Embodiment Construction

[0013] The composition and weight percentage of the embodiment of the material of the present invention are: Si 0.22-0.28%, Fe 0.42-0.50%, Cu 0.05%, Mn 0.15-0.20%, Mg 0.03%, Cr 0.05%, Zn 0.10%, Ti 0.04 %, Al balance, each component is smelted into an alloy.

[0014] Embodiments of the method of the present invention go through the following steps successively:

[0015] 1. Smelting, smelting the raw materials of the above ingredients and proportions, the smelting must be degassed and slag removed, and the electromagnetic stirring technology is used to stir fully and evenly; the temperature of the guide furnace is controlled within the range of 750±5°C; hydrogen The content is controlled below 0.15ml / 100g.Al, and double-stage filtration is adopted to ensure the quality of the melt;

[0016] 2. Casting and rolling

[0017] During casting and rolling production, the rotary blowing method is used for on-line degassing, the filter adopts 30PPi+50PPi double-stage filtration, the mo...

Abstract

The present invention belongs to the technology for manufacturing aluminum alloy material and an aluminum foil, relating to an aluminum foil for an air conditioner and a method for manufacturing the aluminum foil for air conditioner. The aluminum foil for air conditioner comprises the following constituents and percentage by weight: 0.22-0.28% of Si, 0.42-0.50% of Fe, 0.05% of Cu, 0.15-0.20% of Mn, 0.03% of Mg, 0.05% of Cr, 0.10% of Zn, 0.04% of Ti and the rest being Al; each constituent is melted into an alloy. On the basis of existed alloys, the method integrates the advantages of the existed air conditioner foils; due to the cooperation with the technological method of the present invention, the produced aluminum foil has the advantages of high extending efficiency, high turn-edge height and difficult breaking and the like. The method is also applicable for the high speed punching to improve the production efficiency.

Description

technical field [0001] The invention belongs to the manufacturing technology of aluminum alloy materials and aluminum foils, and relates to an aluminum foil material for air conditioners and a manufacturing method of the aluminum foils for air conditioners. Background technique [0002] At present, all aluminum alloys used to produce air-conditioning foils on the market are generally 1200, 1100, 8011, and 1030 alloys. The use of 1200, 1100, 8011 alloys to produce air-conditioning foils has the advantages of good elongation and high flanging height, but due to the softness of these alloys, the speed in the punching process is relatively slow and the production efficiency is low; the use of 1030 alloys to produce air-conditioning foils , which has very good rigidity, can adapt to high-speed punching machines, and improves production efficiency, but because of the problem of its own alloy ratio, the alloy product has a low flanging height during the punching process and is easy...
