F Flute Hard Chrome Alloy Steel Corrugating Rolls for Good Printing Make-up Packaging

1. Strict Selection High Quality Material

Good raw material is an important factor in high quality of corrugating roll. We select the best raw material manufacturer in China. With high strength and toughness, good hardenability, no obvious temper brittleness, 50CrMo alloy steel is specialized material for manufacturing corrugating rolls. Our raw material shell thickness is more than 70mm, the thicker shell can reduce deformation and keep stability during production.

2. 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.

3.Follow our suggestion to clean the alloy steel corrugating rolls well

⇒ Don’t wash the corrugating rolls directly when the rolls are hot.

⇒ After the corrugating rolls cool down, wash the rolls by water or gas.

⇒ Clean the glue and paper scraps on corrugating rolls after production to avoid scratches of coatings.

⇒ After cleaning, apply silicon oil on corrugating rolls.
