one-piece-forged,integrally forged

The basic requirements, detection method, and acceptance standard for supersonic detection of integrally forged solid rotor body for steam turbines have been presented, providing reference for detection of similar type products in power plants and in turbine manufacturing factor

随着冶炼、锻造及检验技术的提高,目前已有多台采用整锻式实心转子体的汽轮机投入运行或正在安装。

With a domestically-made 660 MW supercritical steam turbine generator unit serving as an object of study,the torsion rigidity of shafting specific structures(such as stepped shaft,wholly-wrought wheel disks) and its effect on torsion vibration were calculated and discussed as a major focus.

以某国产660 MW超临界汽轮发电机组轴系为对象,重点计算和讨论了轴系特定结构(如阶梯轴、整锻轮盘)的扭转刚度及其对扭振特性的影响。
