Customizable drying cylinder
TANMNG
The dryer cylinder is the core high-temperature drying component in the paper machine dryer section. It conducts uniform heat transfer to dewater, shape and dry wet paper webs, directly affecting paper smoothness, dryness, density and final product quality. It operates under harsh conditions of continuous high temperature, humidity alternation, water vapor corrosion and pulp adhesion.
Traditional cast iron and chrome-plated dryer cylinders suffer from rapid wear, rust pitting, pulp sticking, coating peeling, uneven heat conduction and frequent downtime maintenance. Jinan Tianmeng provides custom dryer cylinder solutions with HVOF supersonic spray and arc spray technology, customized with tungsten carbide and composite functional coatings according to actual working conditions. All coated cylinders are verified by on-site operation with stable performance and worldwide customer recognition.
Dual Process Customization (HVOF & Arc Spray): We select the optimal spraying process based on on-site temperature, speed, pulp quality and corrosion level. HVOF supersonic spray delivers ultra-dense, high-hardness, long-life coatings for high-end and high-speed lines. Arc spray provides cost-effective, thick and stable coating renovation for regular production and old cylinder repair.
Condition-based Coating Customization: Custom wear-resistant, anti-stick, anti-corrosion and high-temperature resistant coatings solve common problems such as surface abrasion, corrosion, paper sticking and uneven heat conduction.
Mirror Surface Finishing: High-precision polishing after spraying achieves super mirror effect, ensuring smooth paper release, no scratches and improved paper grade.
Spray Process & Coating Type | Key Performance | Applicable Working Conditions | Paper Types | Operation Effects |
|---|---|---|---|---|
HVOF Tungsten Carbide Coating (Premium) | Ultra-high hardness, dense structure, strong adhesion, anti-scour, high temperature oxidation resistance | High-speed lines, 24h continuous heavy-duty, high-precision drying requirements | High-grade cultural paper, specialty paper, high-speed tissue paper | No pulp sticking or corrosion, uniform heat conduction, 3–5 times longer service life than chrome plating, fewer downtimes |
HVOF Anti-stick Mirror Coating | Super smooth mirror finish, self-cleaning, perfect paper release, no pinholes | Thin paper, high-brightness paper, strict surface quality requirements | Thin paper, premium office paper, fine specialty paper | Eliminate paper sticking, scratches and stains, greatly improve finished paper yield |
Arc Spray Tungsten Carbide Composite Coating (Cost-effective) | Uniform thickness, strong adhesion, good wear resistance, high construction efficiency | Medium-low speed lines, regular working conditions, old cylinder renovation | Ordinary cultural paper, packaging paper, industrial paper | Effectively improve wear and minor corrosion issues, stable drying performance, low-cost equipment upgrade |
Arc Spray Anti-corrosion Coating | Waterproof, anti-rust, acid & alkali resistant, dense barrier against moisture | High humidity, dry-wet alternation, white water corrosive environment | All conventional paper types | Prevent rust, pitting and coating bulging, maintain stable performance in humid harsh conditions |
High-temperature Anti-oxidation Coating | Excellent thermal stability, anti-thermal aging, long-term high-temperature resistance | Long-term high-temperature drying and temperature fluctuation conditions | High-temperature shaped paper types | Keep coating stable under continuous heat, ensure uniform heat conduction and consistent paper quality |
All customized coated dryer cylinders support on-site trial operation and verification. With high surface flatness, uniform heat conduction and excellent anti-stick performance, our dryer cylinders effectively solve paper sticking, pulp accumulation, corrosion, uneven drying and frequent maintenance problems. Global customers confirm that tungsten carbide coated dryer cylinders have 3–5 times longer service life than traditional chrome-plated cylinders, significantly reducing downtime, maintenance costs and paper defects with high repurchase rates.
1. Paper sticking and pulp residue accumulationSolution: Apply HVOF mirror anti-stick coating for self-cleaning and smooth paper release.
2. Rust, pitting and coating peeling in humid environmentSolution: Adopt arc spray anti-corrosion + carbide composite protection to isolate corrosive media.
3. Fast surface wear and uneven dryingSolution: Use HVOF tungsten carbide wear-resistant coating for ultra-hard anti-scour protection.
4. Paper bubbling, wrinkling and poor shapingSolution: High-precision spraying and mirror polishing ensure full-cylinder uniform heat conduction.
5. High renovation cost and short service life of traditional chrome platingSolution: Upgrade with HVOF/arc thermal spray technology for strong adhesion and long-term durability.
We provide one-stop export solutions including working condition analysis, HVOF & arc spray process selection, custom coating design, precision construction, mirror finishing, quality inspection and global delivery. OEM & ODM orders are available. Professional English technical documents and inspection reports support international procurement.

The following are some main advantages:
1. Enhance wear resistance: Thermal spraying can use wear-resistant materials such as nickel-based alloys and tungsten carbide to form a solid coating on the surface of the drying cylinder, significantly improving its wear resistance, reducing surface wear caused by long-term operation, and extending the service life of the drying cylinder.
2. Enhance corrosion resistance: In the papermaking industry, acidic and alkaline media, steam and water vapor can cause corrosion to the drying cylinders. However, by applying a layer of corrosion-resistant materials such as stainless steel or nickel-based alloys through thermal spraying, the corrosive media can be effectively isolated, protecting the drying cylinders from erosion.
3. Improve thermal conductivity: By using materials with good thermal conductivity, such as aluminum and copper, for thermal spraying, the heat transfer efficiency of the drying cylinder can be enhanced, the drying speed of paper can be accelerated, and productivity can be increased.
4. Repair and Renovation: For old or slightly damaged drying cylinders, thermal spraying technology can be used for local or overall repair, restoring dimensional accuracy and flatness, saving the cost of replacing new drying cylinders, and achieving effective utilization of resources.
