Newly made tungsten carbide corrugated roll
The process of the new tungsten carbide corrugated roll is different from the traditional corrugated roll. First, the hardness of the front substrate is different from the heat treatment. The accuracy of the tooth shape before spraying is higher. It must be completed on the fully automatic CNC grinding. Force and the quality of the subsequent polishing process, the most difficult to process is the polishing technology after spraying. Because the corrugated roller is different from the general workpiece, the uniqueness of the tooth profile and the extremely high surface hardness (such as diamond) of tungsten carbide, the traditional ordinary Grinding of wheels is simply impossible.
Conversion of old corrugated roller to tungsten carbide corrugated roller
First, the old roller must be strictly inspected, and then it can be converted into a tungsten carbide corrugated roller (note: some old rollers cannot be modified, such as the original heat treatment method is too different).
Repair of Tungsten Carbide Corrugated Roller
The thickness of the new tungsten carbide corrugated roller coating is 0.1mm. When the coating is reduced for a long time and cannot be produced, we will remove the residual tungsten carbide and repair it for you.
Advantages of tungsten carbide corrugated roller
Compared with general corrugated rollers, tungsten carbide materials have obvious technical advantages, mainly concentrated in the following points:
1. The life of tungsten carbide corrugated roller is 3-6 times longer than that of general corrugated roller.
2. Generally, the tooth height of the corrugated roller varies greatly, and the quality of the cardboard is unstable. The gap between the core paper and the glue roller should be 0.1mm to 0.2mm when the roller is new. The large amount of glue and excessive moisture make the cardboard soft and easy to warp; the tungsten carbide corrugated roller tooth height change is small and long, and the quality of the paper wrench is straight and stable.
3. Generally, the corrugated roller wears too much in the middle and becomes concave, so it is impossible to produce wide-width cardboard and produce waste paper, because the two ends will be crushed or there is no glue in the middle (degumming and foaming), then you have to grind The two ends of the roller are used to widen the cardboard to maintain the life of the corrugated roller. The tungsten carbide corrugated roller is wear-resistant, so there is no problem of narrowing the paper and then widening the paper.
4. Generally, because the corrugated roller wears fast, the original designed tooth height is higher (the corrugation rate is large) to ensure the life; the tungsten carbide corrugated roller is designed with a lower tooth height (small flute rate) and long life because of the wear resistance. .
5. Generally, corrugated rolls cannot use V-shaped corrugated rolls, because if the corrugated top is small, it will be quickly worn away, and the cardboard will become softer and softer; tungsten carbide corrugated rolls do not have this problem because of wear resistance.
6. Generally, the crest of the corrugated roller wears quickly and much, and the diameter is much smaller after repair; the tungsten carbide corrugated roller is almost unchanged after repair because of wear resistance and less wear.
The most important thing is: the corrugated height of the tungsten carbide corrugated roller is almost unchanged during the entire operating life of the roller.
With so many advantages, Dasong tungsten carbide corrugated rolls can stand proudly in the corrugated packaging industry and become one of the leading companies in the domestic corrugated roll industry with huge sales. Moreover, Dasong is still moving forward at an alarming speed, constantly providing customers with better products and services, while creating more benefits for customers.
