Good shape is available. After stretching and straightening, it can1 completely eliminate the wave edge, wave shape, ladle and mild sickle
bending of the plate surface.
To improve the anisotropy of materials. The yield limit of aluminum
2 sheet in longitudinal and transverse direction is often anisotropic,
which lead to higher scrap rate. This condition can be greatly improvedby stretching and straightening.
3 Eliminate the yielding platform and prevent the formation of slip line.
