Vacuum isothermal quenching series equipment includes three categories: 4.1 horizontal three chamber salt bath type, 4.2 vertical double chamber salt bath type, 4.3 horizontal single chamber gas quenching type;
Main applications of vacuum isothermal quenching furnace:
Isothermal quenching can significantly reduce the tendency of workpiece deformation and cracking, and is suitable for processing tools and important machine parts with complex shape and precise size requirements, such as molds, cutters, gears, etc; It can also realize vacuum quenching, vacuum annealing and other processes of high speed steel, tool and die steel, alloy structural steel.
Main advantages of vacuum isothermal quenching furnace:
Safety, environmental protection, no open fire, no explosion hazard;
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 isothermal quenching furnace:
Under vacuum and inert gas protection, the isothermal quenching process realized in conventional salt bath furnace is completed in a fully automatic manner. It can completely replace the traditional salt bath furnace and avoid the environmental pollution caused by the traditional salt bath furnace and the impact on the recognition of health.
Examples of photos of various types of equipment of quenching furnace are as follows:

The vacuum isothermal quenching series equipment takes the category "4.1 Horizontal three chamber salt bath type" as an example to list the main parameters of its current standard model equipment

Note:
1. 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 the personalized needs of customers. For example, the extreme vacuum degree can reach 10-4Pa or above, and the pressure rise rate can be better than 0.1Pa/h;
2. The former refers to salt bath, and the latter refers to gas quenching;
3. It can also design and manufacture various salt bath equipment for continuous production according to the actual needs of users.
