Sand Blasting HVOF Tungsten Carbide Corrugated Roller

Tungsten Carbide Corrugating Rolls For Taiwan Yueli Single Facer

1. Advanced Equipments

♦ 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.

2. Flute profile

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. Without good design, many problems will appear, such as flute paper broken, low speed, collapsed flute, high-low flute and so on.

The following table is just for a reference.
