High Speed 300m/min Peripheral Heating Corrugating Roll Tungsten Carbide Spraying
1.Precision Welding Make Inseparable
Both ends of the roller body should be heated to release the size of the inner bored hole. After the spindle heads are put in, the roller body and the spindle heads should be held tightly after natural cooling.
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.
3. Durable from Supersonic Tungsten Carbide Spraying
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. Strict Test to Keep Improving
Before and after the surface treatment including tungsten carbide plating or hard chrome coating of corrugating rolls, it is needed to check the size, hardness, precision, flute profile, and simulation feeding paper. Special projector is used to check the flute profile and feeding different GSM paper to ensure the performance of corrugating rolls.
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.
