Technical Support
Roller Hearth Kiln (RHK) is a continuous firing furnace which transports products using ceramic rollers.
RHK provides outstanding temperature uniformity, cleanliness and heat efficiency.
Uniform Temperature Distribution
RHK's roller transportation method makes radiant heating from all direction possible and narrows temperature distribution to ±2°C.
High Speed Firing
NORITAKE adopts Spring Drive method for the roller transportation drive.
This allows for high speed transfer without meandering.
Example of high speed Firing
| Work | Alumina substrate | Thermistor |
LCO |
BTO |
|---|---|---|---|---|
| Temp. | 1600℃ | 1300℃ | 1000℃ | 1200℃ |
|
Firing time of RHK |
6h | 10h | 12h | 6h |
|
Firing time of traditional kiln |
36h | 24h | 24h | 18h |
Clean Atmosphere
-
RHK materials are composed of ceramics which helps maintain a clean atmosphere.
Energy Saving and Space Saving
The combination of uniform heating and high speed firing realize high efficient production energy saving and space saving.
