Production method of 5052-H22/32 aluminum alloy plate strip

The invention discloses a production method of a 5052-H22/32 aluminum alloy plate strip. The production method comprises the following production processes of: fusion casting, saw cutting, plane milling, ingot casting heating, hot rolling, finishing clipping and flattening, wherein in the hot rolling process, four-roller reversible hot rough rolling and hot continuous rolling by 3-5 standers can be used, wherein the start rolling temperature during hot rough rolling is 490-500 DEG C, the total rolling pass is controlled to 25 or 27 in the rough rolling process, the rolling speed is 100-140m/min and the finish rolling temperature during hot rough rolling is 400-490 DEG C; and the start rolling temperature during hot finishing rolling is 380-460 DEG C, the reeling speed during hot finishing rolling is 270-310m/min and the finishing rolling temperature is 280-302 DEG C. The production method disclosed by the invention has the capabilities of ensuring the product performance, shortening the production flow and saving the cost and can be used for directly producing an H22/32-state plate strip product with the finished-product thickness of 2.0-8.0mm through hot rolling.
