2. Precision Welding Can Be 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. When everything is ready, a driving fit interface has been formed between the roller body and the spindle heads by means of preheating, welding or bolting. Special care should be taken when welding, because finished corrugated roller body’s temperature will rise constantly when the roller is running, and the roller body also bears pressure of the steam from the inside of the roller body, which will form the so-called “pressure vessel”. In view of this, the roller body and the spindle heads joint must pass the pressure test. When the welding process finished, the work piece shall be put into the furnace for high temperature tempering to reduce stress.

3.High Hardness from Vertical Quenching Process

 

Intermediate frequency quenching can guarantee both the hardness and harden depth we need. Our harden layer depth can reach to 8-12mm. With harder base material as foundation, the lifetime of our corrugating rolls are greatly extended. After different heat treatment process, the corrugated roller surface becomes more wear-resistant and durable. Some manufacturers groove their lower rollers before the rollers’ were harden, because it is relatively easy to work with soft materials. By this could cause problems in the later heating process for the rollers, which will make the hardness of the rollers change. After heating treatment we cut slots of lower roll though this process needs more time but makes uniform hardness.

Flute Profile

 

Almost every set of corrugating rolls are needed to be designed and customized separately according to the width, diameter, flute height, corrugated paper GSM, speed and cardboard physical index requirement.
