Classification

Summary

Architectural technicians who construct and repair refractory linings on the inner walls of high-temperature furnaces and kilns using refractory bricks, refractory mortar, and other refractory materials.

Description

Furnace builders are craftsmen and technicians who construct and repair refractories inside high-temperature facilities such as steel mills, chemical plants, and ceramic kilns. They stack refractory bricks, apply refractory mortar and castables, and finish the joints based on specification drawings. Since work is performed in high-temperature and dusty environments, dust control, temperature management, and safety management are important. On-site, they use tools such as hammers, trowels, and grinders, install temporary scaffolding, mix mortar, and employ dry and wet lining techniques to perform construction that accommodates the thermal expansion characteristics of the furnace.

Future Outlook

With the renewal and energy-saving upgrades of steel mills and chemical plants, the performance of furnace linings is advancing, so demand for personnel with expertise in refractory materials and construction techniques is expected to remain stable.
