High Speed F Flute Tungsten Carbide Corrugating Roll for BHS Corrugator Machine
1. Strict Selection of Tungsten Carbide Corrugating Rolls Material
The best manufactuer of 50CrMo alloy steel in China supply us raw material. Barrel thickness is more than 70mm. Adequate raw material in warehouse can guarantee the delivery time for our tungsten carbide corrugating rolls.
2. Precision Welding Make Inseparable
The roll barrel and shafts shrink fit together. After welding do tempering to reduce stress. We do steam leak detction too.
3. Flute profile
The most important parameter is the flute profile. To design the flute profile, we must know the corrugated paper gsm, speed, flute height, correct diameter and other requirement such as good FCT, saving paper, etc. Our engineer has rich experience of designing flute profile. Without good design, many problems will appear, such as flute paper broken, low speed, collapsed flute, high-low flute and so on.
The following table is just for a reference.
| 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 |
