Tungsten carbide fluted roll
The excellent economy performance of super wearable carbonized tungsten coating corrugating roll
1. The hardness is approach to diamond excellent wearable performance.
1) The life is 3-5 times than chrome plated corrugating roll.
2) Decrease the change time and cost by 65-80% (include the stop and change expenses)
3) Increase the times to repair
4) Reduce the cost of corrugating cardboard
5) Avoid current depreciation of related parts caused by concave abrasion (such as glue roll, doctor roll and pressure roll and so on)
2. The stable quality of corrugating cardboard
Because of the excellent wearable, the flute height abrasion is between 0.006-0.008mm once a time in use. Meanwhile, the flute won’t distort after optimization, and the amount of glue won’t increase with the abrasion of flute top. So it avoids kinds of limitation of common cardboard, and insures uniform quality of corrugating cardboard.
3. Reduce the material consumption cost of corrugating cardboard
1) After optimization, the super wearable carbonized tungsten coating corrugating roll can get the flute of less paper consumption rate.
2) The less abrasion of the flute height can decrease more than 1% paper consumption rate than chrome plated corrugating roll.
3) The less abrasion of flute top can make the glue amount less and more stable, and reduce the glue cost more than 20%.
4) Avoid the quality limitation of kinds of common cardboard, and decrease the wastage loss by 30-50%.
4. The technical index of super wearable carbonized tungsten coating corrugating roll
(1) Special 48CrMo alloy steel fine forgings for corrugating roll
(2) Hardness of base unit > HRC58
(3) Coating thickness is 0.06-0.08mm
(4) Coating hardness >HV1250-1400
(5) Combination hardness >75MPa
(6) Porosity <1%
(7) Optimizing design for economical flute
(8) Precision Index of High-speed Corrugating Roll
1) Flute height limits of deviations ≤0.025mm
2) Addendum circle runout tolerance ≤0.025mm
3) Tip cylinder element linear ≤0.02mm
(9) Fine grinding and polishing gear surface, roughness Ra≤1.6μm
