Vacuum annealing series equipment includes three categories: 6.1 horizontal double chamber type, 6.2 horizontal single chamber type, 6.3 vertical single chamber type;
Main purposes of vacuum annealing furnace:
Annealing is a metal heat treatment process, which refers to slowly heating the metal to a certain temperature, holding it for enough time, and then cooling it at an appropriate rate; The purpose is to reduce hardness and improve machinability; Eliminate residual stress, stabilize size, reduce deformation and crack tendency; Refine the grain, adjust the structure and eliminate the structural defects.
Main advantages of vacuum annealing furnace:
Safety and environmental protection;
Good production flexibility, can stop and open the furnace at any time;
The surface quality of the workpiece is good, and the processing deformation is small;
High degree of equipment automation;
Low equipment maintenance cost.
Process control of vacuum annealing furnace:
The vacuum annealing furnace can complete the annealing process under vacuum or inert gas protection, which can effectively avoid the surface oxidation and rust of the workpiece during the annealing process, and improve the processing quality;
Examples of photos of various types of equipment of vacuum annealing furnace are as follows:

The vacuum annealing series equipment takes the category "6.3 vertical single chamber type" as an example, and lists the main parameters of its current standard model equipment

Note:
The above are the parameters of our standard equipment. Shenyang Dongbo can carry out non-standard design and manufacturing according to the specific requirements of customers to meet their personalized needs. For example, the extreme vacuum degree can reach 10-4Pa or above, and the pressure rise rate can be better than 0.1Pa/h.
