Tungsten Carbide Corrugating Roll


 

Tungsten carbide corrugated roller has excellent wear resistance and low flute height. Moreover, it will not reduce the compressive strength of the finished corrugated board. A more optimized v-shape flute profile can be designed to increase the strength of the cardboard, reduce the amount of the glue applied and save corrugated paper.

 

Tungsten carbide corrugated roller will never wear in theory, and can ensure the production of high quality finished corrugated board’s durability .

 

The service life of tungsten carbide corrugated roller can reach at least 35 million meters, reducing the number of maintenance and replacement times, saving manpower, material and financial resources.

 

Tungsten carbide roller’s wear resistance is good, and it’s tungsten carbide coating adopts special removing process, so corrugated roller substrate can not be damaged, and corrugated roller can be used for many times with repairing.

Hard Chrome Corrugating Roll


 

At present, most corrugated cardboard manufacturers choose wear-resistant tungsten carbide corrugating rolls. But some micro flutes such as G and N flute, some paperboard required very good FCT, we have to choose hard chrome coating, because tungsten carbide is too hard and special micro flute profile only allow to plate hard chrome. So hard chrome corrugating rolls can’t be replaced by tungsten carbide corrugating roll completely. 

 

Hard chrome corrugating roll is produced by 50CrMo alloy steel. Adopt intermediate frequency quenching heating treatment, ensure the hardness is more than HRC 58. Chrome coating thickness 0.06-0.08mm, enhance the abrasion resistance and prolong the service life.
