Ceramic band heater steatite insulation parts Alumina strips
Ceramic band heater steatite insulation parts Alumina strips
1 hole – 12 holes ceramic strips for ceramic band heaters
Material:
- white steatite
- pink alumina
Description:
Ceramic band heaters are structured with high-quality resistance wires(such as nichrome wires or Fe-Al-Cr alloys) embeded within ceramic strips. The ceramic strips are installed within the outer cover selection of stainless steel.
The middle of the selection of high-temperature ceramic fiber insulation, which effectively avoids the temperature leakage.
Ceramic band heater is a high-frequency ceramics, which has the advantages of fast heat transfer efficiency, hard and not easily broken, high-temperature deformation, not easy to aging.
