Tungsten Carbide B flute Corrugated Roller Wanlian Corrugated
Cardboard Making Machine
1. Features of Tungsten Carbide Corrugating Roll
a. Tungsten carbide corrugated roller has excellent wear resistance
and low flute height. Moreover, it will not reduce the compressive
strength of the finished corrugated board. A more optimized v-shape
flute profile can be designed to increase the strength of the
cardboard, reduce the amount of the glue applied and save
corrugated paper.
b. Tungsten carbide corrugated roller will never wear in theory,
and can ensure the production of high quality finished corrugated
board’s durability
c. The service life of tungsten carbide corrugated roller can reach
at least 35 million meters, reducing the number of maintenance and
replacement times, saving manpower, material and financial
resources.
d. Tungsten carbide roller’s wear resistance is good, and it’s
tungsten carbide coating adopts special removing process, so
corrugated roller substrate can not be damaged, and corrugated
roller can be used for many times with repairing.
2. Advantages
☆ The domestic first-class technology and core operating team, each
member has rich experience with processing more than 5000 sets of
corrugated roller. Depending on the mature stable Taiwan craft
technology and the advanced international technology, we offer the
optimized design of corrugating roll flute profile totally
according to costumer’s requirement.
☆ The CNC intermediate frequency heat treatment quenching machine
adopts the foreign corrugating roll quenching technology and makes
the hardness of the substrate reach more than HRC58 degrees,
meanwhile it retains the toughness and maximizes the anti-thermal
deformation of substrate to ensure the stability of corrugating
rolls.
☆ The leading domestic high precision and high performance CNC
corrugating roll precision grinders, lathe, planer, and other
equipment are equipped with Germany's Siemens control system,
increase grinding accuracy in the maximum.
☆ With the mature of tungsten carbide plating technology, the most
advanced tungsten carbide coating equipment Praxair JP8000 , as
well as high quality imported Praxair tungsten carbide powder, the
abrasion performance of corrugating roll is extreme and maximize
the extension of the service life of the corrugating roll.
Intermediate frequency quenching machine.
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.
