High Speed 250m/min Tungsten Carbide B Flute Corrugated Roller
Cardboard Making Machine
1. Features of Tungsten Carbide Corrugating Roll
a. Tungsten carbide corrugated roller has excellent wear resistance
and low flute height. Moreover, it will not reduce the compressive
strength of the finished corrugated board.
b. A more optimized v-shape flute profile can be designed to
increase the strength of the cardboard, reduce the amount of the
glue applied and save corrugated paper.
c. The service life of tungsten carbide corrugated roller can reach
at least 40 million meters, reducing the number of maintenance and
replacement times, saving manpower, material and financial
resources.
d. Tungsten carbide roller’s wear resistance is good, and it’s
tungsten carbide coating adopts special removing process, so
corrugated roller substrate can not be damaged, and corrugated
roller can be used for many times with repairing.
2. Flute Profile
Almost every set of corrugating rolls are needed to be designed and
customized separately according to the width, diameter, flute
height, corrugated paper GSM, speed and cardboard physical index
requirement.
| Flute | Profile | Height(mm) | Pitch(mm) | Flutes/300mm | T.U.R |
| A | UV | 4.5-5.0 | 8.0-9.5 | 34±3 | 1.45-1.52 |
| C | UV | 3.5-4.0 | 6.8-7.9 | 41±3 | 1.37-1.47 |
| B | UV | 2.5-3.0 | 5.5-6.5 | 50±4 | 1.33-1.41 |
| E | UV | 1.1-2.0 | 3.0-3.5 | 93±6 | 1.24-1.36 |
| F | UV | 0.8-1.0 | 2.2-3.2 | 115±20 | 1.19-1.25 |
| G | UV | 0.6-0.8 | 1.8-2.8 | 136±20 | 1.15-1.20 |
| N | UV | 0.4-0.6 | 1.2-2.2 | 193±55 | 1.10-1.15 |
| Others | UV | Customized | Design | Design | Design |

4. High Hardness from Vertical Quenching Process
Intermediate frequency quenching can guarantee both the hardness
and harden depth we need. Our harden layer depth can reach to
8-12mm. With harder base material as foundation, the lifetime of
our corrugating rolls are greatly extended. After different heat
treatment process, the corrugated roller surface becomes more
wear-resistant and durable. After heating treatment we cut slots of
lower roll though this process needs more time but makes uniform
hardness.
