Abstract

The invention discloses a method for manufacturing an end socket of a voltage stabilizer for nuclear power. The integral end socket is subjected to hot stamping deep drawing by a 16MND5 low-alloy steel plate, and is subjected to heat treatment of normalizing and tempering to form the end socket, which is reliable in quality, accurate in size and high in mechanical property, of the voltage stabilizer for nuclear power. In the method, the weight of the end socket manufactured by the low-alloy steel plate can be reduced by about half compared with that of the end socket manufactured by forging piece materials, the manufacturing period is short and the cost is reduced greatly.

Description

Technical field:

[0001] The invention relates to a pressure vessel, in particular to a method for manufacturing a nuclear power voltage stabilizer head. Background technique:

[0002] The voltage stabilizer is one of the important equipment of nuclear power plants, and its safety level is Class I. At present, the head of the voltage stabilizer of the nuclear power plant built in my country is forged into a flat plate, and then hot stamped and deep drawn. Not only the manufacturing cycle is long, but also the manufacturing cost High, the shape, size and quality of the head are difficult to reach a high level. Invention content:

[0003] The purpose of the present invention is to avoid the existing technical problems and provide a method for manufacturing the head of a voltage stabilizer for nuclear power with reliable quality, precise size and low cost.

[0004] The technical scheme of the present invention is: the 16MND5 low-alloy steel plate is processed according to the ...
