Tungsten Carbide Super Hard Traditional Corrugating Roll

Long lifetime Traditional Corrugating Roll Tungsten Carbide Rolls

1. Introduction

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.

2. 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.

3.Repeatedly Polished, Smooth As a Mirror

Meijia adopts special polishing crafts, such as the corrugated rollers use America Praxair 1342VM series super hard tungsten carbide roller, special customized polishing wheel. With our company’s fully automatic CNC corrugated roller producing process’s special polishing machine and our independent grinding polishing technology R&D, the tungsten carbide roller’ s surface finish degree can reach Ra<0.6μm, which will improve the accuracy of the flute profile, and make sure the quality of the corrugated roller.

5. 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.
