Breaking the Cycle of Frequent Repairs: A New Approach to Auger Flight Durability

The Challenge

Auger flights experienced rapid wear and tear due to intense abrasion from pulp and wood chips, needing refurbishment every 7 to 10 months. This wear was due to the use of AR450 material and a competitor’s hardfacing on the front edge, leading to high maintenance costs.

The Solution

Our Wear Management Team introduced a cutting-edge solution that combines multiple technologies. By leveraging wear-mapping, we produced a new screw with CDP spiral engineered flights, tungsten carbide hardfacing on the shaft and edges, and a final encapsulation with a MeCaTeC polymer coating known for its resistance to high heat and extreme abrasion.

The Outcome

The new screw was installed without delay, boasting a service life extension from the usual 7-10 months to an impressive 24-28 months. This success has not only optimized output and part performance for our customer, but it has also contributed to sustainability efforts by reducing the carbon footprint.

CUSTOMER TESTIMONIAL:

“Castolin Eutectic’s CDP wear plate and its proprietary hardfacing overlay technology have performed beyond any other competitor’s products that we’ve tried in the past. The company introduced us to custom-engineered solutions that have exceeded the higher-than-expected life cycles within our mill.” Maintenance Planning Manager - Forest industry
