preparation example Construction

[0033] Such as figure 1 Shown is a method for preparing a 5182-O state aluminum alloy plate for automobiles, comprising the following steps:

[0034] A. Ingredients: The 5182 aluminum alloy raw materials are batched according to the weight percentage, and the mass percentage ratio of each element of the aluminum alloy raw materials is as follows:

[0035] element Si Fe Cu mn Mg Cr Zn Ti Ni Impurities Al content 0.06 0.179 0.05 0.20 4.8 0.1 0.05 0.1 0.1 0.03 margin

[0036]B. Melting and casting: Add the prepared aluminum alloy raw materials into the smelting furnace and mix them evenly to melt them into liquid aluminum alloys. After standing still, refining, slag removal, online degassing, and filtering processes, the liquid aluminum alloys are melted and cast into aluminum alloys. Ingot casting, adding Al-5Ti-B wire refining agent during the refining process of molten aluminum, using double rotors for online degassing, and t...

Abstract

The invention belongs to the technical field of aluminum alloy manufacturing, and relates to a 5182-0 aluminum alloy sheet preparation method for automobiles. Aluminum alloy raw materials are preparedfrom the components in percentage by mass: namely 0.01-0.08% of Si, 0.15-0.30% of Fe, 0.01-0.1% of Cu, 0.10-0.30% of Mn, 4.5-5.0% of Mg, less than or equal to 0.1% of Cr, less than or equal to 0.05%of Zn, less than or equal to 0.1% of Ti, less than or equal to 0.1% of Ni, less than or equal to 0.05% of a single impurity, less than or equal to 0.15% of total, and the balance of Al. Aluminum alloycoils cold rolled to intermediate pass in cold rolling process are annealed and insulated at 320 DEG C for 2 h, wherein the annealing process of finished aluminum alloy coils is passed in a single layer mode in a continuous air cushion annealing furnace, the coils are blown to suspend in the furnace through hot air, and the problems that most parts of the local deformation of aluminum alloy sheets are cracked during the stamping deformation due to the uneven inner grain structure of aluminum alloy sheets prepared by existing aluminum alloy sheet preparation process are solved.

Description

technical field [0001] The invention belongs to the technical field of aluminum alloy manufacturing, and relates to a method for preparing a 5182-O aluminum alloy sheet for automobiles, in particular to a method for preparing a 5182-O aluminum alloy sheet for automobiles with excellent stamping performance. Background technique [0002] Traditional automotive materials are mostly processed by deep-drawn steel sheets. In recent years, with the development of automotive lightweight technology, the degree of aluminum alloying of auto parts is increasing day by day. Taking plates as an example, the application of aluminum alloy plates in automobiles is mainly divided into outer panels and inner panels. As the automobile industry pays more and more attention to the beautiful appearance and smooth lines of the car body, all of these need to be realized by stamping, which has extremely high requirements on the forming performance of the material. [0003] 5000 series aluminum allo...
