Tungsten carbide corrugating roller

As a corrugated roller in the heart of a single machine, it plays a decisive role in the quality of corrugated board, and also has a direct impact on economic efficiency. Before 2005, high-quality corrugated rollers were dominated by corrugated roller manufacturers from abroad, and the Chinese were only able to appreciate the high-quality tungsten carbide corrugating rollers. In February 2005, Shanghai Dasong Waqiu Roll Industrial Co., Ltd. officially launched the carbide corrugating roller to the market, becoming the first domestic carbide producer.

The carbide corrugating roller adopts high density, high hardness and strong abrasion resistant carbide alloy powder as a coating, and the thermal spraying is used to spray the fluid coating onto the finished and finely-treated barrel.

Compared to ordinary corrugating rollers, carbide corrugating rollers have the following advantages:

The carbide coating with excellent wear resistance allows the corrugating roller to be designed in an ideal condition, so that the optimum tooth design can be obtained to obtain the ideal shape.
The increase of the top circle after the wear of the ordinary corrugated roller will lead to a large amount of glue and affect the quality of the cardboard. The carbide corrugating roller can ensure that the tooth height and the top circle remain the same for a long time and the quality of the cardboard is stable.
Reduce the amount of core paper by 2 to 8%, reduce glue usage, reduce waste, reduce the number of corrugating roll replacements, and reduce damage to other groups.
Easy to repair, the diameter of the corrugated roll after the repair is almost unchanged, and the corrugated roll after re-spraying can also reach the life of the new carbide corrugating roll.
