Tungsten Carbide Corrugated Paper Rolls And Rolls
product description:
The super wear-resistant tungsten carbide corrugated paper roll
grinding shaft material is made of 50CrMoA alloy steel forgings.
The hardness and the wear resistanceis second only to diamond. It is suitable for high-speed operation
of corrugated paper to reduce vibration and noise.

Advantange corrugated roll:
1. The coating is firmly combined with the substrate to ensure
long-term use of the coating without falling off;
2. The hardness of the coating is high, the wear resistance is
doubled, and the life is linearly extended;
3. The coating thickness is uniform and controllable, which can
ensure the accuracy of the corrugated wheel;
4. The surface roughness before coating can reach ra0.3-0.5um.
After grinding with a special diamond grinding wheel cutter, the
surface roughness reaches and is higher than that of the
electroplated hard chrome roller.
5. With UV-type and UVV-type corrugated design, it can effectively
improve the hardness of the cardboard and reduce the amount of
paste and the waste of core paper;
6. When the corrugated type is used, there will be abrasion in
theory, and the paper output rate will remain unchanged for a long
time;
7. Since the corrugating roller used this machine, the thickness of
the cardboard produced remains unchanged, the printing is always
smooth, and the quality of the cardboard and cartons is stably
controlled;
8. Using special methods to remove the coating, the wheel blank can
be reused;
9. The extension of the service life reduces the frequency of
replacement, and also saves labor and material costs;
