High-temperature eutectic pre-fused eutectic pouring crucible

Abstract

The invention relates to a high-temperature eutectic pre-fused eutectic pouring crucible, and belongs to the technical field of high-temperature eutectics. The crucible is cylindrical in appearance, and comprises a pre-fused eutectic crucible cover and a pre-fused eutectic crucible main body, wherein the pre-fused eutectic crucible main body is provided with a male thread; the pre-fused eutectic crucible cover is provided with a female thread which is matched with the male thread; the pre-fused eutectic crucible main body is in a threaded connection with the pre-fused eutectic crucible cover. After an eutectic is formed in a pre-fused eutectic crucible, the eutectic is connected to the eutectic crucible in an inverted way, changes into a molten state after being heated, and flows into the eutectic crucible under the action of gravity in order to realize pouring of the eutectic crucible. By adopting the high-temperature eutectic pre-fused eutectic pouring crucible, the breaking risk of the pre-fused eutectic crucible is lowered, the eutectic is prevented from adhering to a joint between the pre-fused eutectic crucible and the eutectic crucible, the pre-fused eutectic crucible can be reused, the problem that an existing pre-fused eutectic container can only be used once is solved, and the pouring cost is lowered.

Description

technical field [0001] The invention relates to a high-temperature eutectic point pre-eutectic pouring crucible, which belongs to the technical field of high-temperature eutectic point. Background technique [0002] With the development of high-temperature eutectic point technology, it has become a reality to use metal-carbon high-temperature eutectic point instead of pure metal fixed point above the Ag fixed point. This is of great significance for reducing the uncertainty of the current ITS-90 temperature scale above the Ag fixed point. At present, the Radiation Thermometry Working Group of the International Temperature Advisory Committee has made it clear that it will add Co-C, Pt-c and Re-C eutectic points to the new temperature scale, which has promoted research in the field of eutectic points by research institutions around the world. [0003] At present, the commonly used high-temperature eutectic point infusion methods are mainly direct eutectic infusion method and ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to solve the pre-eutectic pouring method that is easy to break due to the thinner wall thickness, the pre-eutectic container cannot be reused, and the eutectic bonding between the pre-eutectic container and the eutectic point crucible is easy to occur, resulting in failure To remove the pre-eutectic container and other problems, a high-temperature eutectic point pre-eutectic perfusion crucible is designed
