Can a well crucible furnace be filled with gas?

　　Well type crucible furnaces can be designed as atmosphere well type crucible furnaces or vacuum well type crucible furnaces according to process requirements, both of which support the introduction of specific gases. The atmosphere well crucible furnace adjusts the composition and pressure of the atmosphere inside the furnace by injecting gases such as nitrogen, hydrogen, and oxygen, and is suitable for processes such as metal sintering and ceramic sintering; The vacuum well crucible furnace creates a low-pressure or vacuum environment by extracting gas from the furnace, and is suitable for high-temperature processing of metal materials, anaerobic testing, and other scenarios. Some models are also equipped with atmosphere composition measurement and control systems to ensure that the furnace environment meets process requirements.
