Method for forming reactor internal integral compression structure

Abstract

The invention belongs to the field of reactor structure design, and particularly relates to a method for forming a reactor internal integral compression structure. The invention aims to provide a method for forming a reactor internal integral compression structure in order to overcome the defects in the prior art. The production of section bars and matched welding materials is canceled, so that the production period is shortened; all full penetration weld joints are canceled, so that the welding deformation of the structure is avoided, and the forming quality is improved; the procedure of machining a large number of flowing water through holes is omitted, and machining deformation of the structure is avoided; an integrally-formed pressing structure is adopted, the structural continuity isgood, and the mechanical property is better; the integrally-formed pressing structure is uniform in structural material performance, and particularly, the material performance in the thickness direction of the structure is not different; the manufacturing process is greatly simplified, and the manufacturing period is greatly shortened.

Description

technical field [0001] The invention belongs to the field of reactor structure design, and in particular relates to a method for forming an integrated compression structure of reactor internal components. Background technique [0002] The compression structure of the reactor internals is a key part of the reactor structure. At present, the commonly used manufacturing process is: first, the plate is rolled and welded to form the skirt, and the upper support flange and the lower support plate processed by forgings are fully welded to the skirt. The welded connection is integrated, and multi-layer flow holes distributed uniformly in the radial direction are processed. The required raw materials include plates, forgings and supporting welding materials. The time period of this manufacturing process is longer, the welding process is more complicated, and the amount of welding deformation is larger. When processing a large number of through holes, the processing cycle is longer an...
