Tension leveler line

Aluminum strip bending plastic deformation occurs under the pressure of straightening roll when straightening on roll stretch straightening machine; Aluminum strip straightening on tension straightening machine produces uniform tensile stress on cross section under the action of tension roll, that is to say, uniform plastic elongation deformation is obtained. However, when the strip is straightened on the continuous stretching and bending straightener, it is not only stretched by the tension roll, but also repeatedly bended by the bending roll. Therefore, the strip is straightened under the combined action of stretching and bending deformation.
