Problems solved by technology
[0004] However, according to the current process, the high-temperature metal obtained by molten salt electrolytic refining still needs to be thoroughly cooled for more than 12 hours before it can be taken out from the vacuum (or inert gas protection) environment. High-purity metals in powder, granular or dendritic form are scraped off and collected, which causes high-purity metal products to be easily oxidized and contaminated, and the labor intensity is high, the production continuity is poor, and the production efficiency is low
