Nabertherm High-Temperature Furnaces with SiC Rod Heating HTC 16/16 - HTC 450/16
These high-temperature furnaces are especially suitable for sintering processes up to a maximum working temperature of 1550 °C due to the heating by vertically suspended SiC rods. For certain processes, e.g. sintering of zirconium oxide, SiC rods may be more suitable than heating elements made of molybdenum disilicide due to the lack of interactivity with the charge. In terms of basic design, the furnaces are comparable to the models of the HT series and can be upgraded with the same additional equipment.
- Tmax 1550 °C
- Double-walled housing construction with fan cooling, thus low outer wall temperature
- Heating from both sides via vertically suspended SiC rods
- High-quality fibre insulation with special back insulation
- Side insulation, constructed of tongue and groove blocks, ensures low heat loss to the outside
- Durable ceiling insulation with special suspension
- Parallel swing door with chain guide for defined opening and closing of the door without destroying the insulation
- Double-door design (front/rear) for high-temperature ovens > HTC 276/..
- Labyrinth seal ensures the lowest possible temperature losses in the door area
- Bottom reinforcement with level stacking support to protect the fibre insulation and to accommodate heavy superstructures
- Exhaust air opening in the furnace ceiling
- Heating elements controlled by thyristors
- Over-temperature limit controller with adjustable cut-off temperature for thermal protection class 2 acc. to EN 60519-2 as over-temperature protection for the oven and the fabric
- NTLog Basic for Nabertherm controller: recording of process data with USB stick
Additional equipment
- Unregulated or regulated cooling system with frequency-controlled cooling fan and motorised exhaust air flap
- Furnace in DB version with fresh air preheating, exhaust fan and comprehensive safety package for debinding and sintering in one process, i.e. without transferring the product from the debinding furnace to the sintering furnace
- Exhaust bonnets made of stainless steel
- Special heating elements for sintering zirconium oxide with longer service life with regard to chemical interactions between product and heating elements
- Protective gas connection for purging the furnace with non-flammable protective or reaction gases
- Manual or automatic gas supply system
- Process insert box to improve gas tightness and protect the oven chamber against contamination
- Lift door
- Motor-driven exhaust air flap, switchable via the programme
- Thermal or catalytic exhaust gas cleaning systems
- Process control and documentation via VCD software package or Nabertherm Control Center NCC for monitoring, documentation and control
