Vacuum nitriding furnace is a common mechanical equipment. In recent years, with more and more nitriding treatment projects, vacuum nitriding furnace is used more and more widely. The vacuum nitriding furnace is also called well type vacuum pulse nitriding furnace, which is used for gas nitriding of various workpieces, steam treatment of high-speed steel, and especially suitable for desalination of stainless steel piston rings, slit, deep hole, and blind hole molds. What is the difference between it and ordinary nitriding furnace?

The process cycle of vacuum nitriding furnace is obviously shorter than that of conventional positive pressure nitriding. It is unnecessary to leave a distance for sealing production, so that the productivity and furnace loading are significantly improved, the furnace design is reasonable, the thermal efficiency is high, the heat treatment process is advanced, the cycle is short, and the energy saving effect is significant. The surface brightness and roughness of dies and workpieces are basically unchanged after treatment, while the gas nitriding of carbon steel parts in ordinary nitriding furnace is equipped with a drip device, but its heat treatment cycle is relatively long and its working efficiency is relatively low, which is the difference between vacuum nitriding furnace and ordinary nitriding furnace.
