Key Spare Parts of Box Type Tempering Furnace & Replacement Cycle

The stable operation of a box type tempering furnace depends on various core spare parts. Consumable parts will age and wear after long-term high-temperature operation, which is the main cause of daily equipment faults. Mastering the service life and replacement cycle of key accessories can help users arrange maintenance plans in advance and avoid production shutdown losses.

1. Heating Resistance Wire

As the core heating component, the resistance wire directly determines the heating efficiency and maximum temperature of the furnace. The service life of conventional iron-chromium-aluminum resistance wire is 8-12 months, and the service life of high-grade nickel-chromium alloy resistance wire can reach 18-24 months. It needs to be replaced in time when local burnout and slow heating occur. We provide original heating elements matching all models of box tempering furnaces.

2. Thermocouple & Compensation Wire

The thermocouple is responsible for real-time temperature detection, and its average service life is 6-10 months. Long-term high-temperature corrosion will cause temperature measurement deviation and data fluctuation. Users need to replace it regularly and select accessories with matching graduation according to the furnace temperature range to avoid temperature control failure.

3. Furnace Door Sealing Strip

The high-temperature resistant silicone sealing strip is a vulnerable consumable. Frequent opening and closing of the furnace door and high-temperature aging will lead to deformation and air leakage. The recommended replacement cycle is 3-6 months. Timely replacement can reduce heat loss, save power consumption and prevent workpiece oxidation.

4. Temperature Controller & Electrical Components

The intelligent PID temperature controller has a long service life of more than 3 years under normal use. Common faults include parameter disorder and display failure. The air switch and fuse belong to emergency protection parts, which need to be stored as spare parts and replaced immediately after damage to ensure equipment safety.
