Post-Operation Cooling
After the completion of testing, the furnace must be allowed to cool gradually.
Ceramic work tubes are subject to thermal expansion when heated to high
temperatures, increasing in both length and diameter. Rapid changes in temperature
can cause stress upon the work tube material which may cause it to break; a process
known as thermal shock.
To mitigate the risk of thermal shock to the work tube, a cool down rate
no greater
than 5°C per minute
is recommended.
Note:
The customer is responsible for any damage to the furnace caused by
exceeding the recommended cool down rate.
Note:
Because the exact details of the customer's process are unknown,
it is not possible to account for process-specific wear to the work tube
material. The working life of the work tube is variable and depends
entirely on the operating temperatures, program ramp rates, and
properties of the materials being heated. Subsequently the work tube is
classed as a consumable item and is not covered by the standard
Carbolite Gero warranty terms.
