Inner Suction A Flute Hard Chrome Corrugated Roller Steam Heating
Introduction:
--The largest professional corrugated roller manufacturer in
northern of China
--50CrMo refined forging steel supplied by the best manufacturer in
China.
--A, C, B, E, F, G, N flute corrugated rolls
--High Speed can reach to 200m/min
--Hard Chrome 0.06-0.08mm
--Medium frequency quenching heating treatment machine makes --the
hardness of base steel more than HRC58 and harden layer 8-12mm.
--High precision and high performance CNC grinding machine equipped
with Germany Siemens control system.
--We design the flute profile according to customer’s medium paper
GSM, speed, FCT requirement. The flute profile is more reasonable,
suitable to customer’s machine
--Our corrugated rollers has been exported to many countries such
as Korea, Russia, Egypt, India, Thailand, Myanmar, etc.
--Supply corrugated rollers for all kinds of corrugator line such
as Fosber, BHS, BW Paper System, K&H, HSIEH HSU,Fuli, Wanlian,
TCY, Champion, West River, Mingwei and so on.
1. Strict Selection High Quality Material
50CrMo alloy steel is specialized material for manufacturing
corrugating rolls. Our raw material shell thickness is more than
70mm, the thicker shell can reduce deformation and keep stability
during production.
2. 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 the welding process finished, the work piece
shall be put into the furnace for high temperature tempering to
reduce stress.
3.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.
.
4. Rigorous for Precise Grinding
After heat treatment and the cutting slots, the roller shall be put
on high precision automatic CNC grinding machine to do finish
grinding. By grinding wheel grind each flute several times until
the accuracy is within our technical permitted requirement. The
Siemens control system play a key role in guarantee the accuracy.
5. 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 |
6.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.
