnQ FormingSens is installed to a nearby terminal box, which can be serviced by Voith experts via a service connection. This allows the optimized solution to be better connected to customers' existing infrastructures, such as the process control system.

Combination with OnC.Dewatering control system
Based on the measurements of OnQ FormingSens, the control loop can be closed with the fully automatic dewatering control OnC.Dewatering. The control system defines and stabilizes the dry content of each layer produced and thus significantly increases ply bond on multi-ply machines.

The recycling process in paper production is complex. Fluctuations in fiber quality and the degree of contamination of the recovered paper bales have a direct influence on production output. At the same time, resource efficiency is more important today than ever before. However, with the current state of the art, it is hardly possible to determine the specific causes of losses and optimize them directly. Yield is usually only measured on a weekly or monthly basis - by the time paper manufacturers receive the information, the losses have already occurred. Furthermore, it is very difficult to estimate whether losses in individual stock preparation areas have increased or decreased compared to the last analysis. To address these issues, the leading full-line supplier Voith has developed OnView.MassBalance.

The innovative digital tool displays losses in stock preparation in real time to further increase the sustainability and efficiency of paper production. At a glance, the operator can locate the specific areas with optimization potential on the screen. For this purpose, a Sankey diagram maps each feed, accepts and rejects at each process step. As soon as a critical value is reached, OnView.MassBalance reports this to avoid high losses. In this way, standardized processes can be established that can be quickly and easily performed by operators across different shifts. Suitable countermeasures can be, for example, checking the pressure drop or the feed consistency of the last screening stage.

Successful customer installation
"The solution is already being used very successfully, for example in an OCC mill in France with an annual capacity of 250,000 tons,” according to Flavio Granito, Global Product Manager Fiber System 4.0 at Voith Paper. “After the optimization phase, 600 tons of rejects, including raw material, could be saved per month. This corresponds to a two percent improvement in yield.” As there is less rejects to dispose of and at the same time more paper can be produced with the same amount of raw materials, the solution pays for itself in less than a year. Flavio Granito further explains: "OnView.MassBalance is another example of how digitalization can strengthen more sustainable and cost-efficient papermaking. As part of our major sustainability program Papermaking for Life, we have set the goal of optimizing recycling processes and minimizing fiber losses. We aim to achieve a 90 percent recycling rate by 2030."

Installation and operation support
To calculate the mass balance in stock preparation, the innovative tool uses the signals from the sensors installed in the stock preparation plant. Voith experts identify the sensors required for this and develop a suitable concept together with the customer. Voith also separately offers the OnPerformanceLab (OPL) service. Based on bundled know-how, the OPL provides pragmatic support in analyzing losses, defining and implementing new countermeasures, and preparing monthly reports in close coordination with the respective paper technologists.

Current raw material prices are forcing paper manufacturers to reduce production costs and further optimize the efficiency of their production facilities. Digitalization plays a key role in achieving efficiency gains and cutting costs. This is because new technologies in particular enable significant improvements in existing and new plants. They allow better monitoring of all processes and thus more precise production control, which in turn leads to higher efficiency and better availability.

Reduced starch consumptionIn addition to fiber, starch is a major raw material cost factor in the production of packaging papers. Therefore, the goal of paper manufacturers is to reduce starch application and keep the amount of starch as low as possible - without falling below the required quality level.

However, continuous optimization with conventional tools quickly reaches its limits. Paper manufacturers are confronted with the situation that they cannot directly control important quality parameters such as strength, because the measurement of the relevant parameters only takes place at the end of each tambour in the laboratory and the values are not continuously available.

Digital solutions such as OnEfficiency.Strength from Voith now offer the ability to have important quality parameters constantly available thanks to virtual sensors and to have the process optimally controlled automatically.

2022 07 07 191148

How Laakirchen Papier AG optimizes the use of starchSince 2021, OnEfficiency.Strength has been used at PM 10 in Laakirchen, Austria, to optimize starch application. A positive side effect is also the resulting reduction in steam consumption in the after-dryer section. What was previously only possible either through manual measurements in the laboratory or automatic test line measurements is now realized by Laakirchen with the use of virtual sensors: the calculation of data on the most important strength values (SCT CD, CMT and burst).

"This continuous monitoring of important quality parameters enables continuous optimization of the process in terms of cost and quality. Manual laboratory measurements, on the other hand, take up to 30 minutes after sampling, and the parameters can then only be adjusted by manual intervention," says Korbinian Hitthaler, project manager for Papermaking 4.0 at Voith OnPerformance.Lab. "Thanks to the virtual sensors, the strength values are now available in real time, so the starch application can be controlled without losing time. Thanks to the automatic control of the jet-wire difference, strength potentials between MD and CD can be optimally balanced."

