F Flute Traditional Corrugating Roll Tungsten Carbide Spraying
1. Introduction
| The largest professional corrugated roller manufacturer in northern of China |
| 50CrMo refined forging steel supplied by the best manufacturer in China. |
| A, C, B, E, F, G, N flute corrugated rolls |
| High Speed can reach to 250-300m/min |
| American Praxair JP8000 HVOF tungsten carbide plating equipment |
| American Praxair super-hard 1342 tungsten carbide powder |
| Medium frequency quenching heating treatment machine makes the hardness of base steel more than HRC58 and harden layer 8-12mm. |
| High precision and high performance CNC grinding machine equipped with Germany Siemens control system. |
| We design the flute profile according to customer’s medium paper GSM, speed, FCT requirement. The flute profile is more reasonable, suitable to customer’s machine |
| Tungsten carbide corrugated roll lifetime is 3-5 times longer than hard chrome roll because of its excellent wear-resisting property |
| Our corrugated rollers has been exported to many countries such as Korea, Russia, Egypt, India, Thailand, Myanmar, etc. |
| Supply corrugated rollers for all kinds of corrugator line such as Fosber, BHS, BW Paper System, K&H, HSIEH HSU,Fuli, Wanlian, TCY, Champion, West River, Mingwei and so on. |
2.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.
