Background

In the thermal power generation industry, the rotating shaft which is overweight and overlong is required, and the difficulty of turning is high due to the large diameter, the long length and the heavy weight of the rotating shaft. For example, the length of the rotating shaft in a large power plant may be about 10 meters, the maximum diameter may exceed 0.7 meters, and the operating temperature may be between 360 degrees and 550 degrees. Accordingly, such spindle shafts are typically made of 316 stainless steel.

Although 316 stainless steel has the advantages of corrosion resistance, high temperature resistance, extremely high-temperature strength and the like, the 316 stainless steel has poor cutting performance, so that cutting processing is difficult, and the processing precision of a processed shaft is not easy to guarantee. Particularly, when the thimble is used for supporting and positioning the rear end of the shaft, the middle position of the shaft is easy to form downward arc-shaped bending deformation under the action of self gravity, so that the coaxiality of the shaft is difficult to ensure during turning, and even the shaft rolls during turning.
