Bogie Hearth Furnaces with Wire Heating up to 1400 °C FURNA PECKA ZA VISOKA TEMPERATURA ZA STAKLO

W 1000 - W 10000/14, W 1000/DB - W 10000/14DB

When cooling, decorating, glazing or sintering special glass during production, bogie hearth furnaces offer numerous advantages. Due to their very good temperature uniformity, these models are perfectly suited for burning in a separation layer of silicon nitride in crucibles for the solar industry. The bogie can be charged outside the furnace. Several shuttles can be used, so that one shuttle can be charged while the other shuttle is in the furnace.

• Tmax 1280  °C, 1340  °C or 1400  °C
• Dual shell housing with rear ventilation, provides for low shell temperatures
• Swing door hinged on the right side
• Heating from five sides (four sides and bogie) provides for an optimum 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 exhaust air flap on the furnace roof
• Over-temperature limiter 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
• Uncontrolled or controlled cooling system with frequency-controlled cooling fan and motor-driven 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
• Thermal or catalytic exhaust cleaning systems
• Process documentation and control with Controltherm MV software package, NTLog and NTGraph for the basic furnace or Nabertherm Control Center (NCC) for monitoring, documentation and control
