Metso supplied NSI Saugbrugs PM 6 starts up in record time

Norske Skogindustrier ASA has successfully started up the rebuild of Saugbrugs PM 6 SC paper machine in Halden, Norway. The machine, which was originally supplied by Valmet in 1993, produces annually some 300,000 tons of SC-A and SC-A+ rotogravure grades.

The Metso supplied paper machine rebuild came on stream on 19 March 2007. The start-up went smoothly and ahead of schedule. The paper quality has well fulfilled quality expectations of the rebuild, and printing results are expected to be on an equally good level.

The PM 6 SC paper machine was modernized with the latest headbox and forming technology. The rebuild included an upgrade of the existing headbox to an OptiFlo II headbox and the SpeedFormer section to an OptiFormer section with loadable blades.

Saugbrugs PM 6 papermaking line was also supplied with Metso's leading-edge finishing technology. Winder no. 6-1, the wrapping machine and conveyors were upgraded to handle super jumbo rolls up to 4,320 mm in width and 8 tons in weight. The Super Heavy Duty winding station and compliant winding drums improve roll hardness and quality of jumbo rolls. Winder no. 6-2 was rebuilt with compliant winding drums to maintain the same roll quality on both winders.

Additionally, the Metso supplied modernization of TMP2 thermo mechanical pulp plant at Saugbrugs was successfully started up. A Metso Double Disc 68 RGP refiner was installed into one of the two production lines. Also new pressure screening was supplied. A similar upgrade of the second production line in the TMP2 plant will be carried out during autumn 2007.

Metso is a global engineering and technology corporation with net sales of approximately EUR 5 billion. Its 25,500 employees in more than 50 countries serve customers in the pulp and paper industry, rock and minerals processing, the energy industry and selected other industries. www.metso.com
