Tension leveling, also known as ABT, consists of subjecting the strip of sheet metal to a traction force sufficient to exceed the yield stress of the fibers making up the material, combining this lengthening with simultaneous deformation of the strip caused by inter-meshing of the leveling rolls. It is this combination that distinguishes tension leveling from traditional leveling in the so-called multi-roll levelers, with improved flatness being achieved. The entry and exit bridles and the intermediate roll leveler are at the core of the installation. The traction bridles are normally equipped with 2, 3 or 4 rolls, depending on the traction required for leveling. The traction bridles allow very high strip traction to be obtained. Within the individual configuration, each bridle is driven by an electric motor, and the leveler is located between the two bridles. For soft or thin materials, one set of leveling rolls is sufficient. However, for materials with a high yield stress and for thick metals, the leveling process is more efficient when two sets of rolls are used. The leveling beams may be of 2 or 3 different heights, depending on the material to be processed. For delicate materials such as galvanized steels, tin steels or aluminum and thin metals, it is preferable to use leveling beams with 3 heights. The process may be either wet or dry.
