Recently, Shaanxi Tiancheng Aviation Materials Co., Ltd. (hereinafter referred to as “Tiancheng Aviation Materials”) broke through the production problem of large-sized cylinder forgings and successfully delivered a titanium alloy cylinder forging with a length of more than 8 meters and a net weight of more than 3000Kg for nuclear power. The titanium barrel adopts a brand-new process design, and the wall thickness is only 35mm. It is currently the largest high-strength thin-walled titanium alloy barrel forging in China.
High-strength thin-walled titanium alloy tube forgings
This cylinder forging is mainly used in a nuclear power project, which has extremely high requirements for product strength, density, heat and corrosion resistance, and because of its large size, how to solve the problem of large temperature difference in the overall forming process, low terminal temperature and uneven stress and strain distribution Maintaining uniform organization, performance and wall thickness before and after the barrel forging is a technical difficulty in the early stage of the project planning.
