How to solve the overheating alarm of multi gradient experimental tube furnace?

The solution to the over temperature alarm of the multi gradient experimental tube furnace mainly includes the following steps:

Confirm the reason for the alarm:
Firstly, check if the actual temperature of the furnace body has indeed exceeded the set safe temperature.
Confirm whether the temperature sensor is working properly and whether there is any damage or poor contact.
Check if the temperature controller is set correctly, and if there are any errors in operation or parameter settings.

Reduce furnace temperature:
If the temperature of the furnace body is indeed too high, the heating power should be immediately turned off to cut off the source of heat.
Fans or ventilation devices can be used to blow air around the furnace, increasing the air flow velocity and heat dissipation area around the furnace, thereby accelerating the dissipation of heat.
If conditions permit, it is also possible to consider using cooling liquids (such as water, cooling oil, etc.) to spray or circulate through the surface of the furnace body, rapidly reducing the temperature of the furnace body through the high thermal conductivity of the liquid. However, this method is complex to operate and carries certain security risks, and should be used with caution.

Check and repair faults:
If it is confirmed that the overheating alarm is caused by damage to the temperature sensor or temperature controller, the damaged components should be replaced in a timely manner.
Check whether the insulation material of the furnace body is intact. If it is damaged, it should be replaced in a timely manner to improve the insulation effect and reduce heat loss.
Conduct a comprehensive inspection of other components of the furnace body to ensure that there are no other potential safety hazards.

Adjust the parameters of the temperature control system:
Adjust the parameters of the temperature control system according to the actual situation, such as set temperature, heating rate, etc., to ensure that the furnace temperature can remain stable within the set range.
If the furnace body frequently experiences over temperature alarms, it is possible to consider increasing the temperature alarm threshold or adjusting the sensitivity of the alarm.

Prevent similar malfunctions from happening again:
Regularly maintain and upkeep the multi gradient experimental tube furnace, clean up the accumulated ash and debris inside the furnace, and keep the equipment in good condition.
Strictly follow the operating procedures and safety standards of the high-temperature experimental furnace to avoid excessive furnace temperature or other safety issues caused by improper operation.
Pay attention to monitoring the temperature changes of the furnace body during the operation process, and promptly detect and handle any abnormal situations.
