B Flute Corrugation Machine Parts Tungsten Carbide Corrugated Rolls
1. Features of Tungsten Carbide Corrugating Roll
a. 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.
b. Tungsten carbide corrugated roller will never wear in theory,
and can ensure the production of high quality finished corrugated
board’s durability
c. 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.
d. 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.
