New technology of tungsten carbide corrugating roller

New tungsten carbide corrugating roller

Different from the traditional corrugating roller, the new tungsten carbide corrugating roller process is different from the traditional corrugating roller in that the hardness of the heat treatment in the front substrate is different, and the precision of the tooth profile before the spraying is higher. It must be completed on a fully automatic CNC grinding machine. The second spraying technology is the key to ensure the hardness of the tungsten carbide The force and the quality of the post-polishing process, the most difficult to process is the post-spray polishing technology, because the corrugating roller is different from the general workpiece, its unique tooth profile and surface hardness (such as diamond) of tungsten carbide, the traditional common Grinding wheel can not be carried out at all.

Old Corrugated Roll Remanufacture Tungsten Carbide Corrugating Roller

First, the old roller must be strictly inspected, and then it can be modified into a tungsten carbide corrugating roller (Note: Some old rollers cannot be restructured, as the original heat treatment method is too different).

Repair of tungsten carbide corrugating roller

The new tungsten carbide corrugating roller coating thickness 0.1mm, when the long-term use coating reduction can not be produced, we remove the residual tungsten carbide for you to repair, the corrugating roller diameter hardly changes.

Tungsten carbide corrugating roller advantages

Compared with general corrugating roller, tungsten carbide material has obvious technical advantages, mainly in the following points:

1. Tungsten carbide corrugating roller is 3 to 6 times longer than ordinary corrugating roller.

2. Generally, the tooth height of the corrugation roll changes greatly, and the quality of the paperboard is unstable. When the new roll is used, the gap between the core paper and the rubber roll should be 0.1mm to 0.2mm. However, when the corrugating roll wears 0.1mm in the middle, the gap will expand, resulting in excessive A lot of glue, too much water makes the cardboard soft and easy to bend; Tungsten carbide corrugated roller tooth change is small and long, paper pull quality is straight and stable.

3. Generally, the middle of the corrugating roller wears excessively and becomes concave, so it is impossible to re-produce a wide-format cardboard, resulting in waste paper, because both ends will be crushed or the middle will not be scumming (defoaming and foaming). At this time, you have to grind. Both ends of the roller are used to widen the width of the paperboard to maintain the life of the corrugating roller; the tungsten carbide corrugating roller is not wearable because there is no problem of narrowing the width of the paper and then widening the width of the paper.

4. The general corrugating roll wears fast, so the original design has a higher tooth height (high twist rate) to ensure longevity; the tungsten carbide corrugating roll is designed to have a lower tooth height (small twist rate) and a long life since it is wear-resistant. .

5. Generally, corrugating rollers cannot use V-type boring, because if the cul-de-sac is small, it will be quickly worn out, and the cardboard will become softer and softer; the problem of tungsten carbide corrugating roller does not exist because of wear resistance.

6. Generally, the top of the corrugating roll wears fast and many, and the diameter after repair is much smaller. Because the tungsten carbide corrugating roll wears and has little wear, the diameter after the repair is almost unchanged.

And the most important thing is: The tungsten carbide corrugating roller has almost no change in its roll height throughout the roll's operating life.

With so many advantages, Dasong Tungsten Carbide Rollers can stand proudly in the corrugated packaging industry and become one of the leading companies in the domestic corrugating roller industry with huge sales volume. In addition, Dasong is still developing at an alarming rate and continues to provide customers with better products and services while creating more benefits for customers.
