Abstract

The invention belongs to the technical field of aluminum alloy manufacturing, and relates to a preparation process of aluminum alloy 5083 with high bending performance. The preparation process includes cutting and milling ingots of aluminum alloy 5083, sending the cut and milled ingots of aluminum alloy 5083 to a heating furnace, heating at the temperature of 54 DEG C for 6 hours, cooling to the temperature of 500 DEG C, holding the temperature for 2 hours, discharging and performing hot rolling until the thickness of the aluminum alloy sheets is 10.0mm under the finishing rolling temperatureof 320 DEG C, naturally cooling the hot-rolled aluminum alloy sheets to the room temperature, performing cold rolling until the thickness of the aluminum alloy sheets ranges from 3.0 to 8.0 mm with the cold rolling rate ranging from 20% to 70%, annealing at the temperature of 260-340 DEG C for 2 hours after cold rolling, straightening to obtain 5083-O type aluminum alloy sheets. The preparation method has the advantages simple processing and low energy consumption; the finished product has high bending processing performance and wide application range.

Description

technical field [0001] The invention belongs to the technical field of aluminum alloy manufacturing, and relates to a preparation process of a 5083 aluminum alloy with high bending performance, in particular to a preparation process of a 5083-O state aluminum alloy plate. Background technique [0002] Due to its excellent comprehensive performance, aluminum alloys are widely used in vehicle transportation, shipbuilding and other fields to replace steel with high weight to achieve the purpose of light weight, energy saving and emission reduction, thereby improving energy utilization. 5083-O aluminum alloy is used as the material of the ship's cable rack. While reducing its own weight, the 5083 aluminum alloy has the advantages of high strength and good corrosion resistance, which makes it perform better in the corrosive marine environment. Although the existing technology has used 5083-O aluminum alloy to replace steel, the technology of manufacturing cable racks from steel i...
