Nabertherm High-Temperature Furnace with SiC Rod Heating in Furnaces, Ovens

Nabertherm High-Temperature Furnace with SiC Rod Heating HTC 16/16 - HTC 450/16
The high-temperature furnaces are heated by vertically hung SiC rods, which makes them especially suitable for sintering processes up to a maximum operating temperature of 1550 °C. For some processes, e.g. for sintering zirconium oxide, the absence of interactivity between the charge and the SiC rods, these models are more suitable than the alternatives heated with molybdenum-disilicide elements. The basic construction of these furnaces make them comparable with the already familiar models in the HT product line and they can be upgraded with the same additional equipment.

• Tmax 1550 °C
• Dual shell housing with fan cooling for low shell temperatures
• Heating from both sides via vertically mounted SiC rods
• High-quality fiber insulation backed by special insulation
• Side insulation constructed with tongue and groove blocks provides for low heat loss to the outside
• Long-life roof insulation with special suspension
• Chain-guided parallel swivel door for defined opening and closing of the door without destroying the insulation
• Two-door design (front/back) for high-temperature furnaces > HTC 276/..
• Labyrinth sealing ensures the least possible temperature loss in the door area
• Reinforced floor as protection for bottom insulation
• Exhaust air opening in the furnace roof
• Heating elements switched via SCR?s
• Over-temperature limiter with adjustable cutout temperature for thermal protection class 2 in accordance with EN 60519-2 as temperature limiter to protect the furnace and load
• NTLog Basic for Nabertherm controller: recording of process data with USB-flash drive

Additional equipment

• Uncontrolled or controlled cooling system with frequency-controlled cooling fan and motor-driven exhaust air flap
• Furnace in DB design featuring fresh air preheating, exhaust gas ventilation and an extensive safety package for debinding and sintering in one process, i. e. without transfering the material from the debinding furnace to the sintering furnace
• Stainless steel exhaust gas top hats
• Special heating elements for zirconia sintering provide for longer service life with respect to chemical interaction between charge and heating elements
• Protective gas connection to purge with non-flammable protective or reaction gases
• Manual or automatic gas supply system
• Inner process box to improve the gas tightness and to protect the furnace chamber against contamination
• Lift door
• Motorized exhaust air flap, switchable via the program
• Thermal or catalytic exhaust cleaning systems
• Process control and documentation via VCD software package or Nabertherm Control Center (NCC) for monitoring, documentation and control
