vacuum pump system in vacuum metallurgy
Using vacuum pump systems for a wide range of metals and their alloys to stop the vacuum metallurgy, vacuum distillation, ore and half products vacuum separation, metal compounds vacuum recovery, liquid steel vacuum degassing and refining outside the furnace, metal vacuum smelting, vacuum sintering, vacuum heat treatment, vacuum brazing and vacuum wait for a variety of solid phase bonding process.
The vacuum metallurgy industry has been widely used since the 1950s because the vacuum environment has a series of characteristics in the metallurgical process. First is vacuum environment material and chemical action between the residual gas molecules are tiny, therefore very suitable for ferrous metals, rare metals, ultra pure metals and their alloys, semiconductor materials, smelting and refining. Secondly, in a vacuum environment, the partial pressure of a single gas molecule can be reduced to the purpose of degassing refining of molten steel and deoxygenation of carbon in vacuum.
Vacuum environment also is another feature of it at a lower temperature, has stopped a certain reaction ability, in the same temperature, for example, some reaction process in the atmosphere is harder to stop, but is very easily under low pressure. This is the basic principle of vacuum compound synthesis and non-ferrous metal smelting.
