某大型轮机主轴法兰直径φ2.65 m，总长近10 m，锻件重达150 t，其规格超出水压机车间现有附具的工作范围，很难用传统锻造方法进行整体锻造生产。为此设计出一种新的锻造方法并对现有附具进行改造，最终成功锻造出形状和尺寸合格的大型轮机主轴锻件。

The main shaft of a large water turbine has a flange diameter ofφ2.65 m and is 10 m long. The weight of the main shaft forging is 150 t. Such large forging can not be made with the operational tools of the forging workshop and the monobloc forging is difficult to make with conventional forging operation. For this reason, a new forging process is designed and the operational tools are modified. With this effort, the large main shaft forging that has acceptable shape and dimensions is made successfully.
