Industrial Internet and agreements provide value, case studies

The combination of industrial internet and performance service agreements have benefited several mills worldwide, adding value to their operations. This article provides a glimpse at two such mills, and includes a link to Valmet's archived webinar which featured the industrial internet and remote solutions.

Hirun Web Stabilizer boosts efficiency at board mill, case study

In its continuing quest for better productivity and cost savings, Hamburger Hungaria chose Valmet Hirun Web Stabilizer blow boxes. Learn how the passive drilled bottom rolls improved runnability.

Simplifying vintage recovery boiler operation and maintenance

Old recovery boilers can be simplified by using the Valmet Spout System. Improve shattering and density, operate easier, increase safety and reduce maintenance.

Introduction to the tail threading process, efficiency and audits

If you can't thread the machine, production stops. Depending on the automation level of your machine, threading can be a safety issue. Achieving and maintaining tail threading efficiency is thus exceedingly important for safety and bottom line performance on machines making any grade of paper, board, pulp or tissue.

Winding principles part 2 - effect and elements of nip pressure

The relationship between rider roll pressure and shipping roll hardness is neither simple nor direct. This second article in the Winding Principles series explores the interrelationship between rider roll pressure, relief pressure, roll weight and nip load.

Mill Safety - Lockout procedures save lives and equipment

Locking out power sources and drives is an important safety procedure. If not done, components can be started while personnel are out of the operator's sight.

Reel primary arm nip relief methods reduce bottom waste at turnup

Excessive bottom waste occurs during turn-ups where there is insufficient primary arm nip relief at the reel. To avoid this, primary arm nip force control should start before turn-up and continue smoothly as the building parent reel travels down along the reel drum to the secondary arms at the kickout rails.

Winding principles part 3 - drum torque control methods, summary

When web tension and drum nip pressure are constant, drum torque will assure uniform or diminishing roll hardness from the core toward the outside of the rolls.
