50CrMo HRC58 Tungsten Carbide Corrugating Rolls

50CrMo Tungsten Carbide Corrugating Rolls BHS Corrugation Machine Parts

1. Strict Selection of Tungsten Carbide Corrugating Rolls Material

Raw material 50CrMo alloy steel is the best in China . Barrel thickness >70mm. Adequate raw material in stock can guarantee the delivery time for our tungsten carbide corrugating rolls.

2.Precision Welding Make Inseparable

The roll barrel and shafts shrink fit together. After welding do tempering to reduce stress. We do steam leak detction too.

3. 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.

4. Flute profile

Flute profile is the most important parameter. To design the flute profile  pls provide us 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.
