A flute Hard Chrome Plated Corrugated Roller Electrical Heating 1650mm Width
Comparison Between Tungsten Carbide Roller and the Hard Chrome plated Roller
| Compared Item | Hard Chrome Plated Corrugated Roller | Tungsten Carbide Corrugated Roller |
| Flute profile and TUR | Due to the poor wear resistance of chrome-plated corrugated roller, in order to ensure the wear height is not lower than the standards,the tooth profile needs to be designed higher accordingly. | Tungsten carbide corrugated roller has high hardness, excellent wear resistance and low tooth height. Moreover, it will not reduce the compressive strength of the finished products due to the wear on the top of the tooth. A more optimized v-shape tooth can be designed to increase the strength of the cardboard, reduce the amount of the glue applied and save corrugated paper. |
| Thickness of finished board | Using chrome corrugated roller will lead to wear, and the height of the flute will be lower, so the thickness of corrugated board will be decreased. | Tungsten carbide corrugated roller will never wear in theory, and can ensure the finished corrugated board’s durability from high quality production. |
| Service life of corrugated roller | The service life of chrome-plate corrugated roller is generally between 8-12 million meters. | The service life of tungsten carbide corrugated roller can reach at least 35 million meters, reducing the number of maintenance and replacement times, saving manpower, material and financial resources. |
| Usability of corrugated roller’s substrate | Because chrome corrugated roller wear resistance is poor, and repair at every time will reduce the corresponding diameter and hardness. Paper rate will be increased accordingly, and the number of repair will be less. | Tungsten carbide roller’s wear resistance is good, and it’s tungsten carbide coating adopts special removing process, so corrugated roller substrate can not be damaged, and corrugated roller can be used for many times with repairing. |
QC
Before and after the surface treatment including tungsten carbide plating or hard chrome coating of corrugating rolls, it is needed to check the size, hardness, precision, flute profile, and simulation feeding paper. Special projector is used to check the flute profile and feeding different GSM paper to ensure the performance of corrugating rolls.
Test flute profile with computer and projector.
