1. Strict Selection of Corrugated Roller Material
With high strength and toughness, good hardenability, no obvious
temper brittleness, 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.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. Some manufacturers groove their lower
rollers before the rollers’ were harden, because it is relatively
easy to work with soft materials. By this could cause problems in
the later heating process for the rollers, which will make the
hardness of the rollers change. After heating treatment we cut
slots of lower roll though this process needs more time but makes
uniform hardness.

3.Durable from Supersonic Tungsten Carbide Spraying
Tungsten carbide corrugated roller producing technology is
different traditional corrugated roll. Because of the particularity
of tungsten carbide material, the requirement of the base material
hardness is higher, flute profile before tungsten carbide spraying
is more precise, which is needed to match the performance of
tungsten carbide. Spraying technology is the key, 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.
