Corrugating rolls are the core element of each corrugator and are essentially responsible for the quality of the corrugated board and the productivity of the corrugator.
1. Strict Selection of Alloy Steel Corrugating Rolls Material
Raw material use special 50CrMo alloy refined forging steel, the steel body wall thickness is more than 70mm.
2.Precision Welding Make Inseparable
Both ends of the roller body should be heated to release the size of the inner bored hole. After the spindle heads are put in, the roller body and the spindle heads should be held tightly after natural cooling.
3. Advanced Equipments
Advanced CNC machine equipped with Germany’s Siemens control system increase corrugated roller precision in the maximum degree that error limits should be controlled ±0.01mm.
High precison grinding machine with Siemens CNC system.
The tungsten carbide alloy steel corrugating roll's surface finish degree can reach Ra<0.6μm, which will improve the accuracy of the flute profile, and make sure the quality of the corrugated roller.
Polishing machine
4. QC
Flute profile test and paper test would take during grinding, after coating, after polising and finished prodcuts inspection. We make sure every set of corrugating rolls 100% qualified.