Christopher Dierkes-Leifeld, PM 10 technologist at Laakirchen Papier AG, further explains: "We have been using OnEfficiency.Strength since 2021 to consistently meet quality requirements and thus optimize the paper produced on PM 10 and compensate for process fluctuations. At the same time, we have also reduced our costs, because OnEfficiency.Strength enables optimum control of the starch application quantity and the jet-wire ratio.”

Real-time prediction of quality parameters and continuous optimization of the process has not only prevented quality fluctuations, but OnEfficiency.Strength has also enabled production costs to be reduced while reliably meeting quality targets. ”Since we started with Papermaking 4.0 in cooperation with Voith, the speed of our PM 10 has been increased. Nevertheless, we have achieved the strength properties required by our customers with up to 10 percent starch savings due to optimization by the control system," concludes Dierkes-Leifeld. For PM 10, OnEfficiency.Strength helped to save four percent starch in the first year and now up to 10 percent starch in the second year, while key quality parameters such as SCT CD and CMT remained within target values.

The OnEfficiency.Strength principle: visualize, stabilize, optimizeOnEfficiency.Strength combines three modules to create a new, powerful generation of advanced process controls (APC). The control system includes virtual sensors, also called soft sensors; model predictive control (MPC); and a cost optimizer. A special feature of the virtual and self-adaptive sensors is their high predictive accuracy, typically above 90 percent.

The virtual sensors precisely predict important quality parameters. Knowing these parameters in real time enables the MPC to control the papermaking process in such a way that the targeted values are permanently achieved through continuous adjustment. The cost optimizer ensures that this is done at the lowest possible cost. To find the customer-specific cost optimum, actuators and control strategies can be individually selected and flexibly adapted.

Laakirchen Papier AG was particularly impressed with the high savings potential offered by OnEfficiency.Strength. This was calculated in the Value-Add Assessment carried out in advance. "Before installation, we carry out a so-called Value-Add Assessment with our customers, in which we calculate the savings potential of OnEfficiency.Strength based on the individual customer data," says Dr. Julius Flitsch, head of the Voith OnPerformance.Lab. "We then guarantee this savings potential to our customer. In addition, we always determine the parameters and actuators to be controlled individually, depending on customer requirements and paper machine."

Laakirchen Papier AG and Voith: Lighthouse project in Papermaking 4.0Laakirchen Papier and Voith have been working on joint pilot projects in Papermaking 4.0 since 2019. "We’ve had very good experience working with Voith. In addition to the OnEfficiency.Strength project, we also have many other Papermaking 4.0 pilot projects being implemented at the site. These include OnEfficiency.BreakProtect, OnCumulus and most recently OnView.Energy. This enables us to continuously improve our papermaking process," says Jan Reibert, Production Manager PM 10 at Laakirchen Papier AG. "Our cooperation with Voith is always at a very high level and on an equal footing. During the OnEfficiency.Strength project phase, we were in close and intensive exchange. This enabled us to discuss potential challenges together, discuss appropriate solutions and implement them in a timely manner."

At the beginning of June, the XcelLine PM 6 supplied by Voith was successfully started up at the Jinzhong site in the central Chinese province of Shanxi by the paper manufacturer Shanxi Qiangwei Paper. As the leading full-line supplier, Voith delivered the entire production line. The machine has a wire width of 7 m, a design speed of 1,200 m/min and produces plasterboard liner and containerboard with a basis weight of 90 to 160 gsm. Annual production of over 300,000 tons is possible. Voith's latest solutions enable highly efficient, resource-saving and sustainable production.

  • The XcelLine paper machine supplied by Voith was successfully started up at the Jinzhong Shanxi Qiangwei Paper´s site
  • The new PM 6 will produce over 300,000 tons of plasterboard liner and containerboard per year at a design speed of 1,200 m/min
  • Leading Voith technologies enable highly efficient and optimized production

Thanks to the joint efforts and cooperation of the Voith and Shanxi Qiangwei Paper teams, a fast installation and start-up of the entire line was achieved. The PM 6 has a high degree of automation, and the paper features a low tensile ratio, excellent surface quality and uniformity, as well as high breaking and folding strength. The dryness after the press is also very high, which leads to low specific steam consumption. The first paper web has thus fully achieved the customer´s expected quality level.

