Abstract
This article mainly discusses the key points of anti gravity casting technology for large thin-walled aluminum alloy flat parts.Firstly,the important applications and challenges of aluminum alloy thin-walled flat parts in the aerospace field were introduced.Secondly,the application of simulation technology in anti gravity casting was introduced.Subsequently,the problems encountered in traditional casting processes were analyzed,including unstable material properties,structural defects,uneven wall thickness,and complex processing techniques.Subsequently,the principles and applications of new anti gravity casting technologies such as low-pressure casting,vacuum suction casting,differential pressure casting,pressure regulating casting,injection casting technology,isothermal injection casting technology,and liquid metal electromagnetic suspension technology were introduced in detail.Finally,the research results of this article are summarized,and the direction and challenges of future research on anti gravity casting technology for large thin-walled aluminum alloy flat parts are pointed out.The research results of this article are of great significance for improving the casting quality and efficiency of large thin-walled aluminum alloy flat parts,and promoting the development and innovation of casting technology.关键词
