Introduction of Tungsten Carbide Corrugating Rolls

Corrugating roll, as the most important part of corrugated cardboard production line, whose abration resistance and service life is the main technical index for measuring quality and economical eficiency, directly influences the economic benefits of manifacturer corrugated cardboard. Controlling on producing cost matters manufacturers competitivefess and survial development ability as low profit generation approaching.

Benefits of tungsten carbide corrugating rolls :

1. Strong combination between coating and matrix ensuring long service life of coating without any peeling.
2. With higher hardness of coating, abrasion resistance will increase manyfold and service life will be prolonged linearly.
3. Thickness of coating could be even and accurately controlled, ensuring precision of rolls.
4. Surface roughness of coating will reach to Ra 0.4-0.6 after special fine polishing, pretty suitable for high-speed corrugated cardboard making machine.
5. Maching with flute designs of UV and UVV type, increase efficiently hardness of cardboard and deduct wasgate of paste and medium paper.
6. Theoretically, flutes in service will be never worn and take up ratio will be never changed.
7. By using tungsten carbide corrugating rolls, cardboard will be maintined at certain thickness and printed always flat for stable quality of cardboard and carton.
8. Used coating could be removed by special process and the rolls could be regurbished for reuse.
9. Improvement in service life deducts frequencies of changing, saving expenditure of manpower and material resources.
