Reliability
-
Securing mill efficiency and continuous reliability improvement
Most equipment failures are random. For high value, critical equipment this program proactively does the right work at the right time and maximizes reliability.
-
Optimize operations with a Roll Cover and Maintenance Agreement
Sending rolls to multiple suppliers can be expensive, cause a loss in continuity and create extra burdens for roll management. A roll agreement will help.
-
Optimize doctoring performance and lower total cost of ownership
Every doctoring process can be improved. The usual investments required are minimal. Optimizing your doctoring processes results in better runnability, improved quality, optimal production efficiency, reduced maintenance costs and improved safety and environmental effect.
-
Avoid the wrinkles and web breaks that result from poor splicing
Splicing offers little reward for a job well done, but big penalties to the bottom line for poor quality workmanship such as when customers return shipments.
-
Avoid winder vibration with modern software and hardware tools
Some paper grades generate winder vibration. Modern tools help, such as 4-way hydraulic valves, stiffer drums with lower dynamic runout and automated controls.
-
Proper bearing lubrication and modernization are essential
Most bearing failures can be traced to two maintenance oversights: a lack of lubrication or the use of the wrong type of lubrication. An upgrade may be needed.
-
Balancing rolls - balance and imbalance, isolating the problem
Unbalanced rolls hammer at the framework of the papermachine, leading to worn journals, bearings and covers. Balancing rolls lengthens component lifetimes.
-
Larger jumbo rolls increase pressroom breaks, a case study
Larger wound roll sizes dramatically increased press breaks for an LWC mill's customer. Process analysis and Valmet small fixes provided a temporary solution.
-
Solutions to multiple poly roll cover failures, a case study
After blowing two expensive roll covers, a mill asked Valmet to investigate. After checking roll history, nip impressions and coolant, the culprit was an inexpensive part.
