External Suction Alloy Steel Corrugating Rolls For F Flute Single Facer

1. Strict Selection of Alloy Steel Corrugating Rolls Material

50CrMo alloy steel in China is supplied by best manufacturer in China. Adequate raw material in warehouse can guarantee the delivery time for our orders.

2.Precision Welding Make Inseparable

The roll barrel and shafts shrink fit together. After welding do tempering to reduce stress. We do steam leak detction.

3. Advanced Equipments

• With advanced intermediate frequency quenching machine to do heating treatment. After harden, the hardness reach to be more than HRC 58 and harden layer 8-12mm.

• High precision grinding machine with Siemens control system is special designed for corrugating rolls. It's important for a high precision corrugating rolls. The flute profile is formed after finish grinding.

• Special polishing mahine and technology for corrugating rolls. Smooth surface can extend the life span of hard chrome corrugating rolls.

Intermediate frequency quenching 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.

Test flute profile with computer and projector.

5. Precision index of alloy steel corrugating rolls
