specific Embodiment approach 1

[0020] Specific implementation mode 1: In this implementation mode, the leveling method of the aluminum alloy thick plate after quenching is implemented according to the following steps:

[0021] 1. Heat the aluminum alloy thick plate to 400-550°C, heat it, and quench it out of the furnace to obtain the quenched aluminum alloy plate;

[0022] 2. Measure the unevenness of the aluminum alloy plate after quenching (0-10mm / m);

[0023] 3. The quenched aluminum alloy plate that needs to be leveled adopts the following plate shape correction methods according to the thickness and unevenness:

[0024] (1) For the quenched aluminum alloy sheet, when the transverse unevenness is ≤3.5mm / full width, it is directly stretched by a stretching machine;

[0025] (2) For the thickness of the aluminum alloy sheet after quenching ≤ 40.0mm, when the transverse unevenness is greater than 3.5mm / full width, the aluminum alloy sheet after quenching is first straightened by a straightening machine, a...

Abstract

The invention discloses a leveling method for a quenched aluminum alloy thick plate, belongs to the technical field of aluminum alloy processing, and aims to solve the plate shape problems of bending, warping, dead bending, out-of-limit unevenness and the like which are easy to occur after the aluminum alloy thick plate is quenched. The leveling method comprises the following steps of 1, carrying out heat preservation and quenching on the aluminum alloy thick plate; 2, measuring the unevenness of the quenched aluminum alloy plate; and 3, adopting different plate shape correction methods for the leveled and quenched aluminum alloy plate according to the difference of the thickness and the unevenness. By means of the leveling method, three methods of rolling mill straightening, straightening machine straightening and stretching are adopted to level the shape of the quenched aluminum alloy thick plate, the treated plate does not have the plate shape problems of bending, warping, dead bending, out-of-limit unevenness and the like, and the plate flatness problem is solved in a rolling mill pass reduction mode. According to the leveling method, the transverse unevenness of the aluminum alloy plate is smaller than or equal to 3 mm / full width, the transverse unevenness after stretching is smaller than or equal to 3 mm / full width, and the longitudinal unevenness after stretching is smaller than or equal to 3 mm / full length.

Description

technical field [0001] The invention belongs to the technical field of aluminum alloy processing, and in particular relates to a leveling method for aluminum alloy thick plates. Background technique [0002] Aluminum alloy has low density, but relatively high strength, and has excellent electrical conductivity, thermal conductivity and corrosion resistance. It is the most widely used non-ferrous metal structural material in the industry. It has been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industry. Compared with other aluminum alloy types, aluminum alloy thick plates account for a higher proportion of aluminum alloy applications, and are the main supply form of aluminum alloys. [0003] For aluminum alloy thick plates, especially thick alloy plates that can be strengthened by heat treatment, the plate shape after quenching has always been an important problem that needs to be solved. After quenching, aluminum alloy ...
