The temperature range of electric heating vacuum annealing furnaces is usually wide, depending on the equipment model, design specifications, and the materials being processed. Generally speaking, the temperature range of electric heating vacuum annealing furnaces can cover temperatures from several hundred degrees Celsius to 2000 ℃ or even higher.

Specific temperature range analysis:

Low temperature range: The minimum operating temperature of some vacuum furnaces can reach 200 ℃, which is mainly used for some special low-temperature heat treatment processes, such as low-temperature annealing and low-temperature quenching.

Medium temperature range: usually between several hundred degrees Celsius and one thousand degrees Celsius, this temperature range is suitable for heat treatment of various materials, such as annealing and tempering of metal materials.

High temperature range: The maximum operating temperature of an electric heating vacuum annealing furnace can reach up to 2000 ℃ or even higher. The heat treatment processes at high temperatures include high-temperature annealing, high-temperature solid solution treatment, etc. These processes are very important for improving the performance of materials and increasing their service life.

Influencing factors:

Heating elements: Heating elements of vacuum furnaces, such as silicon carbon rods, silicon molybdenum rods, resistance furnace wires (such as tungsten wires), etc., their performance and temperature resistance range will affect the maximum operating temperature of the vacuum furnace.

Furnace material: The high temperature resistance and thermal stability of the furnace material are also important factors determining the temperature range of the vacuum furnace.

Vacuum system: The performance of the vacuum system will affect the heat conduction and radiation efficiency inside the furnace, thereby affecting temperature distribution and uniformity.

Example description:

Common models: Some common electric heating vacuum annealing furnace models may have a temperature range of 1000 ℃, 1200 ℃, 1400 ℃, 1600 ℃, 1700 ℃, 1800 ℃, and other options.

Special applications: Some high-end vacuum furnaces can be heated to 2100 degrees Celsius or even 2300 degrees Celsius, and these furnaces are typically used for special processes that require extremely high temperatures, such as melting and heat treatment of high-temperature alloys.
