Embodiment 1

[0030] like figure 1 As shown, a test device for lead-bismuth alloy melt erosion corrosion test includes a test kettle 3 and a sample holder 5 arranged in the test kettle 3, and also includes a rotating shaft 8, and the sample holder 5 is rotated by rotating The shaft 8 is rotatably installed in the test kettle 3 .

[0031] In the prior art, in order to realize the research on erosion corrosion of materials in high-temperature lead-bismuth melt, it is necessary to use a corrosion test device, and the corrosion test device includes a lead-bismuth alloy melt circulation loop. Strong corrosiveness. In the prior art, the circulating pump vanes that can meet the needs of melt circulation are very easy to be severely corroded by the lead-bismuth alloy melt. Lower overall reliability, higher maintenance frequency and higher operating costs.

[0032] In this solution, the sample holder 5 provides a sample installation station for fixing the sample to be tested. By setting the sample...

Embodiment 2

[0036] like figure 1 As shown, this embodiment is further limited on the basis of Embodiment 1:

[0037] As a more complete technical solution that can directly provide a heat source for obtaining or maintaining the lead-bismuth alloy melt state, it is set as follows: a heating furnace 1 is further included, and the test kettle 3 is installed in the heating furnace 1, and the heating furnace 1 is installed in the heating furnace 1. Furnace 1 was used to heat test kettle 3 .

[0038] As a technical solution that the test kettle 3 itself has high strength and the surface layer is corrosion-resistant, it is set as follows: the test kettle 3 is a cylindrical structure made of stainless steel, and also includes an anti-corrosion lining 4 arranged inside the test kettle 3 .

[0039] As one kind of the anti-corrosion lining 4, a specific lead-bismuth alloy melt corrosion resistance is good and easy to obtain. The anti-corrosion lining 4 is a ceramic crucible.

[0040] Since the sam...

Abstract

The invention discloses a test device for erosion corrosion test of lead-bismuth alloy melt, which includes a test kettle and a sample holder arranged in the test kettle, and also includes a rotating shaft, and the sample holder is rotatably installed through the rotating shaft in the test kettle. Using the test device provided by this scheme can simplify the erosion and corrosion test equipment, improve the reliability of the erosion and corrosion equipment, and reduce equipment maintenance and operation costs.

Description

technical field [0001] The invention relates to the technical field of lead-bismuth fast reactor material corrosion test, in particular to a test device used for lead-bismuth alloy melt erosion corrosion test. Background technique [0002] The lead-bismuth fast reactor is the fourth generation reactor. Corrosion of materials in high-temperature lead-bismuth melts is a major challenge for lead-bismuth fast reactors. Erosion corrosion studies of materials in high temperature lead and bismuth melts are usually carried out in corrosion test devices with loops. This kind of test device mainly includes two parts: test kettle and lead and bismuth circulation loop. Due to the high temperature lead and bismuth melt, the corrosion of the test kettle and the circuit materials is relatively large, and there may be serious corrosion of the circulating pump blades and the deposition of corrosion products in the circuit, resulting in low reliability and high maintenance and operation cos...
