Application
Corrugating roll is one of the most important components in corrugated carton production. Usually, it is an essential part of single facer. Corrugating rolls consist of two parts: upper roll and lower roll. The lower corrugating roll is the driving roll, which is generally fixed while the upper one is the driven roll.
To meet the requirements of corrugated board production, a special tungsten carbide coating was developed. This unique coating process achieves excellent quality with a high degree of hardness, excellent resistance to wear, excellent bonding of the layer to the basic material and a low degree of roughness.
Do your corrugated paperboard production have those problem as followed?
1. 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.
2.The designed parameter of flute is not in line with the manufacturing parameters, and the smooth finish of the roll surface is inadequate,causing a high tension of corrugating roll during the running process,that made a poor meshing and resulting in fluting paper broken.
3.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.
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.
