Diversion of nuclear reactor components used in the manufacturing method of confining plates

The present invention provides a method of manufacturing a deflector hoarding an in nuclear reactor components used. After refining the ingot is heated to 950 ~ 1150 ℃ placed on a hydraulic press forging and ring blanks made by punching the indentation cavity preheated to 250 ~ 350 ℃, after applying a release agent to set on the mandrel, and then the annular sleeve blank on the indentation cavity ring blank with hydraulic platform under the platform for mobile supremacy reaming, indentation, when the inner diameter of the annular blank occurs when small steps to prepare a ring-shaped blank. After the annular blank heated to 950 ~ 1150 ℃, placed on a mandrel ring rolling machine provided reaming the cavity. Turn the ring blank ring rolling machine reamer to a predetermined size, by the mechanical properties, microstructure and corrosion-resistant, high-pressure test, and then by a small margin machined deflector that is made of hoarding. Deflector panels made of the method, the fiber direction with forging shaped distribution, small machining allowance, mechanical properties and service life, with a high temperature, high pressure and corrosion resistance, and low cost.
