High Speed Traditional Corrugating Roll Tungsten Carbide Corrugated Roll
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.
2. Store well
⇒ Store in dry places.The surface of corrugating rolls is not compact structure. The permeation and corrosion of water and steam will cause unusual falling off of coating.
⇒ Apply silicon oil. The silicon oil is valid for 3 months. If you don’t use corrugating rolls for a long time, silicon oil must be applied to the rolls regularly to avoid unusual falling off of coatings caused by the permeation and corrosion of water and steam.
⇒ Keep the surface clean. If you put the corrugating rolls in the warehouse, the surface should be cleaned and applied silicon for later use.
3. Clean well
⇒ Don’t wash the corrugating rolls directly when the rolls are hot.
⇒ After the corrugating rolls cool down, wash the rolls by water or gas.
⇒ Clean the glue and paper scraps on corrugating rolls after production to avoid scratches of coatings.
⇒ After cleaning, apply silicon oil on corrugating rolls.
4. Flute Profile
Almost every set of corrugating rolls are needed to be designed and customized separately according to the width, diameter, flute height, corrugated paper GSM, speed and cardboard physical index requirement.
