The temperature range of electric heating vacuum annealing furnaces is usually wide, which can be summarized as follows:

General temperature range:

600 ° C to 1300 ° C: This is a common temperature setting range for vacuum annealing furnaces, suitable for annealing various metal materials.

800 ° C to 1700 ° C: Some devices also use this range as their rated or operating temperature range, which can meet a wider range of material processing needs.

High temperature range:

Up to 2000 ° C or even higher: Some high-end or specially designed electric heating vacuum annealing furnaces can reach a maximum operating temperature of 2000 ° C, or even higher up to 2100 ° C or 2300 ° C, for special processes that require extremely high temperatures, such as melting and heat treatment of high-temperature alloys.

Low temperature range:

The lowest temperature can reach 200 ° C: mainly used for some special low-temperature heat treatment processes, such as low-temperature annealing and low-temperature quenching.

Influencing factors:

Heating elements such as silicon carbon rods, silicon molybdenum rods, resistance furnace wires, etc., their performance and temperature resistance range directly affect the maximum operating temperature of the vacuum furnace.

Furnace material: It needs to have high temperature resistance and thermal stability to withstand high temperature environments.

Vacuum system: affects the heat conduction and radiation efficiency inside the furnace, thereby affecting temperature distribution and uniformity.

Selection suggestion:

When selecting, the appropriate temperature range and heating method should be chosen based on the chemical composition of the material to be processed, the requirements of the heat treatment process, and production needs.

At the same time, consider factors such as the heating power, temperature control accuracy, vacuum degree, cooling method of the equipment, as well as the manufacturer's reputation and after-sales service.
