For any form of corrugated roll, it has the same basic function and wear mechanism.Corrugated base paper in high speed, continuous section into the ironing forming process, the online pressure continuously with corrugated roller stare blankly peak relative displacement and produce friction JiGa, the base paper and mineral inclusions in hard grain crushing impact, make corrugated roller stare blankly at the top of the intense wear occurs, and gradually by the circular grinding into irregular shape, continuous high-speed operation, while the tooth height slowly become low, gradually incline to the production of cardboard standard limit.Some corrugated surface hardness of corrugated roll will therefore make corrugated top corrugated surface pitting and depression, aggravating the wear process.

Because the production line is often not always full of paper, resulting in uneven wear corrugated roller surface resulting in corrugated roll concave and resulting in the middle of the board degumming blister.Low hardness corrugated roll in continuous high speed single tooth meshing directional operation condition will also occur due to plastic deformation chamfering, tilt, twist, increase ellipticity and run-out error, accelerate the impact of corrugated roll service life and economic performance.
