Industry & Occupation
Classification
Summary
Steelmaking furnace builders lay and repair refractory bricks and mortar inside steel mill furnaces, maintaining the heat insulation and durability of steel melting furnaces as specialized technicians.
Description
Steelmaking furnace builders are specialists who construct, repair, and inspect furnace interiors using refractory bricks and refractory mortar in the high-temperature furnaces of steel plants. Based on drawings, they stack refractory materials to precise dimensions, utilizing construction skills such as crane and slinging operations or scaffolding assembly, while carrying out repairs for cracks or damaged areas, and new construction or renovation work. Safety management in high-temperature and heavy labor environments, as well as team coordination, are essential.
Future Outlook
Steady demand is expected due to equipment renewal in the domestic steelmaking industry and innovations in refractory material technology. Acquiring furnace interior monitoring technology using IoT and automation will be key in the future.
