A Valmet *-supplied OptiConcept M production line, PM 6, for Liansheng Paper Industry in China, was successfully started up on December 12, 2012.
On December 12, 2012, Liansheng Paper Industry (Longhai) Co., Ltd. started up their new containerboard production line, PM 6, at their Longhai site in Fujian Province, China. This is the first start-up of Valmet’s novel OptiConcept M production line, representing a new way to design, build and operate a paper machine.
The PM 6 start-up set records right from the outset. “The whole start-up was perfect. After stock was first fed into the machine, it took fewer than three hours to get the web on the reel, and we had a very good start-up speed of 800 m/min. No paper tails were seen on the hall floor during the startup period,” proudly reports Xue Rong Jun, Project Manager of Fujian Liansheng.
The PM 6 OptiConcept M line is designed for high productivity at low operating cost. Its innovative industrial design and engineering facilitate assembly of the production line. “The installation required 30 to 40% fewer working hours than a conventional project,” comments Xue Rong Jun.

Usability and safety are also at a new level. For instance, the design allows for easy, fast and safe changing of wear parts, which reduces the duration and cost of maintenance shutdowns. “The design of the walkways is very ergonomic and spacious. They are on one level, with no need to run up and down stairs, so the machine is very safe and convenient to operate and maintain. Since there are no cantilevering beams at the wet end, the drive and tending sides are symmetrical, and the machine drive side is much more spacious than it is in a traditional machine construction,” says Xue Rong Jun. Valmet’s delivery included a complete OptiConcept M boardmaking line from headbox to reel, with air systems, a machine control system, a quality control system, two winders and Valmet clothing.
The new 7.25-m-wide production line has an annual production capacity of approximately 300,000 tonnes of recycled fluting in the basis weight range of 65 to 100 g/m2. The design speed is 1,200 m/min.
Liansheng Paper Industry (Longhai) Co., Ltd. is a subsidiary of Fujian Liansheng Paper Co., Ltd. The company was founded in 1999 and is based in Zhangzhou, China. PM 6 is the third Valmet-supplied production line for Fujian Liansheng.
