るつぼせいれんこう（ひてつきんぞくせいれん）
Industry & Occupation
Classification
Summary
Manufacturing operation role that melts nonferrous metal ores or metal scraps in a crucible furnace to recover and refine metals.
Description
Crucible smelters use crucible furnaces to melt nonferrous metal ores or scraps at approximately 1000–1500°C, adjust chemical compositions, recover, and refine metals. Responsibilities include raw material charging, temperature control, chemical reduction and oxidation reaction control, slag removal, and molten metal casting. Work also involves refractory repairs, furnace gas management, and safety device inspections. Requires physical stamina and attention to detail to endure high-temperature environments and heavy labor.
Future Outlook
Demand for nonferrous metal smelting is expected to remain stable due to resource recycling and stricter environmental regulations. With the introduction of IoT and automation technologies, advanced control skills and equipment maintenance capabilities will be increasingly required.
