Tungsten Carbide Corrugating Rolls

Key Features of Tungsten Carbide Corrugating Rolls
Using the world's advanced supersonic spray equipment American Praxair JP800, the spray flame and powder particles have low temperatures (<1400℃) and high particle speeds (>800m/s). Tungsten carbide coating has high hardness (HV0.3>1200) and good wear resistance, which is 5-8 times that of electroplated hard chromium rollers. Tungsten carbide coating is dense and has good corrosion resistance.
The coating is firmly bonded to the base (bonding strength 6b>70N/mm²) and will not fall off for a long time (the longest service life is 160 million meters)
During the spraying process, the corrugating roller temperature is lower than 80℃, the corrugating roller run-out increment is ≤0.01mm, the tungsten carbide coating is uniform, and the thickness tolerance is ≤0.01mm.

Advantages of Tungsten Carbide Corrugating Rolls
1. The coating is firmly bonded to the base material, ensuring that the coating will not fall off after long-term use;
2. The coating has high hardness, the wear resistance is multiply increased, and the service life is linearly extended;
3. The coating thickness is uniform and controllable, and the accuracy of the corrugating roller can be guaranteed;
4. After coating treatment and a special polishing process, the surface roughness can reach Ra0.4~0.6, which can fully meet the production needs of high-speed machines;
5. With the UV and UW flute design, it can effectively improve the hardness of the cardboard and reduce the amount of glue and the waste of corrugated paper;
6. The corrugated type will theoretically never wear out during use and can ensure that the paper usage rate remains unchanged for a long time;
7. After the corrugating roller is used on the machine, the cardboard produced is maintained at a certain thickness, the printing is always smooth, and the quality of the cardboard and cartons is stably controlled;
8. The coating is removed using special methods, and the roller can be refurbished;
9 .The increase in service life reduces the number of replacements, which also saves labor and material expenditures.

Comparison Between The Ordinary

Roller and The Tungsten Carbide Corrugated Roller

 

Item

Ordinary Corrugated Roller

Tungsten Carbide Corrugated Roller

Flute Profile and T.U.R

Due to the poor wear resistance of ordinary corrugated rollers, the original flute design has a higher flute height to ensure service life, resulting in a higher T.U.R;in order to achieve a certain service life, the design of the corrugated tip of ordinary corrugated rollers is relatively round, and the T.U.Ris also higher.

The hardness and wear resistance are high, and the lower flute height design, which saves paper. No worry of the wear of the corrugated tip will reduce the compres-sive strength of the finished product and affect quality problems. It can design a sharper tooth type, thereby increasing the strength of the cardboard. reducing the amountof glue usage and the medium paper is saved.

Cardboard Thickness

Due to the worn-out during use, the height decreases, and the thickness of the cardboard decreases accordingly, constantly changing.

The tungsten carbide roller theoretically never wears out, and the thickness of the cardboard is always uniform, ensuring the continuity of quality.

LifeTime

Service lifetime is generally 6-8million linear meters

The tungsten carbide corrugated roller can reach at least 30million meters ormore, reducing the frequency of replacement and saving manpower and material expenses.

Base Material Usability

Due to severe worn-out need to reduce the outer diameter and hardness everytime when repairing, resulting in an increase in paper usage and fewer refurbished times.

Tungsten carbide corrugated rollers do not have this problem, and their coatings are removed with special methods, making the rollers reusable.

Zhejiang Yonghui Corrugated Roller Co.,Ltd
Since its establishment in 2004, Zhejiang Yonghui Corrugated Roller Co., Ltd. has always focused on the R&D and manufacturing of high-quality corrugated rollers, the "heart" component of the corrugated cardboard production line.
With a scientific attitude and professional research and development team, we continuously break through the boundaries of corrugated declare to meet the needs of high-speed, wide-width, and lightweight paper in corrugated cardboard production lines.
With 20 years of profound industry experience, we continue to provide customers with high-quality products, Combined with a huge strategy database, each pair of corrupting rollers is no longer a cold metal, but an "engine" that continuously creates value for customers.
With the spirit of craftsmanship, we meticulously grind over 40 production processes. ensure the high precision of the roller body, with a surface the roughness of Ra 0.4-0.6, to meet the continuous operation of the corrugated line at a speed exceeding 300 meters. Ado being American Praxair super hard alloy tungsten carbide powder, combined with advanced supersonic spraying equipment in the world, the hardness and high wear resistance of the corrugated roller surface are second only to diamond, providing customers an ultra service life of over 40 million meters.
The meticulous calibration and quality controls of each process are a solemn commitment to customers and do not disappoint their expectations More than 20 sales and after-sales teams promote services covering the whole country Together with customers, we explore the latest design process es for corrugated rollers that meet their needs, and provide process on technical support to continuously create greater value for customers.
Nowadays, over 3000 pairs of corrugated rollers are running on over 1000 corrugated cardboard production lines in real-time faced with high-speed production lines and increasingly lightweight cardboard, we will always be committed to improving the manufacturing process of corrugated rollers, exploring the unknown with technology, and driving the future with data.
