Abstract

The invention discloses a forming device and method for aluminum alloy structure refining. The device comprises a slope serpentine channel, a feeding funnel, a vibration platform and a matched mold. The angle of the slope serpentine channel is 30-50 degrees, and the length of a slope is 1000mm. The number of bends is 2-6. The angle of each bend is 100-150 degrees, and the vibrational frequency is100-200Hz. According to the forming technology, the serpentine slope and the vibration technology are combined, and the aluminum alloy structure can be effectively refined. Aluminum alloy melt is poured into the feeding funnel after refining and drossing. The melt is poured into the metal mold connected with the vibration casting platform after passing through the slope serpentine channel with a certain tilted angle, and then is cooled, consolidated and formed at a certain vibrational frequency.

Description

technical field

[0001] The invention relates to an aluminum alloy forming process, in particular to a forming device and method for refining the structure of an aluminum alloy. Background technique

[0002] Aluminum and its aluminum alloys have the advantages of easy processing, low density, high strength, good electrical conductivity and corrosion resistance, and have broad application prospects. Aluminum products are widely used in the fields of transportation, machinery and aviation industry. Aluminum has become the most consumed non-ferrous metal in the world today. The total amount of aluminum alloy scrapped by aluminum products every year accounts for about half of the total demand in the global aluminum market. The efficient recycling and reuse of scrap aluminum alloy is of great significance to the development of the aluminum alloy industry. However, a large amount of impurity elements are likely to be mixed in the recycling and remelting process of recycled alumin...
