Embodiment 1

[0027] A kind of processing technology of first wall U-shaped flow-containing cooling pipe group test piece, this technology comprises the following steps:

[0028] Step 1: select the spherical powder based on the CLF-1 chemical composition formula of the Southwest Institute of Physics of the Nuclear Industry, and use the laser stereoforming process to process it into such figure 1 The unslotted U-shaped frame sub-assembly 1 is shown. The specific way is to use the laser stereoforming manufacturing equipment model LSF-III, first generate a three-dimensional CAD model of the U-shaped frame component 1 in the computer, and then "slice" the model in layers with a certain thickness of 0.5mm, that is, The three-dimensional data information of the U-shaped frame component 1 is converted into a series of two-dimensional contour information, and then the laser cladding method is used to accumulate materials layer by layer according to the contour trajectory, and finally forms such as ...

Embodiment 2

[0034] Manufacture the first wall U-shaped flow-containing cooling pipe group according to the same processing technology as in Example 1, the difference is that:

[0035] (1) The spherical powder of the low-activation ferrite / martensitic steel used in step one is based on the CLAM chemical composition formula of the Institute of Plasma, Chinese Academy of Sciences;

[0036] (2) In step 3, use a VacBond type high-frequency induction heating vacuum diffusion welding machine to butt two U-shaped frame components 1 with U-shaped grooves 2 into a U-shaped cooling pipe 3 .

Abstract

The invention discloses a technology for processing a test blanket module (TBM) first wall U-shaped flow-containing cooling pipeline set. The technology comprises the following steps of:1, processing U-shaped frame components by using reduced activation ferritic/martensitic spherical powder; 2, processing a U-shaped groove on each U-shaped frame component in a U-shaped frame direction; 3, performing butt point processing on two U-shaped frame components on which the U-shaped grooves are processed to form a U-shaped cooling pipeline; and 4, vertically and sequentially stacking the U-shaped cooling pipelines, and performing butt joint on the U-shaped cooling pipelines to realize the integration of the first wall U-shaped cooling pipeline set. The technology can greatly improve material utilization rate, quality safety performance, and avoid the problems of high price, large difficulty in a technology and the like in a hot isostatic pressing technology.

Description

technical field [0001] The invention belongs to the field of mechanical processing, and in particular relates to a processing technology of a U-shaped flow-containing cooling pipe group on the first wall of a TBM. Background technique [0002] The ITER device is the first fusion reactor-level experimental device. It was initiated by the heads of the former Soviet Union and the United States in 1985. At present, seven members are involved. The device will be completed, put into operation and obtain initial plasma in 2016, 500 M Watt fusion power. It is not only used to integrate and verify the feasibility of fusion energy, but also to partially verify the engineering technical issues of fusion reactors. ITER provides a real fusion neutron environment, and the fusion neutron production rate reaches 1.8×10 20 n / s, this is a very important volume neutron source that can be used to verify key technologies such as tritium self-sustainment and energy conversion of fusion demonstr...
