Iggesund Paperboard Starts Rebuilt Board Machine at Workington Mill

Andritz, Austria, has successfully completed the board machine rebuild at the Iggesund mill in Workington, England. The new, state-of-the-art press section delivered by Andritz will increase the annual production capacity by 20,000 metric tons, reaching 220,000 metric tpy, and will further enhance the product quality and runnability of the board machine at the same time. Energy consumption has also been reduced by almost 10%.

Andritz has delivered a turnkey solution including basic and detailed engineering—a complete new press section with three presses: a jumbo press (LNP) with large-diameter rolls, a PrimePress X shoe press in the second nip, as well as a smoothing press. The new PrimeFeeder for ropeless tail threading from press section to dryer section is a state-of-the-art vacuum tail threading system that reduces the threading time and makes the threading process safer for the operators due to its remote control function.

The scope of supply also includes a new FibreSolve FSU under-the-machine pulper, field instrumentation, PrimeControl machine control systems, multi-motor drive integration into the existing drive system for 13 motors, the motor control center (MCC), electrification, and new wire section drives and press section drives. Full erection services, including supervision, commissioning, startup, and optimization after startup, were also performed by Andritz.

"Looking back, this was a super job by both our own staff and the contractors involved," said Ulf Löfgren, managing director of the Workington mill. "They worked day and night to give us the best possible results."

Roland Scheiflinger, VP, paper and board at Andritz, noted that "we are very pleased that we have been able to complete this important project for Iggesund Paperboard to the full satisfaction of our customer. The very good cooperation between Iggesund and Andritz made it a big success. We are very proud of this project."
