When operating an electric arc furnace (EAF), several important safety and operational precautions should be observed:
- Gradual Heating – Increase the voltage slowly to heat the furnace. Avoid exceeding temperature limits to prevent damage to heating elements.
- Minimize Vibrations – Do not shake or jolt the furnace; red-hot heating rods are brittle and can easily crack.
- Keep Dry – Avoid moisture exposure to prevent electric leakage.
- Protect Thermocouples – When placing materials inside, do not touch the thermocouple hot ends, as they can break under high temperatures.
- Avoid Hazardous Chemicals – Do not introduce acids, bases, strong oxidizers, or explosive materials into the furnace.
- Use Proper Containers – When heating metals or minerals, place them in high-temperature resistant ceramic crucibles, dishes, or on refractory boards/asbestos sheets to prevent sticking to the furnace.
Following these precautions ensures safe operation and prolongs the life of your electric arc furnace.
