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 |
3.Precision Index of B Flute Corrugated Roller
| Item | Index |
| Gear teeth height limits of deviation | ≤ 0.01mm |
| Addendum circle run out tolerance | ≤ 0.02mm |
| Gear teeth width limits of deviations | ≤ 0.015mm |
| Tooth profile limits of deviations | ≤ 0.01mm |
| Gear lateral face counter shaft parallelism | ≤ 0.01mm |
| Tip cylinder element linear | ≤ 0.01mm |
| Gear teeth division limits of deviations | ±10" |
| Smooth finish | Ra<0.6µm |
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.
