Stora Enso Skoghall BM8 reduces grade change times by 25%
May 11, 2016
Replacing old quality control system (QCS) on Stora Enso Skoghall board machine KM 8 with a modern Valmet IQ system with three scanners, has cut the time of grade changes by 25%. KM 8 is the biggest liquid packaging board machine in the world, with a production capacity of 465,000 tonnes of five-ply board coated three times on the top side with a starch application on the wire side.
All three start-ups have been very successful and managed to achieve approved quality after just ninety minutes. We have now been running KM 8 for more than eighteen months with the complete Valmet QCS system. Almost all our goals have been achieved, including shortening run-in periods and quality change times by 25%.”
