PRODUCT SPECIFICATIONS
Technical data
Furnace housing
The furnace housing is mounted on a tilting frame and fixed on an underframe. The furnace inclination can be adjusted with a manual/ mechanical/ hydraulic lifting device.
The rotary tube drive is done via a frequency-controlled three-phase motor. The lead time can be varied steplessly via speed and work angle of the rotary tube.
Insulation
The insulation mainly consists of energy saving ceramic fiber material and is designed, depending on application, for cyclic or continuous operation.
Insert tube
Depending on temperature and firing good, different materials for the rotary tube can be used:
- Metallic tubes up to 1250 °C
- Ceramic tubes up to 1800 °C
- Quartz glass tubes up to 1050 °C
- Graphite/ sapphire tubes up to 1900 °C
- Special materials for special applications (acid-resistant stainless steels, Mo, W)
In the insert tube different fittings for improvement of mixing, for prevention of caking, for avoidance of lump formation etc. can be realized.
Rotary tubes can be also realized as cooling tracks with indirect water cooling.
Gastight design
The gas flows in the rotary tube can be realized in direct current as well as in countercurrent.
Switch and control unit
- Safety controller for each heating zone for protection of heating and insulation
- 3-phase thyristor unit for power regulation
- Pre-transformer (if necessary)
- Operating hours counter
- PLC (e. g. Stange, Simatic, optional possible among others)
