1. The plate shape concept of china 5052 aluminum plate

1. Plate shape usually refers to the straightness of the plate and strip, that is, whether there are waves, warpage, side bending and buckling in each part of the plate and strip.

2. Plate shape is an important quality indicator of plate and strip. The quality of the plate shape depends on whether the longitudinal extension of the strip in the width direction is equal during rolling, the uniformity of the cross-sectional thickness of the blank before rolling, the roll shape and the actual roll gap formed by the bending deformation of the roll during rolling. shape etc. It can be seen that the plate shape and the lateral thickness accuracy are closely related.

2. Definition of wave in china 5052 aluminum plate

The wave in the shape of the china 5052 aluminum plate is caused by the inconsistent extension of the width of the plate and strip to the longitudinal direction of each part during rolling. When the two sides of the plate and strip extend more than the middle, symmetrical bilateral waves will be generated; on the contrary, if the middle of the strip extends more than the two sides, middle waves will be generated; if the amount on both sides is unequal, the side with the larger depression will be extended more, then a single wave will be generated. Side wavy or side bend (sickle). When the rolled piece leaves the roll outlet, it goes up or down, or bends in an arc shape in the width direction, which is called warpage.
