The Roll cassette of the multi-roll Tension Leveler, as an integrated core functional unit of the multi-roll tension Leveler, integrates multiple sets of Work Roll, backup roll, and roll gap adjustment devices.

It precisely eliminates internal residual stress in metal plates and strips by applying alternating elastic-plastic bending deformation, effectively improving various plate shape defects. It directly determines the final straightening accuracy of the tension levelling process and is an indispensable core key component in the field of high-end plate and strip precision processing.
