Bogie hearth furnaces offer a whole series of advantages in firing, sintering and tempering in production. The bogie can be loaded outside the furnace. If multiple bogies are used, one bogie can be loaded while the other is in use in the furnace. Useful accessories like multi-zone control to optimize the temperature uniformity, controlled cooling systems to shorten process times to the fully automatic system with motorized bogies and bogie exchange provide for the perfect adaptation of these furnaces to production process. A combi furnace version with debinding package for debinding and sintering in a single process is also possible.

• Tmax 1280 °C, 1340 °C or 1400 °C
• Double-walled housing with rear ventilation, provides low shell temperatures
• Swing door hinged on the right side
• Heating from five sides (four sides and bogie) provides for a good temperature uniformity
• Bogie heating receives power via blade contacts when driven in
• Heating elements mounted on support tubes provide for free radiation and long service life
• Bottom heating protected by SiC tiles on the bogie providing level stacking surface
• Multi-layer insulation consisting of lightweight refractory bricks backed by microporus silica insulation
• Self-supporting and long-life ceiling construction with bricks laid in arched construction, for models up to 1340 °C or as fiber insulation
• Roof made of high-quality fiber material for models with Tmax 1400 °C
• Bogies freely movable with rubber tires
• Adjustable air inlet damper
• Manual vapor vent on the furnace roof
• Over-temperature limit controller with manual reset for thermal protection class 2 in accordance with EN 60519-2 as temperature limiter to protect the furnace and load

Additional equipment

• Customized dimensions
• Fiber insulation for short heating time requirements
• Bogies with flanged wheels running on rails for easy and precise movement of high loads or complex kiln furniture
• Electric chain-driven bogie in combination with rail operation for smooth movement of heavy loads
• Bogie running on steel wheels with gear rack drive, no rails in front of the furnace necessary
• Different possibilities for an extension to a bogie hearth furnace system:
  • Additional bogies
  • Bogie transfer system with parking rails to exchange bogies running on rails or to connect multiples furnaces
  • Motor-driven bogies and cross-traversal system
  • Fully automatic control of the bogie exchange
• Electro-hydraulic lift door
• Customized kiln furniture
• Motor-driven exhaust air flap, switchable via the program
• Controlled cooling system with frequency-controlled cooling fan and motorized exhaust air flap
• Multi-zone control adapted to the particular furnace provides model for optimal the temperature uniformity
• Commissioning of the furnace with test firing and temperature uniformity measurement (also with load) for the purpose of process optimization
• Debinding packages with passive safety concept
• Thermal or catalytic exhaust cleaning systems
• Process documentation and control with Controltherm MV software package for the basic furnace or Nabertherm Control Center (NCC) for monitoring, documentation and control for use of Debinding Package II
