1000MW半转速核电汽轮机高中压缸制造技术研究

The Manufacture & Technology Research for 1000MW Half-speed Nuclear Power HIP Casing

1000MW半转速核电机组的特点是结构尺寸大、转速低。文章以东方汽轮机有限公司与法国ALSToM合作的1000MW等级半转速核电机组为例,较为详细地介绍了核电汽轮机重要的静子部件高中压外缸的机械加工工艺方案、数控加工程序、产品试制过程,总结出了一套切实可行的核电高中压外缸制造技术。

1000MW half-speed nuclear power unit has character of large size structure and low revolution. Based on 1000MW half-speed nuclear power unit cooperatively produced by Dongfang Turbine Co., Ltd. and Alstom, this theme explains the mechanical technology plan of outer casing NC machining program, product manufacture tests and summarizes set of practicable manufacture technology of nuclear power unit outer casing.
