The plate shape of china 5052 aluminum plate usually refers to the straightness of the plate and strip, that is, whether there are waves, warping, side bending and scooping in each part of the plate and strip. Plate shape is an important quality index of plate and strip. The quality of the plate shape depends on whether the longitudinal extension in the width direction of the plate and strip is equal during rolling, and the uniformity of the cross-sectional thickness of the billet before rolling.

The roll shape and the actual roll gap shape formed by the bending deformation of the roll during rolling, etc. It can be seen that both the plate shape and the transverse thickness accuracy are closely related. The definition of waves in china 5052 aluminum plate plate shape is caused by the inconsistency of the longitudinal extension of the width of the plate and strip to each part during rolling.

When the extension of the two ends of the strip is greater than the middle, symmetrical bilateral waves will occur; on the contrary, if the extension of the middle is greater than the two ends, the middle waves will occur; Side waves or side bends (sickle). When the rolled piece leaves the exit of the roll, it goes up or down, or bends in an arc along the width, which is called warping.

Representation method of china 5052 aluminum plate shape Quantitative expression of shape is not only the need to measure shape quality in production, but also the need to study shape control and complete shape control. At present, countries have different ways of expressing it according to the purpose of use. One of the ways to express the shape of China 5052 aluminum plate is to cut a section of the strip and place it on the platform.
