High-temperature ceramic sintering furnaces are important heating equipment in industrial applications. Correct and reasonable use of laboratory furnaces and high-temperature furnaces can ensure optimal performance and extend their service life. The usage differences are as follows:
- Prohibit Pouring Liquids or Easily Soluble Metals into the Furnace: Doing so can damage the interior of the furnace.
- Controller Environment Requirements: The controllers of laboratory electric furnaces and high-temperature furnaces must operate in environments with relative humidity below 85%, free of conductive dust, explosive gases, or corrosive gases.
- Optimal Operating Temperature: Laboratory and high-temperature furnaces should ideally work at temperatures at least 50℃ below their maximum rated temperature. Operating at or near the rated temperature ensures longer heating element life, while running at maximum temperature shortens furnace life.
- Initial Use or Reuse After Long-Term Shutdown: When using the furnace for the first time or after a long period of inactivity, preheating (“baking”) is required. The preheating time is usually more than four hours, with a stable temperature range of 200–600℃. During operation, the furnace temperature should never exceed the rated maximum to avoid burning the heating elements, and should not be too low either, as this reduces the effectiveness of the preheating. Preheating must follow the specified temperature and duration.
