Industry & Occupation
Classification
Summary
Worker who uses a vacuum furnace to melt and refine oxygen-free copper to produce high-purity copper.
Description
The Vacuum Melting Worker (Oxygen-Free Copper Smelting) is a profession that uses vacuum furnaces or electric furnaces to melt copper raw materials at high temperatures, remove oxygen and impurities, and manufacture oxygen-free copper. Responsibilities broadly include furnace temperature and vacuum level management, quality confirmation through metal filtration and chemical analysis, preparation for casting after melting, equipment maintenance and inspection, and safety management. Since the work is centered in high-temperature and vacuum environments, wearing heat-resistant equipment and strictly adhering to procedures are required.
Future Outlook
With the spread of semiconductors and electric vehicles, demand for high-purity copper is increasing, and demand for specialized technicians is expected to remain stable. Equipment operation will also become more advanced due to automation and IoT.
