Prospects of the development of vacuum induction furnace

Vacuum induction furnace oxidation, decarbonization, surface brightness, small deformation, no pollution, energy saving, high degree of automation, as well as the advantages of wide scope of application, in recent years is one of the faster growing new technology of heat treatment, especially in the case of aviation materials surface modification gain great progress. Many of the new development of advanced heat treatment technology, such as vacuum high-pressure gas quenching, vacuum chemical heat treatment, etc., also need to implement at the bottom of the vacuum. The vacuum heat treatment technology can make the structure material, working mould quality and greatly improve the service life, especially suitable for some precision parts heat treatment.
With the development of the vacuum heat treatment technology, vacuum heat treatment equipment such as vacuum tempering furnace, vacuum heat treatment furnace, vacuum annealing furnace, vacuum carburizing furnace, vacuum sintering furnace, vacuum brazing furnace was successfully developed at home, such as vacuum furnace in industrial manufacturing technology and equipment level enhances unceasingly, vacuum degree has reached the international level, but in automation control and device on the precision processing of, there is still a gap with foreign, especially in ultrahigh vacuum furnace on the stability of performance remains to be the improvement of precision devices. In addition test technology and the development of measuring instruments also has a great influence of vacuum equipment, especially the automatic test and control technology. Limiting vacuum of vacuum equipment, vacuum degree of work, empty furnace fit time, pressure rise rate, furnace temperature uniformity and empty furnace heating time parameters such as accurate measurement, and performance is the main embodiment of vacuum furnace performance.
In the industrial developed countries, the proportion of the vacuum heat treatment furnace has reached about 20%, and about 1200 sets of vacuum heat treatment furnace in our country at present, about 1% of the total number of heat treatment furnace, and a big gap in foreign countries, is expected in the future, as the heat treatment industry technology progress and requirement for the quality of heat treatment of workpiece is higher and higher, the development of the vacuum heat treatment will be larger.
