HSIEH HSU High Speed C Flute Corrugated Roller Tungsten Carbide

Corrugating roll is one of the most important components in corrugated carton production. Usually, it is an essential part of single facer. Corrugating rolls consist of two parts: upper roll and lower roll. The lower corrugating roll is the driving roll, which is generally fixed while the upper one is the driven roll.

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.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.

4. 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.
