Tips for using electric resistance furnace

Proper heating and cooling operations are crucial when using a resistance furnace. After starting the equipment, avoid rapid, direct heating. Instead, heat in stages according to process requirements, allowing the heating elements and furnace chamber to gradually adapt to temperature changes. This reduces thermal shock and extends the equipment's lifespan. Similarly, when shutting down the furnace, allow it to cool naturally or slowly according to a programmed procedure to prevent sudden temperature changes that could cause furnace lining cracking or workpiece deformation. Pay attention to the impact of the charging method on heating efficiency. Workpieces should be arranged reasonably within the furnace, maintaining appropriate spacing to avoid overcrowding or obstructing heat flow channels, ensuring uniform temperature distribution. Workpieces of different materials or sizes should be processed in batches whenever possible to improve heating consistency and process stability.

During daily operation, make full use of the temperature control system for precise adjustments. Set a reasonable temperature curve according to process requirements and regularly calibrate thermocouples and temperature controllers to ensure accurate temperature measurements. During operation, carefully observe the working status of the resistance wire or heating elements, and address any abnormalities promptly to ensure the long-term stable and efficient operation of the resistance furnace.
