Product Description

Product Description

The vacuum return roll is used in the forming part of the paper machine. It has the same structure as the vacuum press roll and is usually equipped with an auxiliary drive. When the lower felt with paper and the upper felt meets the lower felt at the return roll, an upper roll is added to the vacuum return roll to form a return roll press. Before the upper felt enters the return roll nip area, it is also necessary to use a suction box to make it as dry as possible, and a pre-wrap section is set on the return roll to remove air and gradually increase the degree of pressure on the paper web.

The adhesive layer have good elasticity, compression resistance, flex resistance and thermal conductivity.

The maximum tolerance of the hardness should be within the allowable range, otherwise the unevenness of the pulp will be uneven and the quality of the paper will be affected.

Generally, the Shore hardness is 40°~100°, and the tolerance is ±2°~±4°.
Stainless steel rolls body have the following advantages over tin bronze rolls:

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 corrosion cracking 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.
