The longitudinal internal stress is caused by the uneven tension inside the rolled piece, which makes the tension applied on the width of the rolled piece upward difference. The so-called target strip shape curve refers to the curve formed by the tension difference along the strip width direction under the external tension of the strip. It not only reflects the real shape of strip, but also is an important means of shape control in modern rolling mill. In daily production, the commonly used curves are mainly flat curve, sine curve and cosine curve.
The sine curve warping on both sides of the bottom is beneficial to reduce the probability of strip fracture during rolling, and is suitable for the production of cold-rolled sheet. Both sides of the cosine curve are warped, and the middle of the two sides of the rolled piece is tight and loose, which is suitable for the production of blanks or thick plates. Flat curve is suitable for the production of special sheet or aluminum foil rolling.
The above is the "selection of target aluminum plate shape curve" introduced by aluminum plate manufacturers. To learn more about aluminum plate information, please visit the website: http://www.jndclyxgs.com
