The Yankee dryer is the heart of a tissue machine. It needs to retain a stable surface for creping, withstand high loads of creping and cleaning blades, and cope with occasional dry running situations. Optimized thermal sprayed coatings, often referred to as Yankee metallization, are compatible with the organic Yankee coating and resistant to chatter. These coatings provide creping stability with ceramic-tipped blades and allow trouble free operation that is demanded by tissue producers. State-of-the-art electric arc wire spray equipment allows our customers to operate with reliability and achieve top-notch results for time-critical, on-site coating projects.
No Chatter is What Matters
High-quality thermal spray coatings on a Yankee dryer protects the tissue mill’s assets by prolonging the cast iron Yankee life significantly. A coating lifetime of over 10 years in operation is achievable, while a Yankee without a coating would need a regrind every couple of years. A thermal spray coating can also be reapplied, when required, with almost no loss of material thickness on the Yankee shell. This makes thermal spray a perfect solution for steel Yankees as well.
Oerlikon Metco’s spray equipment and a full range of materials for consistent on-site spraying is the ideal solution for high-performance Yankee dryer coatings. Our proven SmartArc™ arc spray technology provides the quality, stability and consistency needed for coatings in these challenging on-site environments.
