Electric furnace worker (non-ferrous metal smelting)
でんきろこう（ひてつきんぞくせいれん）
Industry & Occupation
Classification
Summary
Operators who use electric furnaces to melt and refine non-ferrous metals such as aluminum and copper, adjust them to the specified quality, and supply them to the casting process.
Description
Electric furnace workers (non-ferrous metal smelting) use electric arc or induction heating furnaces to melt non-ferrous metals such as aluminum, copper, and zinc. They adjust temperature, analyze the chemical composition of the molten metal, remove slag, adjust alloys, and supply molten metal of the specified quality to the casting process. During operations, they also handle electrode replacement, sampling and analysis of furnace interior samples, inspection and maintenance of the furnace body and peripheral equipment, safety management, and measures against exhaust gas, noise, and dust. The work involves standing in high-temperature environments and handling heavy materials, requiring skills and qualifications such as crane operation and high-pressure gas handling.
Future Outlook
With the introduction of automation and IoT, basic operations will increasingly become remote and automated, while the demand for skilled personnel in equipment maintenance, quality control, and data analysis is expected to increase.
