Industry & Occupation
Classification
Summary
Furnace operators (metal heat treatment) use furnaces to control heating and cooling, performing heat treatments such as quenching, tempering, and annealing to improve the strength and performance of metal parts.
Description
Furnace operators (metal heat treatment) load metal materials such as steel, iron, and aluminum into furnaces and perform heat treatment while managing temperature, time, and atmosphere (gas/vacuum). They strictly adhere to temperature profiles for each process such as quenching, tempering, and annealing, and appropriately select and operate cooling methods (air cooling, water cooling, oil cooling) afterward. After processing, they conduct quality checks such as hardness testing, visual inspection, and dimensional measurement to ensure products meet specifications. Maintenance and inspection of furnaces and auxiliary equipment, management of safety devices, and creation of work records are also important tasks.
Future Outlook
While automation and IoT adoption in manufacturing are advancing, skilled furnace operators are essential for operating complex heat treatment processes. Demand is expected to remain stable in the future.
