摘　　要：通过对上冠、下环、叶片铸件的充型过程及温度场变化进行模拟,确定合理的工艺方案。根据三峡铸件的标准确定三种铸件的内控化学成分,采用合理的造型工艺、熔炼工艺、浇注工艺、热处理工艺及加工工艺,得到符合标准的铸件。The reasonable process schemes were determined by simulating the filling process and temperature field variation for crown, band and blade casting. The internal chemical compositions of three kinds of castings were determined according to the standards of Three Gorges project. The castings quality can meet requirement of standards by reasonable molding process, smelting process, pouring process, heal treatment and processing technology.
