Sintering Worker (Metal Smelting)
だんこうこう（きんぞくせいれん）
Industry & Occupation
Classification
Summary
Manufacturing technician who operates blast furnaces or electric furnaces to melt and refine ore into ingots or molten metal.
Description
Sintering workers (metal smelting) operate melting furnaces such as blast furnaces and electric furnaces to melt and refine raw materials for steel and non-ferrous metals, producing ingots and molten metal for casting. They blend raw materials such as ore, coke, and limestone in appropriate ratios, and monitor and analyze furnace temperature and chemical composition while proceeding with melting. They perform slag removal, molten metal tapping, pouring into molds, etc., and are also responsible for quality control, equipment maintenance inspections, and safety and health management. The work environment often involves high temperatures, dust, and noise, requiring strict procedures and coordinated team operations.
Future Outlook
While Japan's steel and metal smelting industry is supported by stable demand, labor-saving automation and decarbonization technologies are accelerating, increasing the demand for skilled workers who can handle environmental measures and digital technologies.
