| Tungsten carbide corrugated roll lifetime is 3-5 times longer than hard chrome roll because of its excellent wear-resisting property |
| Our corrugated rollers has been exported to many countries such as Korea, Russia, Egypt, India, Thailand, Myanmar, etc. |
| Supply corrugated rollers for all kinds of corrugator line such as Fosber, BHS, BW Paper System, K&H, HSIEH HSU,Fuli, Wanlian, TCY, Champion, West River, Mingwei and so on. |
Do your corrugated paperboard production have those problem as followed?
1. The insufficient precision of corrugating roll and unstable materials lead to the flute teeth deforming during the running process, which can cause bad meshing and unstable operation,and resonance will be occurred while critical value being reached.This is how high-low flute being caused in corrugated board.
2.The uneven of raw material of corrugating roll leads to the uneven of inner heat transfer, of expansion while working, and distortion.This will cause poor formation of fluting paper which resulting in collapsed flute.
3.If the camber of corrugating roll is designed irrational, it will cause uneven local pressure, which leads to a series of problems such as poor lamination, inner liner frothing, heavy scoring on inner liner, corrugating paper rippling etc.
After making concerted efforts in R&D and manufacturing through many years, Qingdao Meijia has perfectly solved the technical problem that the production loss being caused due to the insufficient quality of corrugating roll.
A. Meijia,in accordance with the different customer needs and on-site situation, has developed special flute type,which circle parabola is adopted for the medium-high outline,solving the problems like collapsed flute,poor lamination,inner liner frothing,heavy scoring on inner liner from the very beginning.
B. Special steel D50CrMo is used as the material to producing corrugating roll.It is the premium alloy precision forging steel featuring stable property and even heat transfer.
C. With scrupulous attitude, Meijia adopted multi-directional detection to enable the parameter of the produced corrugating roll perfectly match that of the designed one. In this way, to keep a smooth and stable operation. The unique tungsten carbide techniques largely improves the abrasive resistance and extend the service of life of corrugating roll. The special polishing method enables the surface finish reach Ra＜0.3μm, successfully solving the problem of broken fluting paper owing by its technical defects.
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.
