Description
Technical Field
The utility model relates to a but microwave heating device of rotation and revolution belongs to microwave high flux high temperature heating technical field.
Background
Heat treatment refers to a hot metal working process in which a material is heated, held, cooled, etc. in the solid state to achieve a desired texture and properties. The heating temperature is one of important process parameters of the heat treatment process, and the selection and control of the heating temperature are important problems for ensuring the heat treatment quality; the heating temperature varies depending on the metal material to be treated and the purpose of the heat treatment. But is generally heated above the transformation temperature to achieve a high temperature texture. In addition, the phase transformation requires a certain time, so when the surface of the metal workpiece reaches the required heating temperature, the temperature is kept for a certain time to keep the internal and external temperatures consistent.
Traditional heating methods are through heating material surrounding environment or its surface, wait to make the inside intensification of material through heat transfer behind the material surface temperature rise to realize the bulk heating of material, this heating methods have characteristics such as inefficiency, homogeneity are poor, the instantaneity is poor. The microwave heating is based on a dielectric theory, utilizes the characteristic that microwaves have the electromagnetic loss material to penetrate through, directly converts electromagnetic energy into heat energy and generates heat at the core inside a sample, and has the advantages of instantaneity, integrity, energy conservation, high efficiency, safety, harmlessness and the like due to the special heating principle.
The microwave heating is a heating mode of injecting microwaves into a medium to convert microwave energy into heat energy, so that the temperature of the microwave heating is integrally raised, the microwave heating is uniform in heating and fast in speed, and therefore, the microwave heating has the advantages of being less in heat loss, instantaneity, integrity, energy-saving, efficient, safe, harmless, pollution-free and the like.

firstly, the heat treatment temperature field is not uniform. The heat treatment furnace is generally in a resistance heating mode, and due to the fact that the space of a hearth is large, the temperature field in the hearth is not uniform, different heat treatment effects of samples placed in the hearth are not uniform, and the uniformity of heat treatment temperature is seriously affected.
And secondly, fixing the heat treatment device. The fixation of the heating device is one of the reasons for uneven heating of the material. The existing heat treatment method is that the material can only be heated locally in the heating process, so that the heated material cannot achieve the expected heating effect.
Microwave heating is a heating method that generates heat through the interaction between microwave radiation and a material based on the electromagnetic properties of the material. Compared with the traditional heating mode, the microwave heating has the advantages of volume heating, non-contact heating and selective heating, can enable the heating rate to be faster, and has less influence on the surrounding environment, thereby effectively improving the production economy. On the other hand, the energy generated by the material in the microwave field is closely related to the dielectric property of the material, and the material with different wave absorption properties is selected as an experimental sample, so that a gradient temperature field is more favorably formed, and the heating treatment of various materials at different temperatures is realized at one time.
