Under effect, the polar molecule in dielectric material is orientated from original random distribution state shift by the polar alignment of electric field, is orientated
Movement is constantly changed with billions of frequency per second, to cause molecule strenuous exercise and collision friction, is generated heat, is made medium
Temperature constantly increases.Microwave has the characteristics such as penetrability, selection heating, homogeneous heating.Microwave has penetrability, reduces material and exists
The phenomenon that being seethed under traditional heating mode avoids generating a large amount of flue dust.Microwave has selection plus thermal property, and microwave is only to gold
Belong to oxide to be heated, and the unserviceable ore such as gangue is not heated, the energy is efficiently used.In addition, micro-
Wave to material heating be to material inside and outside simultaneously heat, to material heating it is relatively uniform, avoid traditional heating from outside to inside into
Row heating, avoids " cold " center " problem.
Microwave heating technique is applied to metallurgical industry, is the revolution of metallurgical technology, microwave metallurgical has energy saving, high
Imitate, be easy to automatically control, environmental protection the advantages that.But application of the microwave heating technique in metallurgical industry for now is also not
Enough maturations, still in laboratory or half industrial stage, there is also problems, such as the exploitation of large microwave equipment and corresponding
Auxiliary facility, the problems such as microwave metallurgical flow scheme design, has to be solved.
