Abstract

The invention relates to the technical field of aluminum alloy preparation, in particular to a large-diameter 7005 aluminum alloy round ingot and a preparation method thereof. The large-diameter 7005 aluminum alloy round ingot and the preparation method thereof are provided in order to overcome the defects that the prior ingot has high crack tendency, serious component segregation and small dimension specification. The method for preparing the aluminum alloy round ingot comprises the processes of fusant treatment, gas curtain casting and homogenizing annealing. The method improves the comprehensive performance of aluminum alloy, can save the energy consumption and reduce the discharge of pollutants to achieve the aim of energy conservation and emission reduction, and has significant social benefit and environmental benefit; and simultaneously, the large-diameter 7005 aluminum alloy round ingot and the preparation method can satisfy the major requirements by industrial segments in China, and save a large amount of purchase foreign exchanges of the 7005 aluminum alloy round ingot for the country.

Description

technical field

[0001] The invention relates to the technical field of aluminum alloy preparation, in particular to a large-diameter 7005 aluminum alloy round ingot and a preparation method thereof. Background technique

[0002] 7005 aluminum alloy belongs to the Al-Zn-Mg series weldable and heat-treatable alloy, which has been widely used in various industrial sectors at home and abroad in recent years, such as construction, bicycle, automobile, rocket manufacturing and so on. The air curtain casting process of aluminum alloy round ingot is one of the most advanced technologies in the world today. It has been widely used and developed rapidly because of its advantages of high production efficiency, low labor intensity, good ingot quality and high yield. Products produced by the existing air curtain casting process still have problems such as high alloy ingot crack tendency, serious composition segregation, high hydrogen content, high slag content, and high temperature. In ...
