Product Description

Tungsten Carbide Alloy Steel Corrugating Rolls For Single Facer Corrugated Machine
 
Features of Tungsten Carbide Alloy Steel Corrugating Rolls
 
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.

Production Process
    
⇒ 1. Strict Selection High Quality Material
Good raw material is an important factor in high quality of alloy steel 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.

⇒ 2.High Hardness from Vertical Quenching Process
Intermediate frequency quenching can guarantee both the hardness and harden depth we need. Our harden layer depth can reach to 8-12mm. With harder base material as foundation, the lifetime of our corrugating rolls are greatly extended.

⇒ 3. Rigorous for Precise Grinding
After heat treatment and the cutting slots, the roller shall be put on high precision automatic CNC grinding machine to do finish grinding.  By grinding wheel grind each flute several times until the accuracy is within our technical permitted requirement. The Siemens control system play a key role in guarantee the accuracy.

⇒ 4.Durable from Supersonic Tungsten Carbide Spraying
 Because of the particularity of tungsten carbide material, the requirement of the base material hardness is higher, flute profile before tungsten carbide spraying is more precise, which is needed to match the performance of tungsten carbide. Spraying technology is the key, which can ensure the hardness and binding force of tungsten carbide.Most advanced Praxair JP 8000 HVOF tungsten carbide spraying equipment and technology is adopted and Praxair 1342 super hard tungsten carbide powder is used for our corrugating roll.

⇒ 5.Repeatedly Polished, Smooth As a Mirror
Meijia adopts special polishing crafts, such as the corrugated rollers use America Praxair 1342VM series super hard tungsten carbide roller, special customized polishing wheel. With our company’s fully automatic CNC corrugated roller producing process’s special polishing machine and our independent grinding polishing technology R&D, the tungsten carbide roller’ s surface finish degree can reach Ra<0.6μm, which will improve the accuracy of the flute profile, and make sure the quality of the corrugated roller.

⇒ 6.Strict Test to Keep Improving
Before and after the surface treatment including tungsten carbide plating or hard chrome coating of corrugating rolls, it is needed to check the size, hardness, precision, flute profile, and simulation feeding paper. Special projector is used to check the flute profile and feeding different GSM paper to ensure the performance of corrugating rolls.
