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.

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.
