Regular inspection and evaluation: Regularly inspect the graphite electrode surface for wear, cracks and other damage. This can be done by visual inspection or using appropriate inspection tools. The inspection also includes measuring the size and shape of the graphite electrodes to ensure they meet specifications.

1. Repair or replace the damaged electrode: If the graphite electrode is found to be worn, cracked or otherwise damaged, repair or replace measures should be taken in time. Restoration can include filling the damaged area or repairing with specialized restorative materials. Seriously damaged or irreparable electrodes should be replaced in time to avoid further affecting the process and performance.

2. Cleaning and dust removal: It is very important to keep the surface of the graphite electrode clean. Regularly clean the graphite electrodes to remove the buildup of dust, impurities and chemicals on the surface. Cleaning can be done with appropriate cleaners and tools, avoiding the use of chemicals that can corrode or damage graphite electrodes.

3. Control temperature and current density: Reasonable control of the temperature and current density of graphite electrodes is the key to prolonging their life. Excessive temperatures and current densities may cause thermal stress and corrosion of graphite electrodes, shortening their service life. Make sure to operate under proper process parameters to avoid overloading the graphite electrodes.

4. Make maintenance plan and cycle: According to the actual situation, make a suitable maintenance plan and cycle. This includes regular inspection, cleaning and repair activities. Based on usage and life expectancy of graphite electrodes, determine the frequency and schedule of maintenance and follow the schedule.

5. Through effective life cycle management and maintenance, you can maximize the service life of graphite electrodes and ensure their stable and reliable performance. Keep in mind that each application and process may have specific maintenance requirements, so develop a management and maintenance plan that works for your specific situation and equipment.
