Problems solved by technology

[0003] With the rapid development of China's domestic nuclear power plants, the demand for nuclear power heads is also increasing. If such heads are imported from abroad, it will inevitably affect the development speed of nuclear power plants. It will also be restricted by the foreign environment, and the processing time will be long. High cost of outsourcing

Embodiment Construction

[0014] Now, the present invention will be described in further detail in conjunction with preferred embodiments.

[0015] The present invention is a kind of manufacturing process of nuclear industry sealing head, comprises the following steps:

[0016] 1) Cut the qualified steel plate, and chamfer the end face of the disc during cutting;

[0017] 2) Welding with welding test plate;

[0018] 3) After welding is completed, perform post-weld heat treatment, and the temperature of post-weld heat treatment is 625°C;

[0019] 4) Drum pressing the disc, and after the drum pressing, carry out hot spinning with the base metal test plate and welding test plate in the furnace to make the head;

[0020] 5) Perform normalizing heat treatment on the head after hot spinning, the temperature of normalizing heat treatment is 900°C, and bring the base metal test plate and welding test plate with the furnace;

[0021] 6) After the head is formed, sandblast the inner and outer surfaces of the ...

Abstract

The invention relates to a process for manufacturing an end socket for a nuclear industry. The process comprises the following steps of: material purchasing, acceptance of materials, cutting, welding, heat treatment, swell pressing, hot spinning and heat treatment. The invention discloses the process for manufacturing the end socket for the nuclear power, which is autonomously developed in China, and the process for manufacturing the end socket for the nuclear power is controlled strictly according to the nuclear power specification; the end socket manufactured in a hot stamping or hot spinning mode completely meets the nuclear specifications; and compared with the like products in foreign countries, the end socket reduces the total manufacturing cost of a nuclear power station under the condition of the same quality.

Description

technical field [0001] The invention relates to a head manufacturing process, in particular to a head manufacturing process for the nuclear industry. Background technique [0002] China will vigorously develop nuclear power plants, and the demand for heads in nuclear power plants is very extensive. Since the operation of nuclear power plants involves the safety of people and property, the safety control is very strict, so the main components of nuclear power plants generally rely on imports. Among them, the requirements for the head are also extremely strict, and the processing of the head must be thermal processing. Usually the head product specification is EHA4200*44SA516Gr70. [0003] With the rapid development of China's domestic nuclear power plants, the demand for nuclear power heads is also increasing. If such heads are imported from abroad, it will inevitably affect the development speed of nuclear power plants. It will also be restricted by the foreign environment...
