What are the advantages of thermal spraying processing rollers

The TAD Paper Machine (Through Air Dried Paper Machine) has become an important equipment in the modern papermaking industry with its unique drying method and efficient production capacity. However, the wear and corrosion problems of traditional rollers have long been plaguing production efficiency and product quality. The application of tungsten carbide coated rollers in TAD paper machines through supersonic spraying technology has significantly improved this situation. What advantages do the rollers after thermal spraying have in TAD paper machines?

The high hardness and wear resistance of the tungsten carbide coating enable the rollers to effectively resist wear during long-term operation and extend their service life.

The anti-corrosion performance of the coating significantly reduces the corrosion risk of the rollers in a humid environment, ensuring the stability and reliability of the equipment

In addition, the application of supersonic spraying technology has also enhanced the adhesion of the coating and improved the overall performance of the rollers.

Unlike the ideal conditions in the laboratory, there are more variables on the actual production line. We collected the three-year operation data of the customer's paper machine and simulated the accelerated aging test under the most severe working conditions. The project leader said. This scene-driven R&D model ensures the precise alignment of technical solutions with production demands.

In terms of operating costs, the service life of the roller body has been extended from 6-8 months to over 2 years, reducing the frequency of downtime and replacement. The annual production increase is approximately 1,200 hours, and maintenance costs have been reduced by more than 60%. In terms of product quality, the uniformity of the paper surface has been improved. The dust level has been reduced by 30%, eliminating paper defects caused by roller surface wear. The rate of top-quality products has increased to 99.2%. In terms of sustainable development, it replaces the traditional chromium electroplating process, eliminates hexavalent chromium pollution, and the coating can be repeatedly repaired, achieving resource recycling. The energy consumption per unit of production capacity has been reduced by 15% to 16%.

The successful application of thermal spraying technology on the first TAD paper machine roller not only brings a new solution for wear resistance and corrosion resistance to the papermaking industry, but also lays a foundation for future technological innovation. With the promotion of this technology, it is expected to further drive the sustainable development of the papermaking industry.
