How to maintain a high-temperature box type resistance furnace in daily life?

The daily maintenance of high-temperature box type resistance furnaces is the key to ensuring their long-term stable operation and extending their service life. Here are some specific maintenance measures:

1. Regular cleaning
Internal cleaning of furnace: After each use, wait for the resistance furnace to cool to room temperature and wipe the interior of the furnace with a clean soft cloth to remove residual debris, dust, and oxides. This helps to maintain the cleanliness of the furnace, improve heating efficiency and temperature uniformity.
Cleaning of furnace shell: Clean the dust and dirt on the furnace shell to keep the appearance of the equipment clean. This can not only enhance the overall aesthetics of the device, but also help reduce the potential impact of dust on the internal components of the device.

2. Check the heating element
Regularly check the connection of heating elements (such as electric furnace wires) for looseness, deformation, or damage. If found, it should be tightened or replaced in a timely manner to ensure the heating effect and safety.

3. Calibrate temperature sensor
Calibrate the temperature sensor according to the prescribed cycle to ensure accurate temperature display. Standard thermometers can be used for comparative calibration to improve the accuracy of temperature control.

4. Check the control system
Check if the buttons and switches on the control panel are working properly and if the display is clear. Ensure that the circuit connections of the control system are good, without looseness or short circuits. This helps ensure the normal operation and safety of the equipment.

5. Maintain sealing components
Check if the sealing gasket of the furnace door is intact, and replace it promptly if it is aged or damaged. Ensure the good condition of other sealing components to prevent heat loss and gas leakage. Good sealing performance helps maintain the stability of the furnace atmosphere and the uniformity of temperature.

6. Lubricate moving parts
Regularly add an appropriate amount of lubricating oil to the hinges, handles, and other moving parts of the furnace door to ensure smooth operation. This helps to reduce component wear and failure rates, and improve the service life of equipment.

7. Check the power supply circuit
Regularly inspect the power supply circuit for any damage or aging. Ensure that the plug and socket are securely connected without any poor contact. This helps prevent electrical faults and safety accidents from occurring.

8. Storage environment
Resistance furnaces should be stored in a dry and well ventilated environment to avoid moisture and corrosive gases. This helps to protect the internal components of the device and extend its lifespan.

9. Develop a regular maintenance plan
Develop a regular maintenance plan based on the actual usage of the equipment and manufacturer’s recommendations. Conduct a comprehensive inspection and maintenance of the equipment according to the plan to ensure its long-term stable operation and efficient operation.

10. Safety precautions
Before carrying out any maintenance and upkeep operations, it is essential to ensure that the equipment has been powered off and cooled down to prevent electric shock and burns. At the same time, wear appropriate protective equipment such as gloves, goggles, etc. to ensure the safety of operators.

In summary, the daily maintenance of high-temperature box type resistance furnaces involves multiple aspects, including regular cleaning, inspection of heating elements, calibration of temperature sensors, inspection of control systems, maintenance of sealing components, lubrication of moving parts, inspection of power lines, storage environment, and development of regular maintenance plans. By implementing these measures, the long-term stable operation and efficient work of the equipment can be ensured.
