the invention relates to a straightening control device for aluminum plate, strip and foil formats and a use method thereof.
The background technology is as follows:
the aluminum strip is affected by the original blank plate shape, pass processing rate, tension, rolling speed, bending roller, cooling lubrication and other factors of the rolled piece in the cold rolling process, and the cold rolled aluminum strip extends differently along each part of the strip width. It is envisaged that the strip may be divided into a plurality of longitudinal strips, and the variation in the amount of depression on any one strip will cause a variation in the longitudinal extension of that strip, while affecting the deformation of the adjacent strip. Therefore, when the reduction is unevenly distributed, the respective strips are correspondingly unevenly extended, thereby generating internal stress between the strips. When the internal stress of the strip is sufficiently high, a buckling, i.e. waviness, of the strip is caused. The common cold-rolled strip wave is divided into three conditions of medium wave, two-rib wave and side wave according to the distribution position of the common cold-rolled strip wave. The medium wave is generated because the middle part of the strip longitudinally extends more than two edge parts, and is influenced by the internal stress of the strip to form the medium wave, and the rest are similar.
After cold rolling, the strip usually has a plurality of defects of wave coexistence due to different longitudinal extension, and in order to eliminate the defects, a finishing procedure usually adopts a straightening measure to improve the incoming material model.
The traditional stretch bending straightener is only suitable for the condition that the strip after cold rolling has a good plate form (namely the I value of the incoming material plate form is less than or equal to 40I), and can realize plate form straightening relatively easily, and the I value of the plate form after straightening is less than or equal to 6I; however, when the I value of the incoming material is larger than 40I, the straightening mechanism is difficult to achieve the model target with the I value smaller than or equal to 6I.
