Bogie Hearth Furnace for heat treatment

Enabling multiple heat treatment processes to meet diverse needs

Bogie hearth furnaces can complete various heat treatment processes such as annealing, normalizing, quenching, tempering, and carburizing by precisely controlling parameters like temperature and atmosphere. They are suitable for batch processing of metal workpieces (e.g., steel products, castings, forgings) and can meet processing requirements of different materials and performance specifications.

Excellent capability in handling large-sized/batch workpieces

With a relatively large furnace space and a movable bogie, they facilitate the loading and unloading of large, heavy workpieces or batches of small and medium-sized workpieces. This allows efficient utilization of the furnace interior space and improves the efficiency of heat treatment production.

High temperature uniformity ensuring stable workpiece quality

The furnace is usually equipped with multiple groups of heating elements arranged symmetrically, combined with a forced circulation fan (in some models). This enables uniform temperature distribution inside the furnace chamber (with a temperature difference generally controllable within ±5℃), ensuring consistent heating of all parts of the workpiece and reducing issues like deformation and uneven performance caused by temperature differences.

Convenient operation with customizable automation levels

They feature manually or automatically controlled mechanisms for bogie entry/exit and furnace door opening/closing. The temperature control system can accurately set heating, holding, and cooling curves. Some high-end models can also integrate a PLC control system to achieve fully automatic production, reducing manual operation intensity while enhancing process repeatability and reliability.
