[0088] Chemical Composition of Materials (WT%): Table 7

[0089]

[0090] (1) Calculate and prepare the materials according to the above ingredients, put them into the melting furnace for melting, the melting temperature is 730-750°C, and after refining (using Na-free covering agent + composite material KCl+GaCl+MgCl 2 , KCl, GaCl, MgCl 2The mass ratio is 1:1:1. , Na element is controlled below 5ppm, the gas uses Ar, SNIF rotary degassing device. After removing slag, stirring, analyzing and adjusting the composition, it enters the static furnace, the static temperature is 645°C, degasses, removes slag (using a ceramic tube filter), and then enters the casting machine after adding an appropriate amount of Al-5Ti-1B wire into the molten aluminum. Cast into ingots, casting temperature is 587°C. The casting speed is 40mm / min. The surface of the ingot is milled. Single rotor degassing. The grain refiner adopts AlTiC refiner.

Abstract

The invention provides a preparation method of an aluminum alloy for an aerosol bottle cap. The method comprises the steps of S1, preparing a cast ingot through alloy components based on the mixing ratio; S2, milling the cast ingot; S3, uniformly thermally processing the cast ingot; S4, performing hot rolling on the cast iron to obtain a blank; S5, performing cold rolling to the blank which is subjected to hot rolling until the intermediate annealing thickness is reached; S6, washing the surface with weak alkali; S7, completely recrystallizing and annealing the middle; S8, performing pass rolling on a finished product; S9, stably chemically processing the finished product; and S10, stretching and bending and correcting back roll. According to the method, the Na content is effectively decreased based on the component mixing ratio and the technical method; the range of Na element which easily causes Na embrittlement in a high-magnesium alloy is avoided, and thus the problem of Na embrittlement is solved; and meanwhile, the component fluctuation is well controlled, and the problem that the magnesium element easily results to slag inclusion is solved; and meanwhile, the problem of liquid leaking caused by impurities adhering to the surface can be solved by a special weak alkali washing technology in the middle process; and the produced aluminum alloy for the aerosol bottle cap is high in stability in batch.

Description

technical field [0001] The invention belongs to the technical field of aluminum alloy preparation, and more specifically relates to a method for preparing an aluminum alloy for an aerosol bottle cap. Background technique [0002] At present, bottled aerosol cans are widely used due to their portability / smallness and practicality. The can lid is subject to relatively high pressure. At present, the aerosol bottle body and bottle cap are made of various materials such as PVC plastic / tinplate / aluminum. PVC plastic is generally easy to be injection molded, but because the aerosol bottle is a pressurized liquid, The overall strength of PVC plastic is low, and it is easy to crack during use to cause liquid leakage and be scrapped. Therefore, the utilization rate in the industry is not high, and the strength of tinplate is relatively high. However, due to the limitation of processing technology, the material of the manufactured aerosol bottle needs to be thicker. Material, plus the...
