Abstract

The invention provides a method for manufacturing a No. 3004 aluminum alloy material used for a shutter, which maintains good surface quality of an aluminum strip, fine grain structure, leveled profile shape of a finished product, uniform thickness and high dimension precision through optimized casting, cold rolling and intermediate annealing. Moreover, the forming property and the camber stability accord with the requirements of the shutter product, and simultaneously the method has simple manufacturing technique, short production period, low cost and obvious productivity effect, and can use a cast and rolled plate blank to produce the aluminum material with good mechanical property, profile shape and surface quality for the shutter to meet the user requirements.

Description

technical field [0001] The invention relates to a manufacturing method of an aluminum alloy material, in particular to a manufacturing method of a 3004-grade aluminum alloy material for shutters. Background technique [0002] Aluminum alloy shutters are favored by the market due to their high hardness, beautiful appearance and durability, and the market demand is increasing. [0003] At present, the 3004 grade aluminum alloy materials for shutters are mainly produced by the hot rolling-cold rolling method. Although the product quality is good, the process is long, the cost is high, the yield is low, and the equipment investment cost is high. The product price is significantly higher than that of ordinary aluminum alloys of the same type. Strip products. SUMMARY OF THE INVENTION [0004] Aiming at the above defects, the present invention provides a method for manufacturing 3004 grade aluminum alloy material for blinds, through optimized casting, cold rolling and intermedia...
