Vacuum quenching series equipment includes seven categories: 5.1 horizontal double chamber oil quenching type, 5.2 vertical double chamber oil quenching type, 5.3 horizontal double chamber gas quenching type, 5.4 horizontal single chamber gas quenching type, 5.5 vertical single chamber gas quenching type, 5.6 horizontal double chamber water quenching type, 5.7 vertical double chamber water quenching type;
Main applications of vacuum quenching furnace:
It is mainly used to cool the heated metal materials under vacuum or inert gas. The medium used for quenching is high-purity inert gas injected after vacuumizing, as well as vacuum quenching oil and water-based solvent. The vacuum quenching furnace can also realize the molding, surface finish treatment, precipitation hardening, vacuum annealing and other processes of high-speed steel and other steels.
Main advantages of vacuum quenching 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 quenching furnace:
Under vacuum and inert gas protection, the quenching process realized in conventional quenching furnace is completed in a fully automatic manner.
Vacuum quenching production line:
The skip car system can be configured to form a production line with multiple vacuum quenching furnaces, vacuum tempering furnaces, various cleaning machines and other equipment to meet the production needs of mass quenching.
Examples of photos of various types of equipment of vacuum quenching furnace are as follows:

Take the category "5.2 vertical double chamber oil quenching type, 5.7 vertical double chamber water quenching type" as an example to list the main parameters of the 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.
