Daily maintenance of box type resistance furnace

The daily maintenance of the box type resistance furnace is the key to ensuring its normal operation and extending its service life. Here are some suggestions for daily maintenance of box type resistance furnaces:

1. Storage environment requirements
Box type resistance furnaces should be stored in a dry, ventilated, and dust-free environment to avoid the erosion of moisture and corrosive gases.
The storage location should avoid vibration and direct sunlight to ensure the stability of the furnace and extend its service life.
It should be ensured that there is sufficient space around the furnace body for operation and heat dissipation.

2. Daily cleaning
After each use, wait for the furnace to cool down and wipe the outside of the furnace with a clean damp cloth to remove dust and stains.
Regularly clean the debris and dust inside the furnace, using a vacuum cleaner or soft bristled brush to gently remove them to avoid scratching the furnace with hard objects.

3. Heating element inspection
Regularly check whether the connection of heating elements (such as silicon carbide rods) is loose, and whether there is any damage, oxidation, or deformation on the surface.
If the heating element is found to be damaged, it should be replaced in a timely manner to ensure normal heating and temperature uniformity.

4. Temperature controller calibration
According to the equipment manual, regularly calibrate the temperature controller to ensure the accuracy of temperature display and control.

5. Sealing and insulation inspection
Check the sealing of the furnace door to ensure good sealing and prevent heat loss and external air from entering.
Check whether the insulation material is damaged or detached, and if so, repair or replace it in a timely manner to maintain good insulation performance.

6. Electrical connection inspection
Regularly check whether the electrical connections such as power lines and control lines are secure, and whether there are any damages, aging, or other phenomena.

7. Other precautions
When placing and removing samples, specialized tools should be used to avoid colliding with the furnace and heating elements.
Follow the operating procedures to avoid equipment damage caused by unauthorized operations.
Establish maintenance records, recording the time, content, problems discovered, and solutions for each maintenance, in order to track the maintenance history and status of the equipment.

8. Regular trial operation
Even during periods of non use, regular short-term trial runs should be conducted to check if the equipment is functioning properly.

In summary, the daily maintenance of box type resistance furnaces involves multiple aspects, including storage environment, daily cleaning, heating element inspection, temperature controller calibration, sealing and insulation inspection, electrical connection inspection, and other precautions. Through regular maintenance and upkeep, the normal operation and extended service life of the box type resistance furnace can be ensured.
