Customer: Sca
Production: Kraftliner
Supplier: Voith
Description: Voith and Sca partner to build a world-leading, innovative production line at the Obbola paper mill. The new paper machine will produce 725,000 tons of kraftliner per year. With a wire width of 10,200 mm and a design speed of 1,400 m/min, the PM 2 will be the most productive of its kind.
Details: As full-line supplier for the entire papermaking process, Voith follows the Process Line Package (PLP) concept approach and assumes comprehensive responsibility for the project, covering the BlueLine stock preparation system and XcelLine paper machine. The comprehensive product scope includes detailed engineering and the supply of all sub-systems and components for the process line. The PLP reduces the number of required interfaces and contact persons and simplifies the entire project handling.
Highlights of the OCC plant include the IntensaPulper, the industry benchmark for energy efficient pulping, and the maintenance free Bagless Disc Filters. The production line will enable industry benchmarks in kraftliner strength and convertibility to be achieved through a unique combination of proven components and intelligent controls. The multi-ply forming section with the DuoFormer Base and the MasterJet Pro headbox are tools for the online control of critical product quality criteria. The well-proven TripleNipcoFlex press section has been adapted for the production of kraftliner in order to achieve the highest production rates and surface quality levels. The CombiDuoRun dryer section, including EvoDry steel dryers and an intelligent S&C system, will ensure maximum runnability and energy efficiency. The VariFlex Performance winder incorporating SmoothRun technology will provide consistent quality rolls at maximum operational efficiency.
The scope of supply for SCA includes the biggest and most innovative package in Voith Paper history and sets a benchmark in digitalization. The Papermaking 4.0 technologies cover products of the OnEfficiency product family, which use machine learning to increase the efficiency of the plant. Furthermore, it stabilizes and improves product and process quality. The OnCare products – with monitoring applications as well as digital services like OnCall Video and the connectivity to the Voith Paper Webshop – complement the OnCumulus IIoT platform product portfolio and provide the foundation for a digital integration of the value chain and predictive maintenance. The new paper machine thereby benefits from the full digitalization scope.
Start-up: The start-up of the machine is scheduled for the first quarter of 2023.
