The development of the vacuum heat treatment and its prospect

Vacuum heat treatment is to point to the metal parts in a vacuum or vacuum before they are inert gas under the condition of heating, and then quenching cooling technology in the oil or gas. Because the vacuum heat treatment, the workpiece basic oxidation, steel decarburization, use air convection heating method still can make uniform heating, reduce the temperature difference between the surface and center and thus reduce the distortion. Now it has become a high quality mould and indispensable preferred heat treatment process. More valuable is that vacuum heat treatment in the process of production material won't produce any pollution environment, to be generally accepted belong to the category of cleaner production technologies. It is no exaggeration to say, vacuum heat treatment has become the main sign of advanced heat treatment production technology.
The current development of vacuum heat treatment is the main characteristic of convection heating and high pressure gas quenching, acetylene low pressure carburizing, ion carburizing, carburizing and other aspects. In order to make the heat treatment of the counterpart in the production of technical reformation can correctly understand and return to the development trend of vacuum heat treatment, thus can choose appropriate, the popularization and application.
