Embodiment Construction

[0012] A kind of manufacture method of aluminum alloy packaging bottle material is as follows:

[0013] The alloy components are Fe: 0.75 parts, Si: 0.7 parts, Cu: 0.75 parts, Mn: 0.06 parts, Mg: 0.45 parts, Zn: 0.35 parts, Ti: 0.03 parts and the balance AL, totaling 100 parts. If there are impurities, the total amount of impurities: ≤0.12 parts, and the content of individual impurities <0.03 parts.

[0014] 1. Preparation-melting aluminum alloy, adding components by weight to the melting furnace, melting at 720-740°C, and casting aluminum alloy ingots at 715-725°C after all the charge is melted.

[0015] 2. Face milling: face milling of the aluminum alloy ingot, the amount of face milling on one side is required to be ≥ 12mm, the thickness difference between the two sides is ≤ 2.6mm, and the roughness of the milling surface is required to be 0.06-0.15mm.

[0016] 3. Heating: Heat the aluminum alloy ingot after face milling to 510-540°C for 15-20 hours, heat it for 7-10 hours...

Abstract

The invention provides a manufacturing method of an aluminum alloy packaging bottle material. The alloy comprises the following components in percentage by weight: 0.75-0.80% of Fe, 0.60-0.75% of Si, less than 0.9% of Cu, 0.04-0.11% of Mn, less than 0.06% of Mg, less than 0.04% of Zn, 0.02-0.04% of Ti and the balance of Al, totaling 100%. The manufacturing method comprises the following steps: proportionally melting alloy elements, evenly mixing, and casting into a blank ingot; carrying out face milling on the aluminum alloy blank ingot, wherein the single-side face milling quantity is greater than or equal to 12mm, the thickness difference between the two sides is less than or equal to 2.6mm, and the face milling roughness is 0.06-0.15mm; heating the aluminum alloy blank ingot subjected to face milling to 500-560 DEG C within 15-20 hours, keeping the temperature for 6-10 hours, and discharging; rolling the heated aluminum alloy blank ingot in a rolling mill, wherein the thickness of the aluminum alloy blank ingot is distributed by 17-22 passes, and the temperature after hot rolling is kept at 280-320 DEG C; carrying out cold rough rolling by 5-6 times until the thickness is 35-45m, and carrying out interannealing in an annealing furnace; carrying out cold finish rolling on the annealed coil until the thickness of the finished product is 0.17-0.21mm, and selecting the extensibility according to the size and shape to carry out stretch bending and straightening; and cleaning and trimming the straight coil with a cleaning machine, and finally, cutting with cutting equipment according to the technological requirements.

Description

technical field [0001] The invention belongs to the technical field of nonferrous metal processing, and in particular relates to a method for manufacturing aluminum alloy packaging bottle materials. Background technique [0002] In recent years, with the development of food packaging technology, aluminum cans made of aluminum alloy plates with high tensile strength are used more and more in the packaging of beverages such as beer and carbonated drinks. The cans made of this material are stable in performance, do not squeeze or deform, and are easy to transport and carry. However, the production cost of this material is relatively high, which is not cost-effective for manufacturers. For packaging general food, such as candy, tea, and moon cakes, it does not need such a high tensile strength, and tinplate is used as the packaging material. Studies in recent years have shown that tinplate materials contain toxic components such as arsenic and lead, which are harmful to human ...
