According to the structural characteristics of large and complex round-table titanium alloy castings

two kinds of casting processes were designed to optimize the casting process combined with simulation

of which the vertical bottom injection process was the satisfactory.Graphite mold casting process was used for production verification

and high-quality castings were obtained

of which the size structure

surface quality and internal quality all meet the requirements of Class I in GJB2896 A-2007.
