Quality control upgrade for SCA Ortviken

S

CA’s Ortviken paper mill in Sweden is having the quality control system on its LWC4 paper

making line upgraded by power and automati on group ABB. The project scope includes a number of new functi ons and measurement scanners for the paper quality control process as well as integrati on of the new functi ons in the existi ng operator environment. The upgrading project represents the fi nal step of integrati ng the enti re control in one single operator environment in the paper line. The System 800xA QCS quality

control system with six operator stati ons will be integrated in a ‘virtualised’ server as well as in the existi ng operator environment for DCS and drive systems. SCA Ortviken is one of the

fi rst paper mills to use ABB’s technology for virtual operator

stati ons, which off ers benefi ts that include lower system maintenance and energy use since fewer hardware units are needed to do the work that previously required one computer for each operator. The order also includes

the replacement of older measurement scanners with the Network Platf orm including the latest technology such as a HPIR moisture measurements meter and an Opti cal Caliper thickness meter. Multi variable CD Control (MCD) is used for profi le control, which enables control decisions based on the most important paper quality aspects in every situati on. The new system will be commissioned in late May 2013. SCA Ortviken is one of the

largest paper mills in Sweden with four paper machines and a yearly output of 510,000 tons LWC and 380,000 tonnes of un-coated paper.

the machine investment in line with the mill’s capacity needs and ensures opti mised producti vity at minimal operati onal cost,” said Sami Antti lainen, R&D director of paper business line at Metso. The design of the line enables

easy and safe changing of rolls and wear parts, reducing service costs and maintenance shutdowns. A spacious walkway on the drive

side of the machine improves accessibility and safety. The project comprises a

Opti Concept M boardmaking line from headbox to reel with related air systems. A comprehensive automati on package comprises a mill-wide Metso DNA automati on soluti on with machine and process controls, a Metso IQ quality control system and a Metso IQ Diluti on Profi ler. The 7.25m-wide (wire) line will

produce testliner grades in the basis weight range of 70-160 g/m2 from recycled raw material.
