多曲面高载荷立柱铸造工艺设计

Casting Process Design of High Load Rudder Tube with Multi-curved Surface

通过对多曲面高载荷立柱铸造工艺设计研究,采用分段铸造而后组焊的工艺降低了铸造难度;同时,通过对铸造过程中造型、熔炼及浇注、热处理、组焊、质量检验和缺陷修补等工艺过程的控制,解决了铸型的注填困难及铸件容易产生缩孔、气孔、砂眼和夹杂等缺陷的工艺难题,形成了一套安全可靠的立柱铸造工艺流程。结果表明,按照本工艺铸造生产的立柱铸件质量满足设计和使用要求。

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.
