Problems solved by technology

Those skilled in the art consider using cast-rolled billets instead of hot-rolled billets. However, compared with hot-rolled billets, cast-rolled billets have less uniform grain structure inside the base material, and the grain size is also larger than hot-rolled billets. It is not easy to obtain aluminum base materials that meet the requirements of deep processing

Abstract

The invention discloses a manufacturing method for a ceiling aluminum base material. A cast-rolled strip blank is coldly rolled, annealed, withdrawn and straightened as well as packaged in sequence, wherein in the cold rolling treatment process, the manufacturing method comprises the following steps: first, rolling the cast-rolled strip blank to a thickness of 6.5 mm, 4.5 mm, 3.0 mm and 2.2 mm in sequence; and then carrying out immediate annealing treatment on the 2.2 mm thick cast-rolled strip blank; and finally, rolling the cast-rolled strip blank treated through immediate annealing to a thickness of 1 mm. Experiments verify that a crystal grain structure in a finished product is more uniformr through selecting proper cold rolling pass distribution, a proper immediate annealing thickness and an annealing method, the bending performance of the finished product can satisfy machining requirements and a purpose of manufacturing the aluminum base material satisfying deep machining requirements by using the cast-rolled strip blank is achieved.

Description

technical field [0001] The invention relates to the technical field of metallurgy, and more specifically, relates to a production method of an aluminum substrate for a ceiling. Background technique [0002] The aluminum plate-based ceiling material has the advantages of high flatness, high strength, light weight, waterproof and fireproof, and has considerable advantages in size, shape, surface treatment and color, so this product is very popular in the market. Widely used in interior decoration, pre-decoration and other projects. [0003] At present, the ceiling base material is generally processed by hot-rolled billet, and the general process is: cold rolling-annealing-stretch leveling. [0004] Since ceiling products require further processing and bending on the surface of the base material, the requirements for the bending performance of the base material are extremely high. For this reason, hot-rolled billets are generally used in the cold-rolling process to meet the n...
