Vacuum Ion Nitriding Furnace

Vacuum Ion Nitriding Furnace

The atmosphere of the furnace is even good. The furnace is well sealed and the exhaust gas is pumped through the vacuum pump to the rear of the sealed water tank. It is an energy-saving and environmental protection product.

Vacuum nitriding in vacuum nitriding furnace is carried out in a low vacuum state, and the atmosphere of each corner of the furnace can be kept fresh and active. The atmosphere of the furnace is even good. The furnace is well sealed and the exhaust gas is pumped through the vacuum pump to the rear of the sealed water tank. It is an energy-saving and environmental protection product.

Vacuum nitriding is dissolved into the ammonia to the vacuum furnace, vacuum nitriding was carried out on the workpiece, the work in a similar way to pulse type vacuum carburizing, namely the workpiece loading began after extraction, vacuum furnace when vacuum after reaching the set value, the furnace electricity to heat up, vacuum at the same time, to keep the furnace vacuum degree.

When the furnace temperature reaches the nitriding temperature, the function is to purify the surface of the workpiece and to clear the heat. After that, the vacuum is stopped and the nitrous oxide gas is injected into the furnace, so that the furnace pressure is raised to a certain value, which is maintained for a period of time, and then the vacuum is removed and maintained for a period of time. Nitride gas; Thus, repeated several times until the nitriding depth reaches the required level. The furnace temperature remains the same throughout the whole process.

Characteristics of vacuum nitriding furnace:

1. The heating element is evenly arranged along the circumference of the heating chamber, with a high temperature uniformity;

2. Separation of heating chamber and cooling chamber, high production efficiency and low cost of use;

3. Good cooling uniformity and small deformation of workpiece;

4. The nitriding gas nozzle is evenly arranged along the circumference of the heating chamber, and the thickness of the nitriding layer is uniform;

5.Simple operation, flexible programming, stable and reliable mechanical operation;
