Vacuum Ion Nitriding Furnace|Ion-Nitriding|Vacuum furnace - Vacuum Furnace -SIMUWU Vacuum Solution!
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.
