High-Temperature Furnaces with Molybdenum Disilicide Heating Elements with Fiber Insulation up to 1800 °C
The addition of a debinding package, for example, allows the use of these models as combi furnaces for debinding and sintering in one process.
Function and equipment
Thanks to the sturdy design, the high-temperature furnaces fulfill the demands of everyday use in laboratories and production. The compact standard models are particularly suitable for the production of technical ceramics such as bio ceramics or the sintering of CIM components where high working temperatures are needed and high-quality standards are required. The very good temperature uniformity and useful options set high-quality benchmarks and are the optimum solution for many applications. The furnaces can be extended with extra features from our extensive range to suit specific processes.
- Tmax 1600 °C, 1750 °C, or 1800 °C
- Recommended maximum working temperature approx. 50 °C below Tmax of the furnace. Higher working temperatures will increase wear and tear.
- Dual shell ventilated housing made of textured stainless steel sheets for low surface temperature and high stability
- Heating from both sides via molybdenum disilicide heating elements
- High-quality fiber insulation backed by special insulation
- Exclusive use of insulation materials without categorization according to EC Regulation No 1272/2008 (CLP). This explicitly means that alumino silicate wool, also known as “refractory ceramic fiber” (RCF), which is classified and possibly carcinogenic, is not used.
- Long-life roof insulation with special suspension
- Temperature uniformity at 1450 °C up to +/− 6 °C according to DIN 17052-1
- Chain-guided parallel swivel door for precise opening and closing of the door
- Two-door design (front/back) for high-temperature furnaces from HT 276/..
- Labyrinth sealing ensures the least possible temperature loss in the door area
- Reinforced floor as protection for bottom insulation as standard from models HT 16/16 upwards (distributed load 5 kg/dm2)
- Vapor vent in the furnace roof with motorized exhaust air flap, controlled via the extra function of the controller
- Stainless steel exhaust hood as interface to customer’s exhaust system
- Over-temperature limiter with adjustable cutout temperature as temperature limiter to protect the furnace and load
- Defined application within the constraints of the operating instructions
- Controller with touch operation P570 (50 programs with each 40 segments)
Additional equipment
- Cooling system to cool the furnace with a defined temperature gradient or with a preset fresh air volume. Both operating modes can be switched on and off for different segments by means of the extra function of the controller.
- Thermocouple inlet with screw cap
- Thermocouple for the heating control with calibration certificate
- Protective gas connection to purge with non-flammable process gases (not completely gas-tight)
- Automatic gas supply system with solenoid valve and rotameter, controlled by the extra function of the controller
- Refractory brick floor insulation for a higher floor load (Tmax 1700 °C)
- Lift door
- Automatic door lock incl. door contact switch
- Heating elements protected against mechanical damage
- Special heating element qualities e. g. for zircon oxide applications
- Ethernet interface
