Moreover, the prepared magnetron with characteristics of high gas tightness, a high vacuum degree, low sparking probability and stable performance enables various defects existing in the prior art to be overcome.

Description

technical field [0001] The invention relates to a magnetron, in particular to a 2450MHz high-power continuous wave magnetron and a preparation method thereof. Background technique [0002] Energy conservation and environmental protection are the basic national policies for sustainable economic development in my country. The energy consumption of my country's six high-energy-consuming industries has accounted for 77% of the total industrial energy consumption, of which 5 industries involve heating treatment. Microwave heating is a selective heating method that directly interacts with the material to be heated. It has the characteristics of high efficiency, cleanliness and energy saving. The use of microwave heating to replace traditional heating in chemical and metallurgical industries can greatly improve the utilization rate of energy and achieve energy saving and reduction. purpose of the row. At present, in the 2450MHz frequency band in China, the microwave output power ...
