Valmet has received a contract from Stora Enso to provide Valmet IQ Process and Quality Vision system (PQV) for the Sunila Mill in Kotka, Finland.
Under the contract, Valmet will supply Stora Enso Sunila Mill with a PQV system featuring a Valmet IQ Web Inspection System (WIS), which comprises a high-definition matrix camera system and a matching light source to capture crystal clear images of defects in the sheet.
Valmet automation on-line quality management solutions product manager Jukka Paananen said: "This solution features excellent dirt count calculation thanks to its highly advanced defect analysis methods that allow constant, real-time detection of small dirt specks and shives on a fast moving web in the pulp drying processes."
The PQV system, which will be installed on the pulp drying machine after the drying section, is expected to provide efficient and continuous online quality control for the mill.
Planned to be commissioned in November 2016, the new system is designed to monitor dirt and shives on the mill's pulp drying line 6 while optimizing both end product quality and line efficiency.
Stora Enso Sunila fiber line operations manager Henrik Antila said: "The results reached with the traditional dirt count method on a light table and the PQV correlate well. Additionally, we now have access to real-time dirt count data in the control room without any delay, and this helps us to control our process faster and more precisely than before.”
Valmet said it has earlier supplied similar PQV system for the mill's pulp drying line 4 in 2015.
