A Flute Traditional Corrugating Roll Electrical Heating Tungsten Carbide
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.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 rol
3.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.
Flute Profile
Almost every set of corrugating rolls are needed to be designed and customized separately according to the width, diameter, flute height, corrugated paper GSM, speed and cardboard physical index requirement.
