Can a well crucible furnace be evacuated?

There is a type of well crucible furnace called vacuum well crucible furnace, which extracts gas from the furnace chamber to create a low-pressure or even vacuum environment inside the chamber, in order to meet some special process requirements.For example, the vacuum well crucible furnace is suitable for testing, material processing, and heat treatment processes at high temperatures. The vacuum environment is crucial for certain high-temperature processes, such as high-temperature treatment of metal materials and testing under anaerobic conditions.

In addition, there is an atmosphere well crucible furnace, which adjusts the atmosphere composition and pressure inside the furnace chamber by injecting specific gases such as nitrogen, hydrogen, oxygen, etc., to meet different process requirements, such as metal sintering, ceramic sintering, heat treatment, etc.
