Glass /High-Temperature Furnaces

The high-temperature furnaces HT 04/16 - HT 450/18 have proven reliability over many years in laboratory and production. Whether for quartz glass or glass ceramics, for sintering CIM components or for other processes up to a maximum temperature of 1800 °C, these furnaces afford the optimal solution for the sintering process.

High-temperature furnaces can either be insulated with fiber material or lightweight refractory bricks. Furnaces with fiber insulation achieve significantly shorter heating up times because of the low thermal mass. An insulation made of lightweight refractory bricks (see HFL models on page 32), on the other hand, has the advantage of better chemical stability.

These furnaces can also be tailored to specific processes by means of a wide range of additional equipment. The addition of a debinding package, for example, allows the use of these models as combi furnace for debinding and sintering in one process. Thermal or catalytic exhaust cleaning equipment rounds-off the system.

• Tmax 1600  °C, 1750  °C or 1800  °C
• Recommended working temperature 1750 °C (for models HT ../18), increased wear and tear must be expected in case of working at higher temperatures
• Dual shell housing with fan cooling for low shell temperatures
• Heating from both sides via molybdenum disilicide heating elements
• 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
• Two-door design (front/back) for high-temperature furnaces > HT 276/..
• Labyrinth sealing ensures the least possible temperature loss in the door area
• Reinforced floor as protection for fiber insulation as standard from models HT 16/16 upwards
• Exhaust air opening in the furnace roof
• Heating elements switched via thyristors
• 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
• Defined application within the constraints of the operating instructions
• 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 transferring the material from the debinding furnace to the sintering furnace
• Stainless steel exhaust gas hoods
• Commissioning of the furnace with test firing and temperature uniformity measurement (also with load) for the purpose of process optimization
• Temperature measurement with thermocouples, types B and type S with automatic pull-out device for precise control results in the low-temperature range
• Protection grid in front of the heating elements to prevent mechanical damages
• Special heating elements for zirconia sintering provide for longer service life with respect to chemical interaction between charge and heating elements
• Protective gas connection for purging the furnace with non-flammable protective or reaction gases
• The manual or automatic gas supply system
• Inner process box to improve the gas tightness and to protect the furnace chamber against contamination
• Lift door
• Bottom insulation made of durable lightweight refractory bricks for heavy charge weights
• Motorized exhaust air flap, switchable via the program
• Exhaust air and exhaust gas piping
• Thermal or catalytic exhaust cleaning systems
• FID measurement for process optimization
• Process control and documentation via VCD software package or Nabertherm Control Center (NCC) for monitoring, documentation, and control
