High pressure gas nitriding (including nitrocarburizing) multi-functional vacuum series equipment mainly includes three categories: 2.1 horizontal double chamber oil quenching type, 2.2 horizontal single chamber gas quenching type, 2.3 vertical single chamber gas quenching type;
High pressure gas nitriding (including nitrocarburizing) multi-functional vacuum furnace is mainly used for:
It is applicable to various nitriding or nitrocarburizing products or parts with high added value and high treatment quality requirements, such as high-pressure gas nitriding, nitrocarburizing and tempering processes of molds, measuring tools, cutting tools, shafts and other parts; And vacuum quenching and vacuum annealing of high-speed steel, tool and die steel, alloy structural steel, etc.
Main advantages of multi-function vacuum furnace for high-pressure gas nitriding (including nitrocarburizing):
Safety, environmental protection, no open fire, no explosion hazard; Fully sealed vacuum furnace structure, little nitriding treatment site in the workshop, no ammonia smell;
Good production flexibility, can stop and open the furnace at any time;
Direct heating: the structure of vacuum heating furnace is adopted, and the heating element directly heats the parts, saving energy and time, and increasing and decreasing the temperature quickly;
High pressure in nitriding chamber: high pressure structure, ammonia pressure of 4 × 10-1～5 × Adjustable within 105Pa; Small hole, deep hole and blind hole can all get uniform infiltration layer, and the depth and hardness are similar to the external surface;
Fast cooling: high pressure air cooling, oil cooling; It can prevent temper brittleness of alloy structural steel caused by slow cooling at nitriding temperature, and eliminate the bad structure of carburizing layer, such as acicular precipitation;
After treatment, the surface quality of the workpiece is good and the deformation is small;
Less atmosphere consumption, short carburizing cycle and low production cost;
Process Control of High Pressure Gas Nitriding (including Zizania Carburizing) Multifunctional Vacuum Furnace
The process program inventory stores the high-pressure gas nitriding process program generated in advance by the process simulation system according to material composition, penetration depth, etc. and verified by production practice; The control system automatically and accurately controls the nitriding temperature, gas pressure, gas flow, etc. according to the program to ensure that the requirements of nitriding or nitrocarburizing process are met.
High pressure gas silencing (including nitrocarburizing) multi-functional vacuum production line
A skip car system can be configured to form a production line with multiple vacuum high-pressure gas nitriding furnaces, vacuum tempering furnaces, various cleaning machines and other equipment to meet the production needs of mass nitriding or nitrocarburizing.

      High pressure gas nitriding (including nitrocarburizing) multi-function vacuum series equipment Take category "2.2 horizontal single chamber gas quenching type" as an example, list 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.
