In vacuum smelting industry, high vacuum environment is the key to ensure product quality, and vacuum diffusion pump oil plays an indispensable role in this process.
Vacuum smelting requires reducing the pressure in the furnace to an extremely low level to prevent the metal from being oxidized at high temperature, while removing impurities and gases to improve the purity of the metal. Vacuum diffusion pump oil has the characteristics of high boiling point and low saturated vapor pressure, which makes it not easy to volatilize at high temperature and can maintain high vacuum continuously and stably. When the smelting furnace is started, the vacuum diffusion pump oil is heated, and the oil vapor generated is sprayed at high speed through the nozzle, continuously taking out the gas molecules in the furnace, thereby realizing the rapid establishment and maintenance of the vacuum environment.
In practical applications, whether it is the refining of rare metals or the smelting of special alloys, it depends on the efficient work of vacuum diffusion pump oil. Taking titanium alloy smelting as an example, it has extremely high requirements for vacuum degree, and the slightest impurity or oxygen mixed in will affect the performance of the alloy. The stable performance of vacuum diffusion pump oil ensures that the smelting process is always in an ideal vacuum state, helping to produce high-quality titanium alloy products. It can be said that vacuum diffusion pump oil is an important guarantee for the vacuum smelting industry to maintain efficient and stable production, and it plays an irreplaceable role in improving the quality and performance of smelting products.
