Voith supplied PM 7 to Hamburger Hungária in Dunaújváros, Hungary breaks records already at start-up

HEIDENHEIM, Germany, July 3, 2009 (Press Release) - Fast and perfectly on schedule, Dunaujvaros PM 7 started paper production in mid-June 2009. The packaging paper machine delivered by Voith produced the very first paper of 90 g/m² with a record speed of 1,225 m/min. The owner, Hamburger Hungária Kft. Containerboard, is part of the Austrian Hamburger Group and operates Hungary's largest paper mill at the Dunaujvaros site.

The PM 7, with a wire width of 8,600 mm, has been designed for a speed of 1,500 m/min. With an annual capacity of around 400,000 tons, the machine produces corrugating medium and testliner in a basis weight range of 70-150 g/m².

The entire production line, from stock preparation to reel, has been completed, using the proven One Platform Concept.

The PM 7 runs on a 100% recycled stock basis. Deliveries for the stock preparation line incorporated continuous disperging complete with the feeding unit and the reject handling system. Subsequent process phases include the protector system, fractionation, an EcoMizer cleaning system, hole and fine screening, and sludge treatment. The Voith components in the approach flow process include, among others, pulpers and sorters.

The DuoFormer Base gap former is equipped with a MasterJet M2 two-layer headbox with ModuleJet dilution water control. In the press section, a DuoCentri-NipcoFlex press with QualiFlex press sleeves guarantees high dry contents.

The entire dryer section is of single-tier design; solely the last group is double-tier. The SpeedSizer AT film coating unit provides uniform application on both sides.

The MasterReel ensures optimum winding quality of the 7,900 mm wide web, permitting maximum roll diameters of 4,000 mm.

The Voith deliveries also included an extensive automation package. OnControl MCS and DCS build a standard platform together with OnQuality quality control system and OnView information system. OnQuality, for instance, determines the quality parameters in machine and cross-machine directions. The OnView system provides complete information (product, process and machine data) about the paper production line from stock preparation to reel.

In addition, the corresponding field services have been part of the Voith scope of supply and will continue after the start-up of PM 7.
