急冷油泵泵体的铸造工艺设计
|
摘要
乙烯装置急冷油泵泵体铸件材质为高强度耐高温的马氏体不锈钢CA6NM。本文采用View-Cast铸造模拟软件辅助铸造工艺设计的方法,确定了合理的浇注及补缩系统。浇注的铸件通过均匀化退火,有效预防了CA6NM材料在铸造及清整过程中裂纹缺陷的产生,得到了符合质量要求的铸件,为急冷油泵国产化提供了质量保证。
Quenching oil pump for ethylene plant was made from high temperature resistant martensitic stainless steel CA6 NM. This paper introduces the casting process, crack defect prevention and production process of the quenching oil pump. The method of casting process design assisted by View-Cast casting simulation software ensures the determination of reasonable gating and risering system. Homogeneous annealing treatment of castings effectively prevents the crack defects during casting and cleaning. The castings produced meet the technical requirements of oil pump, which provides the quality assurance for the localization process of the quenching oil pump for ethylene plant.
