experiment example 1
[0141] Such as figure 2 As shown, it is a schematic view of the structure of an aluminum alloy casting with a cross-sectional dimension of 1170×821 and an axial dimension of 1200 mm, which is integrally cast and processed from aluminum alloy. The figure includes the end 1 of the aluminum alloy casting, the inner cavity 2 of the aluminum alloy casting and the shell 3 of the aluminum alloy casting, wherein the end 1 of the aluminum alloy casting includes a half end face, an end face connecting hole, a high-precision hole system and an end face.
[0142] Such as image 3 shown, for figure 2 A schematic diagram of the local structure of the inner cavity of the aluminum alloy casting, which includes: the inner cavity surface 21 of the aluminum alloy casting and the inner cavity mounting part 22 of the aluminum alloy casting, and the inner cavity surface 21 of the aluminum alloy casting has multiple inner nets of different sizes Grid curved surface, its thickness is 2.5mm ~ 3.5m...
