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.
