Hard Chrome Corrugated Roll
We choose high-quality alloy steel forgings, and the steel has a balanced metal composition to reduce impurities. After heat treatment, corrugated design, roll surface processing technology, surface treatment, surface tungsten carbide coating or surface hard chrome coating, polishing treatment, a series of processes are produced.
The corrugating roller is used to corrugate the base paper on a single-sided machine. A single facer needs to use two upper and lower corrugating rolls and a pressure roll.
The corrugated roller is made of alloy steel, solid forged, deep hole machine pond hole processing, divided into three parts, roller body and 2 shaft heads
Used on single-face machine, it is divided into upper corrugated roller and lower corrugated roller. The upper and lower roller surfaces are tooth-shaped, and the two rollers are matched and assembled.
The function is to form a layer of corrugated core paper on a single sided machine by paired corrugating rollers.
Combined operation with glue roller and pressure roller to make one layer of corrugated paper and one layer of paper bonding.
1. Surface tungsten carbide coating: In the design of the flute height, due to the wear resistance of the tungsten carbide corrugating roller, the initial flute height can be reduced, the shrinkage rate of the core paper can be greatly reduced, the base paper can be saved, and the efficiency can be improved. The service life is greatly improved, the number of replacements is reduced, and the expenditure of labor and wearing parts is saved. Tungsten carbide coating thickness 60um, hardness HV1250
2. Surface chrome coating Thickness of chrome coating 100 120um, hardness HV900 950
