High Speed B flute Corrugated Roller TC Plating Corrugated Industry
Application:
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.
Tungsten carbide corrugating roll is the most important part of single facer and it’s a essential part for corrugated cardboard or carton manufacturers. We apply JP8000 HVOF technology which is imported from American Praxair. High hardness, strong binding force, good abradability and excellent performance of polishing can prolong the service lifetime.
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.
Problem↓↓
The insufficient precision of corrugating roll and unstable materials lead to the flute teeth deforming during the running process, which can cause bad meshing and unstable operation,and resonance will be occurred while critical value being reached.This is how high-low flute being caused in corrugated board.
Solution↓↓
The unique way of ultra-high pre-expansion is adopted to deal with the high temperature and pressure inside the corrugating roll,and improve the capacity of anti-fatigue strength and elastic strength,enabling corrugating roll to avoid deformation and uneven expansion during the following use.It has perfectly solved the problem like resonance(the main reason why collapsed flute and high-low flutes happened),which caused by deformation,unstable texture,uneven expansion during running process.
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.
