Chinese tissue and board producers Wuhu Hengan Paper Co. and Shandong Sun Paper Industry Joint Stock Co. have placed several orders for Metso's automation solutions to boost their processes and improve product quality. Wuhu Hengan has chosen the Metso DNA automation system, the Metso IQ quality control system, and non-radiation IQ Fiber Weight Measurement technology for new tissue lines at its greenfield tissue mill.
Metso IQ is a quality control systems (QCS) approach that integrates process quality management, measurements, and profile controls with profilers to provide operating personnel with what they need to understand and manage the process.
Shandong Sun Paper has placed an order for two Metso Wet End Analyzers (Metso WEM) for its new production lines. These analyzers combine all of the relevant wet end variables as a total solution for wet end management. To meet the objectives set for quality, runnability, and overall efficiency, it is vital to stabilize consistency, ash content, charge. and chemistry at startups, during normal operation, and after grade changes. It is best done by measuring, analyzing, controlling, and managing the wet end as comprehensively as possible with cutting-edge analyzer technology, Metso explains.
"Today, more and more chemicals are used in the tissue production process. It is necessary to measure online the most suitable chemical environment for the process," ZhongDe Ye, VP, Sales & Service, Great China, Automation, Metso, points out. "The customer already has several Metso charge analyzers on another paper machine, so they know the analyzers' real performance and how this benefits the process."
Additionally, Metso has received an order for Metso IQ quality control technology to be supplied to a Chinese coated board production line. The line will be rebuilt to produce high-quality folding boxboard. Metso's delivery will include a Metso IQ Scanner with MD and CD controls to provide fast, high-resolution sheet quality profiles from edge to edge. A Metso IQ Dilution Profiler (IQ Dilution Profiler), a profile control system for advanced positioning of the headbox valves, also will be supplied to achieve the best possible weight profiles.
