The daily maintenance of high-temperature atmosphere furnaces is the key to ensuring their long-term stable operation and extending their service life. Here are some important maintenance measures:
1. Regular inspection and cleaning
Furnace cleaning:
Regularly clean the residue and impurities in the furnace to prevent damage to the heating elements and furnace body.
Vacuum pump pre vacuuming method or protective gas replacement method can be used for furnace cleaning to maintain the cleanliness and atmosphere requirements inside the furnace.
Cleaning of furnace surface:
Regularly remove dirt, oxides, and other pollutants from the surface of the furnace body to ensure good contact between the thermocouple and the furnace body.
Appropriate cleaning agents can be used during cleaning, but care should be taken to avoid corrosion of the furnace body.
2. Component inspection and maintenance
Heating element:
Regularly check whether the fastening bolts at the wire joints of the heating element are loose, and tighten them in a timely manner if necessary.
Check if the radiation heating tube is bent or damaged, and replace it immediately to prevent short circuit accidents caused by bending.
Sealing components:
Regularly check the sealing condition of all sealing parts (such as furnace doors, observation windows, etc.) to ensure no leakage.
If aging, cracking, or improper installation of seals is found, they should be replaced or adjusted in a timely manner.
Thermocouple:
Install the thermocouple correctly, ensuring that it is securely fastened and perpendicular to the surface of the furnace to ensure good contact.
Regularly check the installation status and surface condition of thermocouples. If there are problems such as oxidation, wear, or poor contact, they should be repaired or replaced in a timely manner.
Fan and control system:
Regularly check the operation of the fan, and if there are any abnormal phenomena, repair or replace them in a timely manner.
Check the control circuit board, display screen, control buttons and other control system components to ensure their normal operation.
3. Electrical system inspection
Check electrical components such as power cords, cables, plugs, switches, etc. to ensure that there is no damage, looseness, or aging.
Check if the control circuit board and sensors are working properly, and replace them promptly if there are any faults.
4. Air system inspection
Check the gas supply pipeline, valves, pressure gauges and other components of the gas system to ensure no leaks, flexible valve opening and closing, and accurate pressure measurement by the pressure gauge.
If necessary, clean and maintain the pneumatic system to keep it unobstructed.
5. Vacuum system inspection
Check the vacuum system components such as vacuum pump, vacuum pipeline, and vacuum valve to ensure that the vacuum pump is working properly, the vacuum pipeline is leak free, and the vacuum valve is open and closed flexibly.
Regularly maintain and upkeep the vacuum system to improve its efficiency and stability.
6. Training and Recording
Provide professional training to operators to improve their understanding and operational skills of high-temperature atmosphere furnace equipment.
Record in detail the inspected parts, problems discovered, and solutions during daily maintenance for easy archiving and subsequent reference.
In summary, the daily maintenance of high-temperature atmosphere furnaces involves multiple aspects, including furnace cleaning, component inspection and maintenance, electrical system inspection, gas system inspection, vacuum system inspection, and training and recording. Through scientific maintenance measures and strict operating procedures, the long-term stable operation and extended service life of high-temperature atmosphere furnaces can be ensured.
