1. If the furnace and heating elements are used for an extended period of time, it's important to monitor and control the temperature properly. The electric furnace should operate within its rated temperature range under normal conditions. 2. When operating the electric furnace for a long duration, it is recommended to keep the temperature at least 50°C below the rated maximum. This helps extend the life of the equipment and ensures safe operation. 3. Prolonged use without regular cleaning can lead to the accumulation of iron filings and scale inside the furnace. These impurities can significantly affect the performance and efficiency of the electric furnace. Make sure to clean the interior regularly to maintain optimal function. 4. When opening the furnace door, handle it gently to protect both the furnace mouth and the internal structure. Similarly, when moving workpieces in and out, be careful to avoid damaging the furnace or its components. 5. Pay special attention to the oxide layer on the surface of the heating elements. This layer plays a crucial role in protecting the element from damage caused by molten metal or metal vapor. Avoid exposing the heating elements to such conditions as much as possible. 6. Always ensure that the furnace is operated in a well-ventilated area and follow all safety guidelines provided by the manufacturer. Regular maintenance and proper handling will help prevent malfunctions and prolong the lifespan of your electric furnace.
