C Flute Alloy Steel Corrugating Rolls , Steam Heating Tungsten Carbide Corrugator Rolls
Advanced Equipments for Alloy Steel Corrugating Rolls
* Harden the tungsten carbide corrugating roll surface, make the hardness more than HRC58, harden depth 8-12mm.
* Special grinding machine for corrugating rolls with Siemens control system.
* Sand blasting make a rough surface of the roll. It's to increase adhesion of TC powder.
* American Praxair JP8000 HVOF tungsten carbide plating machine is the most advanced in the world.
* Smooth surface can extend the life span of tungsten carbide corrugating rolls.
Intermediate frequency quenching machine.

Flute profile
The designed parameter of flute is not in line with the manufacturing parameters, and the smooth finish of the roll surface is inadequate,causing a high tension of corrugating roll during the running process,that made a poor meshing and resulting in fluting paper broken.The most important parameter is the flute profile. To design the flute profile, we must know the corrugated paper gsm, speed, flute height, correct diameter and other requirement such as good FCT, saving paper, etc. Our engineer has rich experience of designing flute profile.
The following table is just for a reference.
