1. Strict Selection of Corrugated Roller Material

The uneven of raw material of corrugating roll leads to the uneven of inner heat transfer, of expansion while working, and distortion.This will cause poor formation of fluting paper which resulting in collapsed flute. With high strength and toughness, good hardenability, no obvious temper brittleness, special Steel D50CrMo is used as the material to producing corrugating roll.It is the premium alloy precision forging steel featuring stable property and even heat transfer. Our raw material shell thickness is more than 70mm, the thicker shell can reduce deformation and keep stability during production.

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 s...
