Embodiment 1

[0048] 1. After obtaining the low residual stress ingot, carry out homogenization heating to reach the rolling conditions, and the temperature of the ingot is not allowed to have an obvious temperature gradient (the temperature error is less than 5 °C).

[0049] 2. Using a special rolling process, equal reduction, equal rolling force, and horizontal roll shape disturbance, during the rolling process, the ingots extend uniformly in the longitudinal direction, and at the same time, they extend uniformly in the longitudinal direction at different points in the transverse direction. The amount of compression deformation is consistent, which reduces the inconsistency of compressive stress caused by unevenness in the rolling process. The subsequent process cannot be eliminated or the inconsistency after elimination, resulting in inconsistency of sheet stress inside the sheet. In a reasonable rolling process, the roll disturbance is well controlled, so that the ingot structure flows u...

Abstract

The invention discloses a preparation method of an aluminum alloy plate. The steps of the method include: S1: obtaining an ingot; S2: uniformly heating the ingot, so that the temperature deviation of the whole ingot is less than 5°C; S3: correcting The ingot processed by S2 is rolled to obtain a plate of required thickness; S4: annealing the plate to make the internal organization of the plate consistent in size and orientation. The invention controls the internal compressive stress and the stress value of each point of the uniformly deformed plate generated during the processing of the aluminum alloy material to be close to a small deviation, so as to meet the demand for the aluminum alloy plate in the production of high-end equipment.

Description

technical field [0001] The invention relates to a preparation method of an aluminum alloy plate. Background technique [0002] At present, the application of aluminum alloys in the industry is increasing year by year, but the quality of the finished products is uneven. However, high-end aluminum alloy materials mainly rely on imports, and it is imperative to produce high-quality aluminum alloy sheets. With the continuous progress and development of science and technology, aluminum alloy profiles continue to develop in the direction of large-scale, integrated, uniform and high-quality structure and properties. Therefore, the preparation of high-performance aluminum alloys has become a focus of attention. [0003] Disadvantages of the traditional process: the structure and composition of the ingot is complex, the distribution of the second phase is uneven, and the grain size in the ingot is different, which leads to the large internal macro stress of the ingot. Intragranula...
