Lift-Top or Lift-Bottom Furnaces with Wire Heating up to 1400 °C FURNA PECKA ZA VISOKA TEMPERATURA



H 125/LB or LT - H 3000/LB or LT

In production lift-top and lift-bottom furnaces have the advantage in comparison with chamber furnaces that even complex charge loads can be clearly arranged. The basic furnace is equipped with a table fixed in place under the hood. The system can be expanded to include one or more changeable tables, either manually or motor driven. Depending on process conditions, a lift-top- or lift-bottom version is advisable. Further additional equipment like a multi-zone control to optimize the temperature uniformity or controlled cooling systems for shorter processes provide for customized solution with respect to the process requirements. A combi furnace version with debinding package I or II for debinding and sintering in a single process is also available. The furnaces are moreover perfectly suited for special applications like sintering fuel cells, in which auxiliary fittings must be introduced in the furnace from below or above.

  • Tmax 1280  °C
  • Dual shell housing with rear ventilation for low shell temperatures
  • Electrohydraulically driven hood with fixed table
  • Five-sided heating from all four sides and from the table provides for a good temperature uniformity
  • Heating elements mounted on support tubes provide for free radiation and long service life of the heating wire
  • Bottom heating protected by SiC tiles which provide for a level stacking surface
  • Multi-layer insulation consisting of lightweight refractory bricks backed by special insulation
  • Long-life ceiling design with fiber insulation
  • 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

  • Tmax to 1400  °C
  • Lift-bottom furnace version with driven table and fixed hood
  • Uncontrolled or controlled cooling system with frequency-controlled cooling fan and motor-driven exhaust air flap
  • Protective gas connection for purging the furnace with non-flammable protective or reaction gases
  • Manual or automatic gas supply systems
  • 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
  • Additional tables, table changing system, also motor-driven
  • Motor-driven exhaust air flap, switchable via the program
  • Debinding package I with passive safety package and monitoring of the underpressure in the furnace chamber, exhaust gas fan, fresh air fan, preset underpressure in the furnace chamber, controlled by Nabertherm controller P 300
  • Debinding package II with passive safety concept
  • Exhaust air and exhaust gas piping
  • Thermal or catalytic exhaust cleaning systems
  • Heat recovery 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
