- Gradual Heating – Increase the furnace temperature slowly by gradually raising the voltage. Do not exceed the safe temperature to avoid damaging the heating elements.
- Avoid Vibration – Do not subject the furnace to strong vibrations during operation, as red-hot heating wires are brittle and can break easily.
- Keep Dry – Ensure the furnace is not exposed to moisture to prevent electric leakage.
- Handle Thermocouples Carefully – When placing materials into the furnace, avoid touching the thermocouple. The hot end of the thermocouple inside the furnace can break easily at high temperatures.
- Avoid Reactive Chemicals – Do not place acidic, alkaline, or strong oxidizing chemicals inside the furnace. Never heat materials with explosion risks.
- Use Appropriate Containers – When heating metals or other minerals, place them in high-temperature resistant porcelain crucibles or dishes, or on refractory plates/asbestos boards, to prevent adhesion to the furnace chamber.
These measures ensure safe operation, protect the furnace components, and maintain stable heating performance.
