C Flute Fuli SF22NA Single Facer Corrugating Rolls

Tungsten Carbide Alloy Steel Corrugating Rolls For Fuli SF22NA Fingerless Single Facer

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.

5. Precision

Zhejiang Yonghui Corrugated Roller Co., Ltd. is a professional manufacturer of high-quality corrugated rollers with professional production equipment and strong technical strength.

Since its establishment in 2004, we have been devoted to the design and research and development of high-quality corrugated rollers; We have professional production technology, experienced professional design, independent research and development capabilities, and a qualified after-sales service team; complete production process, fully automatic CNC precision grinders, and use the American JP8000 supersonic tungsten carbide spraying equipment, which is currently the most advanced supersonic spraying equipment in China. Ensure that every design and production can meet the needs of customers and achieve customer value.

All products have been ground with the highest precision CNC grinding machine, with a roundness tolerance of 10 μ M. Adopting nitrogen hardening and medium frequency induction quenching processes, ensuring high hardness and wear resistance of corrugated rollers, and extending their service life. Our company can produce corrugated rollers for all models of single faces.
