Fuli SFM25N Cassette Alloy Steel Corrugating Rolls For Single Face
Corrugated Cardboard Roll
Flute Profile
The designed parameter of flute is not in line with the
manufacturing parameters, and the smooth finish of the roll surface
is inadequate,causing a high tension of corrugating roll during the
running process,that made a poor meshing and resulting in fluting
paper broken.
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.

Clean alloy steel corrugating rolls well:
1. Don’t wash the corrugating rolls directly when the rolls are
hot.
2. After the corrugating rolls cool down, wash the rolls by water
or gas.
3. Clean the glue and paper scraps on corrugating rolls after
production to avoid scratches of coatings.
4. After cleaning, apply silicon oil on corrugating rolls.
Features:
1. Our medium frequency quenching machine makes the hardness >
HRC58. Heating treatment technology remove tension repeatedly to
reduce deformation.
2. CNC grinders are equipped with Siemens operation system to
guarantee precision.
3. Advanced American Praxair JP8000HVOF tungsten carbide plating
machine, Blasting machine and Polishing machine. High bonding
strength of tungsten carbide powder and international standard
polishing is our biggest advantage.
