Bogie hearth furnaces offer many advantages in production. Outside the furnace, the bogie can be accessed from three sides and can be easily loaded using a crane or forklift truck. If several bogies are used, one can be charged while the other is positioned in the furnace. By adding additional equipment, e.g. multi-zone control for optimization of temperature uniformity or controlled cooling systems to shorten cycle times, these furnaces can be optimally tailored to the respective production process. The upscale into fully automatic systems is also possible, using motor-driven bogies and a rail system for bogie exchange.

With their sturdy construction and very good temperature uniformity, these models are ideal for cooling and relieving stress in glass, for burning in coatings and for tempering quartz glass.

  • Tmax 1280 °C, 1340 °C or 1400 °C
  • Dual shell ventilated housing made of textured stainless steel sheets for low surface temperature and high stability
  • Swing door hinged on the right side
  • Heating from five sides (four sides and bogie) provides for a very good temperature uniformity
  • Heating elements on support tubes provide for free heat radiation and long service life
  • Bottom heating protected by SiC tiles with an even stacking base
  • Self-supporting and long-life ceiling construction with bricks laid in arched construction
  • Exclusive use of insulation materials without categorization according to EC Regulation No 1272/2008 (CLP). This explicitly means that alumino silicate wool, also known as “refractory ceramic fiber” (RCF), which is classified and possibly carcinogenic, is not used.
  • Freely moveable bogie with rubber wheels up to model W 3300. Larger models have flange wheels and run on rails. 
  • Adjustable air inlet damper
  • Motorized exhaust air flap on the furnace roof
  • Inlets in the front corners of the bogie 2 x D = 40 mm for the customer’s thermocouples
  • Over-temperature limiter with adjustable cutout temperature as temperature limiter to protect the furnace and load
  • Defined application within the constraints of the operating instructions
  • Controller with touch operation P570 (50 programs with each 40 segments)
  • NTLog Basic for Nabertherm controller: recording of process data with USB‑flash drive
  • Freeware NTEdit for convenient program input via Excel™ for Windows™ on the PC
  • Freeware NTGraph for evaluation and documention of firings using Excel™ for Windows™ on the PC
  • MyNabertherm App for online monitoring of the firing on mobile devices for free download 

Дополнительное оборудование

  • Multi-zone control to optimize the temperature uniformity
  • Cooling system to speed up furnace cooling with a fan and specified temperature gradients or a fixed volume of fresh air
  • 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
  • Different possibilities for an extension to a bogie hearth furnace system:
    • More bogies
    • Bogie transfer system with parking rails to exchange bogies running on rails or to connect multiples furnaces
    • Fully automatic control of the bogie exchange
  • Electro-hydraulic lift door
  • Alternating use of two bogies with lift doors in front of and behind the furnace
  • Facilities to hold charging trolley/furniture
  • Fiber insulation for short process times
  • Safety concepts for debinding
  • Thermal or catalytic post combustion systems
  • Process control and documentation via VCD software package for monitoring, documentation and control
