Indian Single Facer Corrugated Hard Chrome Plated Roller G Flute
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 |

Precision Welding Can Be Inseparable
Both ends of the roller body should be heated to release the size
of the inner bored hole. After the spindle heads are put in, the
roller body and the spindle heads should be held tightly after
natural cooling. When everything is ready, a driving fit interface
has been formed between the roller body and the spindle heads by
means of preheating, welding or bolting. Special care should be
taken when welding, because finished corrugated roller body’s
temperature will rise constantly when the roller is running, and
the roller body also bears pressure of the steam from the inside of
the roller body, which will form the so-called “pressure vessel”.
In view of this, the roller body and the spindle heads joint must
pass the pressure test. When the welding process finished, the work
piece shall be put into the furnace for high temperature tempering
to reduce stress.
Strict Test to Keep Improving
Before and after the surface treatment including tungsten carbide
plating or hard chrome coating of corrugating rolls, it is needed
to check the size, hardness, precision, flute profile, and
simulation feeding paper. Special projector is used to check the
flute profile and feeding different GSM paper to ensure the
performance of corrugating rolls.
