AI Technical Summary

Technical Problem

The existing smelting process for Li17Pb83 alloy is complex and costly, and impurities and component segregation are easily introduced during the smelting process, affecting the alloy properties and the complexity of the subsequent tritium extraction process.

Method used

Using a vacuum induction furnace and inert gas protection, 3-10mm granular lithium metal is combined with lead metal. The feeding rate is controlled at 5-15g/min, the melting temperature is 285-335℃, and alloying is completed within 10-30 minutes. The mixture is then directly cast into shape, avoiding the steps of high-temperature settling and melt filtration.

Benefits of technology

It achieves precise control of alloy composition, reduces impurity content, lowers production costs, improves composition consistency, avoids composition segregation, simplifies the process, and reduces energy consumption.

Abstract

The application relates to the technical field of alloy materials, in particular to a preparation method of a lithium-lead alloy Li 17 Pb 83 for nuclear industry. The preparation method comprises the following steps: preparing metal lead and granular metal lithium, the average particle size of the granular metal lithium is 3-10 mm; the metal lead is placed in an oxide crucible of a vacuum induction furnace, and the granular metal lithium is placed in a secondary feeding hopper; after vacuum treatment of the vacuum induction furnace, inert gas is filled; the metal lead is heated and melted, then the granular metal lithium is added into the lead melt at a rate of 5-15 g / min; and then smelting is carried out at 285-335 DEG C for 10-30 min, and then casting is formed. Through the above process, the lithium-lead alloy Li 17 Pb 83 prepared by the application has uniform components, and secondary smelting is not needed, and the alloy ingot has good melting point and component consistency.