Latest technologies for optimum results
As the leading full-line supplier, Voith supplied the entire XcelLine paper machine. The customer-oriented concept is especially designed for maximum efficiency, robustness and sustainability. After Voith had cooperated very successfully with Shanxi Qiangwei Paper on the key equipment for PM 5, the papermaker had ordered the supply of the entire PM 6 from Voith. Voith's advanced technologies and concepts will help Shanxi Qiangwei Paper to secure its leading position in the plasterboard industry and further expand its market share in the packaging paper industry. Thus, a positive contribution can be made to the development of the surrounding region and the economy of Shanxi.

The full-line supplier Voith delivered two highly efficient MasterJet Pro headboxes, a Tandem NipcoFlex press section and a CombiDuoRun dryer section including a hood and machine air system. Optimum paper properties are ensured by a SpeedSizer AT and an EcoCal Hard calender. The reliable MasterReel reeling concept, including a parent roll handling system and discfilters for fiber recovery, is used for smooth production. Shanxi Qiangwei also relies on the latest automation solutions from the Voith Papermaking 4.0 portfolio to achieve additional efficiency increases and cost reductions. A control and information system (DCS) as well as the quality management system (QCS) OnQuality are integrated in the plant.

Successful cooperation between Voith and Shanxi Qiangwei
To ensure a smooth start-up of the paper machine, both sides worked closely together throughout the project. Lin Jiangbo, Vice President Order Execution at Voith Paper Asia, confirms: "With the challenges posed by the recent COVID-19 pandemic, Voith worked with a high degree of flexibility and in close cooperation with Shanxi Qiangwei to ensure an optimal start-up of PM 6. In the future, we will continue to provide comprehensive services for PM 6 throughout its life cycle with our technical expertise and take further steps together with Shanxi Qiangwei Paper."

OnQuality.Scanners and OnQuality.Sensors are successfully used in over 750 installations worldwide to continuously improve production and quality processes. Thanks to their compact design, the scanners can be installed extremely flexibly in existing and new plants. Based on the leading solutions, Voith now presents OnQuality 4.0, the next level for digitalization of the paper mill. The new system consists of all the important elements required for perfect quality measurement and control: a secure cloud solution with many analysis tools and functions, virtual sensors for online and real-time measurement, as well as location- and time-independent technology consulting. The OnQuality 4.0 system can be upgraded modularly for all Voith OnQuality systems already installed and is ready for use within a very short time.

  • OnQuality 4.0 increases data transparency, enhances quality measurements, optimizes control strategies and thus leads to significant cost savings
  • Analyses, dashboards and reports can be created with a few clicks and accessed on smartphones and tablets
  • Latest generation of virtual sensors complement the classic physical sensor portfolio and provide new possibilities in online quality measurement

"With OnQuality 4.0, we are introducing the most advanced quality measurement and quality control system currently available for manufacturers of all paper grades," confirms Marc Stampfer, Global Product Manager QCS Scanners & Sensors at Voith Paper. "Time-consuming collection, search and conclusion of quality data and control strategies are a thing of the past. With our intuitive cloud solution, virtual sensors as well as remote technology consulting, the foundation for the digitalization of your paper mill is laid."

Perfect interaction between cloud solution, sensors and technology consulting
OnQuality 4.0 uses virtual sensors to overcome the limitations of classic physical online sensor technology. Using artificial intelligence, the virtual sensors continuously, reliably and in real time predict quality parameters such as tensile strength, stiffness and softness that can otherwise only be measured in the laboratory. The cloud platform collects and stores all relevant production and quality data and enables users to perform in-depth analyses through personalized dashboards. With just a few clicks, profile charts, color maps, maintenance cockpits, trends and reports can be intuitively created and viewed on mobile devices. OnQuality 4.0 thus quickly and directly shows deviations from the critical target quality and enables significant savings in resources, scrap and costs.

The OnPerformance.Lab (OPL) remote service center completes OnQuality 4.0, with OPL experts providing round-the-clock support for real-time emergencies. With the help of the in-depth know-how in the field of paper and control technology, tailor-made optimization measures are carried out together with the customer, such as for MD and CD controls and grade change processes. Consequently, the efficiency of the machine increases while costs decrease.

Further optimizations are planned for the future. Voith is currently working on visionary OnQuality.Scanner concepts, which are being developed as part of the Papermaking Vision design study. "With intuitive and state-of-the-art operating and visualization interfaces directly on the scanners; an intelligent light and alarm system; and an attractive, maintenance-friendly design, we will once again make everyday work much easier for operating and maintenance personnel," sums up Marc Stampfer.
