B Flute Peripheral Heating Corrugating Roll
1.Precision Welding
Both sides of the roller body should be heated to drill the inner
hole. Then putting the spindle heads into the hole, the roller body
and the spindle heads should be held tightly after natural cooling.
2.High Hardness through 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.
3. Durable from Supersonic Tungsten Carbide Spraying
Spraying technology is the key point, which can ensure the hardness
and binding force of tungsten carbide.Most advanced Praxair JP 8000
HVOF tungsten carbide spraying equipment and technology is adopted
and Praxair 1342 super hard tungsten carbide powder is used for our
corrugating roll. Before tungsten carbide spraying, we do sand
blasting treatment on the surface which make rough surface to
increase adhesion of tungsten carbide powder.

4. Strict Test to make sure the high quality
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.
