Tungsten Carbide Coating Corrugated Rollers For BHS Corrugated Machine
1. Features of Tungsten Carbide Alloy Steel Corrugating Roll
a. Tungsten carbide corrugated roller has excellent wear resistance and low flute height. Moreover, it will not reduce the compressive strength of the finished corrugated board. A more optimized v-shape flute profile can be designed to increase the strength of the cardboard, reduce the amount of the glue applied and save corrugated paper.
b. Tungsten carbide corrugated roller will never wear in theory, and can ensure the production of high quality finished corrugated board’s durability
c. 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.
d. 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.
2. Advantages
☆ The domestic first-class technology and core operating team, each member has rich experience with processing more than 5000 sets of corrugated roller. Depending on the mature stable Taiwan craft technology and the advanced international technology, we offer the optimized design of corrugating roll flute profile totally according to costumer’s requirement.
☆ The CNC intermediate frequency heat treatment quenching machine adopts the foreign corrugating roll quenching technology and makes the hardness of the substrate reach more than HRC58 degrees, meanwhile it retains the toughness and maximizes the anti-thermal deformation of substrate to ensure the stability of corrugating rolls.
☆ The leading domestic high precision and high performance CNC corrugating roll precision grinders, lathe, planer, and other equipment are equipped with Germany's Siemens control system, increase grinding accuracy in the maximum.
☆ With the mature of tungsten carbide plating technology, the most advanced tungsten carbide coating equipment Praxair JP8000 , as well as high quality imported Praxair tungsten carbide powder, the abrasion performance of corrugating roll is extreme and maximize the extension of the service life of the corrugating roll.
☆ Good raw material is an important factor in high quality of corrugating roll. We select the best raw material manufacturer in China. With high strength and toughness, good hardenability, no obvious temper brittleness, 50CrMo alloy steel is specialized material for manufacturing corrugating rolls. Our raw material shell thickness is more than 70mm, the thicker shell can reduce deformation and keep stability during production.
