Vacuum annealing furnaces can be mainly divided into the following types based on their furnace structure and usage scenarios:

Horizontal vacuum annealing furnace:

Features: The furnace is manufactured as a fixed horizontal structure, which can be used in conjunction with heat treatment production lines. It is easy to install and operates efficiently.

Application: Mainly used for vacuum annealing, bright annealing, and vacuum heating of various mechanical parts and metal workpieces, especially suitable for annealing long shafts, plates, and other workpieces.

Vertical vacuum annealing furnace:

Features: Small footprint and compact structure.

Application: Suitable for batch processing of small workpieces, it can improve space utilization and production efficiency.

Well type vacuum annealing furnace:

Features: The furnace structure is similar to a well, and the workpiece can be placed vertically.

Application: Commonly used for annealing workpieces with depth requirements, such as vertical annealing of long axis parts, which can avoid bending deformation of workpieces during the annealing process.

In addition, there are some special purpose vacuum annealing furnaces, such as:

Multi purpose vacuum annealing furnace: It has a wider range of applicability and can be customized according to different material and process requirements.

Single crystal vacuum annealing furnace: specifically designed for annealing single crystals, it can accurately control the temperature and atmosphere during the annealing process, ensuring the quality and performance of single crystals.

Optical thin film vacuum annealing furnace: used for annealing optical thin films, which can improve the optical and mechanical properties of the films.

These different types of vacuum annealing furnaces have their own characteristics, and when selecting, it is necessary to comprehensively consider factors such as specific workpiece types, annealing process requirements, and production scale.
