2500mm×Φ295/346mm 50CrMo alloy steel corrugated roller
Tungsten Carbide Coated Roll
1. Hardness and wear resistance are second only to diamond.
The service life is 3-5 times that of the chrome-plated corrugated roller.
Change time and cost reduced by 65-80% (including downtime and change costs)
Can be refurbished more times (not replaced)
Reduce the cost of corrugated paper per square meter
Avoid depreciation of related parts due to the concave surface of corrugated rollers (such as rubber rollers, squeegee rollers, pressure rollers, etc.).
2. The quality of corrugated cardboard is consistent
With excellent abrasion resistance, the groove height loss is between 0.06-0.08mm each time it is used. At the same time, as the top of the corrugated paper wears, the pattern of the corrugated paper will not be deformed, and the amount of glue will not increase. Therefore, it minimizes the amount of waste in the cardboard production process and ensures the uniform quality of corrugated cardboard.
3. Reduce the raw material cost of corrugated board
Because tungsten carbide corrugated paper has super abrasion resistance, its groove height loss is minimized, and paper consumption is reduced by more than 1% compared with chrome corrugated paper.
The top of the corrugated paper has less abrasion, which can reduce the slurry consumption cost by 20% to 50% and keep the thickness of the slurry layer uniform.
Avoid the quality restriction of ordinary cardboard and reduce waste loss by 30-50%.

Advanced technology of ultra-friction-reducing tungsten carbide coated corrugated roller
1. The most advanced equipment in the world
We introduce the most advanced thermal spray system JP8000 HP/HVOF, which is called the perfect "next generation" by Praxair TAFA in the United States, equipped with the 8100 CORONA air/fuel management system, which is closed-loop controlled by a PC. It has a high-precision control system to ensure flame performance and coating repeatability, so unique coating quality can be achieved.
2. Apply modern high-tech coatings
Cobalt-coated tungsten carbide (WC-Co) powder specially used for corrugating rolls manufactured by the world's top suppliers
3. Advanced professional thermal spraying technology
We strive to make our cobalt-coated tungsten carbide coatings have higher hardness, density and anti-friction properties.
4. Advanced polishing technology
The coating is polished with diamond to form a smooth surface coating with a small friction coefficient.
