The daily maintenance of customized tempering furnaces is the key to ensuring their long-term stable operation, extending their service life, and ensuring the quality of heat treatment. Here are some key maintenance measures and suggestions:
1. Electrical system maintenance
Regularly check the power supply circuit
Ensure that the power lines are securely connected without any damage or aging.
Check if the grounding wire is reliable to prevent electric shock accidents.
Clean electrical components
Regularly clean the dust and debris inside the control cabinet to prevent short circuits or poor contact.
Check whether the contacts of electrical components (such as contactors, relays, circuit breakers, etc.) are worn or eroded, and replace them promptly if necessary.
Calibration control system
Regularly calibrate temperature controllers, timers, and other control equipment to ensure their accuracy and reliability.
Check whether the alarm and protection functions of the control system are normal, and promptly handle any abnormalities.
2. Heating system maintenance
Check the heating element
Regularly check the working condition of heating elements (such as resistance wires, silicon carbide rods, silicon molybdenum rods, etc.) to ensure that they are not damaged or deformed.
If the heating element is found to be damaged, it should be replaced in a timely manner and ensure that the specifications of the new element are consistent with the original.
Clean the furnace
Regularly clean the furnace of oxides, residues, and other impurities to prevent them from affecting the heating effect and furnace life.
Check for cracks or damage on the inner wall of the furnace, and repair or replace if necessary.
Check the thermocouple
Regularly check the installation position and connection status of thermocouples to ensure accurate measurement of furnace temperature.
If the thermocouple is found to be damaged or the measurement is inaccurate, it should be replaced in a timely manner.
3. Maintenance of furnace body and sealing system
Check the structure of the furnace body
Regularly inspect the structural integrity of the furnace body, including the furnace door, furnace wall, furnace bottom, and other parts.
If deformation, cracks or damage are found in the furnace body, timely repair or replacement should be carried out.
Maintain the sealing system
Check the sealing performance of the furnace door to ensure that it can tightly fit the furnace body, preventing heat loss and external air from entering.
If the sealing strip is found to be aged or damaged, it should be replaced in a timely manner.
For vacuum tempering furnaces, it is also necessary to regularly check the sealing of the vacuum system to ensure that the vacuum degree meets the requirements.
4. Cooling system maintenance
Check the cooling water pipeline
Regularly check the connection status and water flow of the cooling water pipeline to ensure that there are no leaks or blockages.
If the water pipe is found to be aged or damaged, it should be replaced in a timely manner.
Clean the cooling water tank
Regularly clean the scale and debris in the cooling water tank to prevent them from affecting the cooling effect.
Check the quality of the cooling water, and replace it promptly if the water quality is poor.
5. Safety and operation maintenance
Train operators
Regularly provide safety training and operating procedures training to operators to enhance their safety awareness and operational skills.
Ensure that operators are familiar with the performance, characteristics, and operating methods of the tempering furnace.
Develop maintenance plan
Develop a detailed maintenance plan based on the usage and maintenance requirements of the tempering furnace.
Regularly maintain and upkeep the tempering furnace according to the maintenance plan to ensure that it is in good working condition.
Record maintenance status
Establish a maintenance record file, detailing the time, content, and replaced parts of each maintenance.
Through maintenance records, the usage history and maintenance status of the tempering furnace can be traced, providing reference for subsequent repairs and maintenance.
