Breast Roll For Paper Roll
Description:
Breast roll is also an accessory of paper machine, and paper machine breast roll is mainly for supporting forming section to achieve the purpose of dehydration. Breast roll is the reversing roller of paper machine Forming Wire. The Paper Making Rolls -Breast roll need to have good stiffness, and have a larger radius of curvature for copper wire mesh in paper production line.
Specification:
1.Rubber coating thickness: 10-12mm
2.Shell material: Seamless carbon steel pipe or rolling plate
3.Shaft head: 45#round steel, Bulkhead: QT235
4. Bearing housing: Cast iron or SS material
5.Diameter of roll: 100-2000mm
6.Face length: 12000mm(Max)
7.Working speed: Up to 2000m/min
Advantages:
1. Has higher rigidity and mechanical strength. Its tensile yield strength and impact toughness are more than double that of copper, which is conducive to improving the dehydration rate.
2. Has higher hardness and abrasion resistance, good impact toughness. It does not deform during long-term high alternating load operation, which is incomparable with copper structure.
3.It has high hardness and abrasion resistance, has extremely high corrosion fatigue strength and ability to resist crack corrosion and corrosion wear, which is 2-3 times that of copper alloys, and the service life is also increased by more than 2-3 times.
