E Flute Hard Chrome Plated Alloy Steel Corrugating Rolls Inner Suction

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.

Intermediate frequency quenching machine.


Polishing machine

3. Flute profile

The most important parameter is the flute profile. To design the flute profile, we must know the corrugated paper gsm, speed, flute height, correct diameter and other requirement such as good FCT, saving paper, etc. Our engineer has rich experience of designing flute profile. Without good design, many problems will appear, such as flute paper broken, low speed, collapsed flute, high-low flute and so on.

The following table is just for a reference.

4. Heat well

A. Start the corrugating rolls before filling in steam to avoid abnormal deformation.

B. Check the temperature of corrugating roll and pressure roll regularly to avoid temperature decrease caused by accumulation of condensate water.

C. If the temperature is abnormal, please check and keep the correct position of siphon to let condensate water out successfully.
