Can the atmosphere tube furnace open the furnace door at high temperature?

It is not recommended to open the furnace door directly when the atmosphere tube furnace is in a high temperature state. The main reasons are as follows:
Furnace damage: Atmosphere tube furnace belongs to high-temperature instruments. When the temperature inside the furnace is high, directly opening the furnace door will cause a sharp change in the temperature difference between the inside and outside of the furnace. This thermal shock may cause furnace cracking, affecting the sealing and service life of the furnace.
Heating element damage: Directly opening the furnace door at high temperatures may also cause damage to the heating elements inside the furnace, as the heating elements may be damaged due to excessive thermal stress when suddenly exposed to cold air at high temperatures.
Safety hazard: The heat and radiation inside the furnace are very strong at high temperatures, and directly opening the furnace door may cause safety hazards such as burns to the operators.
Therefore, in order to protect the atmosphere of the tube furnace and ensure operational safety, it is recommended that the tube furnace be cooled to a lower temperature (such as around 600 degrees) before carefully opening the furnace door. At the same time, attention should be paid to observing the operating status of the equipment during the operation process. If there are any abnormal phenomena, the machine should be stopped and checked in a timely manner. In addition, regular maintenance and upkeep of the atmosphere tube furnace is also an important measure to ensure its normal operation and extend its service life.
In summary, it is not recommended to open the furnace door directly when the atmosphere tube furnace is in a high temperature state. It should wait for it to cool to an appropriate temperature before operation.
