Abstract

The invention discloses a production method of a 5052-H32 aluminum alloy plate-strip. The production method mainly comprises the following steps: casting, saw-cutting, face-milling, heating, hot rolling, cold rolling, stable annealing and finishing, wherein in the hot rolling step, the finish rolling temperature of hot rough rolling is controlled at 370-450 DEG C, the finish rolling temperature of hot fine rolling is 320-350 DEG C, and the thickness of a hot rolling ingot can be determined according to the requirement on the thickness of a finished product; and in the cold rolling step, the thickness of the finished product can be achieved by performing cold rolling once, and the total machining rate is 20-45%. According to the production method disclosed by the invention, for a finished 5052-H32 product with the thickness of not less than 1.1mm, full annealing and intermediate annealing process steps of the hot rolling ingot can be eliminated, the production cycle can be shortened and the production cost can be reduced.
