Abstract：
Through the research on the casting process design of high load rudder tube with multi-curved surface, the technology of subsection casting and then assembly welding was adopted to reduce the difficulty of casting. At the same time, through to the casting process of molding, melting and casting, heat treatment, compound, quality inspection and defects repair process control, to solve the injection mold filling difficulty and easy to produce castings defects such as shrinkage cavity, porosity, sand holes and inclusions of technical problems, a set of safe and reliable stud casting process was formed. The results show that the quality of rudder tube castings produced by this process can meet the design and application requirements.
