Back up Rolls for Tension Levelers: The Foundation of Precision

Overview: The Core of Rigidity, Stability, and Accuracy

In the precision world of the tension leveler, if the work rolls are the “spearhead” executing the leveling task, then the backup rolls are the “foundation” that provides steadfast support and safeguards the accuracy of the entire system. Although they never contact the strip directly, their design and condition fundamentally determine whether the work rolls can function stably and precisely. Their core mission is to provide an absolutely solid support for the array of small, densely-packed work rolls, absorb the massive leveling reaction forces, and prevent the work rolls from deflecting under load, thereby ensuring consistent leveling force across the entire length and width of the strip.

A well-designed and properly maintained back up roll system is the prerequisite for achieving exceptional and stable shape quality, as well as high equipment reliability and longevity.
