Abstract

The invention relates to a preparation method of an aluminum alloy. The preparation method comprises the following steps of 1, preparing raw materials; 2, smelting raw materials in a smelting furnace,placing aluminum in the lowermost layer when the raw materials are put into the smelting furnace, smelting and melting the raw materials of aluminum, silicon, copper, yttrium, silicon, chromium, carrying out temperature measurement on the mixture, adopting a slag removal device to remove dross on the surface of a molten liquid when the temperature reaches 825-855 DEG C, then adding magnesium according to the weight ratio, stirring the molten liquid in the furnace for 10-15 minutes by using a stirring device, then using a metallurgical slag removal device to remove slag again, then adding theraw materials of cadmium, ytterbium, samarium and terbium, stirring for 20-30 minutes, using a bell jar to press the hexachloroethane to carry out degassing and deslagging, carrying out standing for 20-30 minutes, carrying out slag removal and filtration to obtain an aluminum alloy melt; 3, finishing; 4, casting and extruding and forming; 5, homogenizing annealing treatment; 6, cooling; and 7, carrying out heat treatment. According to the method, the mechanical property of the alloy is improved by virtue of a reasonable extrusion and heat treatment process, so that the tensile strength of thealuminum alloy reaches more than 370 MPa.

Description

technical field [0001] The invention relates to the technical field of aluminum alloy manufacturing, in particular to a method for preparing an aluminum alloy. Background technique [0002] Aluminum alloy has a series of excellent properties, and aluminum ranks second only to steel in the application of metal materials. At present, the world's aluminum consumption (primary aluminum and secondary aluminum) has exceeded 36 million tons, while the consumption of aluminum has reached more than 26 million tons, which is used for transportation (including railway vehicles, automobiles, motorcycles, bicycles, etc.) , motorboats, speedboats, etc.) account for more than 36% of the aluminum, the aluminum used in the construction industry accounts for about 21%, and the aluminum used in the packaging industry accounts for about 20%. With the continuous development of science and technology, especially in high-tech fields, the quality requirements for aluminum alloy products are gettin...
