Description
Technical Field

Background
The heat treatment is a process of heating a solid metal material or a workpiece in a certain medium to a certain temperature, holding the temperature for a certain time, and then cooling the material to room temperature or lower at a certain rate, thereby changing the microstructure of the material to control the performance. Numerous special heat treatment methods emerge by the introduction of various new technologies. The electrostatic field has a special effect on substances, and the performance of the metal material can be further controlled on the basis of the thermal effect by introducing the electrostatic field heat treatment into the traditional heat treatment process; moreover, the electric field heat treatment can reduce the heat preservation temperature and shorten the heat preservation time, thereby achieving the purposes of improving the heat treatment efficiency, saving energy and saving cost.
In order to facilitate the application of an electrostatic field to a material to be processed, the object of electric field heat treatment is mainly a plate with a flat surface, and the basic working principle is as follows: 2 equal-size metal sheets are symmetrically placed at equal intervals and then communicated to form an electrode, the other 1 sheet to be subjected to heat treatment is placed in the middle of the two sheets in parallel to form another electrode, and the two electrodes are communicated with a direct-current power supply, so that the treated sheet is under the action of a uniform electrostatic field. The application of the electrostatic field can be realized in a general-purpose heat treatment furnace, in addition to a customized and dedicated electric field heat treatment furnace. At the moment, the electrode plates are directly arranged in a hearth, and the adjacent electrode plates are isolated by a single mica plate or a plurality of small insulating cushion blocks with certain thickness. One mode of electric field application is that a metal plate, an isolation plate or block, a processed plate, the isolation plate or block and another metal plate are horizontally piled up in a hearth from bottom to top in sequence; the other mode is that the components are fixed outside the hearth through an additional constraint structure and then are integrally placed in the hearth. After the heating and heat preservation process is completed under the action of an electrostatic field, the plate to be processed in the first mode is clamped out from the upper and lower isolation plates or blocks by a clamping tool, other components are scattered in a hearth, the components need to be sorted before the next plate is subjected to electric field heat treatment, and the loading step is repeated; in the second mode, the processed plate is taken out of the hearth together with the constraint structure and then enters the next process of heat treatment, the constraint structure of the previous plate needs to be removed from the hearth before the next plate is subjected to electric field heat treatment, and the loading step is repeated. The two electric field applying methods have complex working procedures, more time consumption and more difficulty in continuous operation.
The applicant's invention patent application No. cn201611261895.x filed at 2016.12.30 proposes a plate material handling apparatus for electric field heat treatment, which can continuously and rapidly apply an electric field to a plate material, but the improvement of the efficiency of the electric field heat treatment is limited to the plate material handling process.
