Description

Technical Field

[0001] This invention relates to the field of ultra-high temperature furnace technology, and in particular to a box-type ultra-high temperature furnace system. Background Technology

[0002] With the rapid development of national research on materials such as ceramics, graphite, and graphene in recent years, the study of the mechanical properties of these materials in ultra-high temperature environments has become increasingly important. Currently, all existing ultra-high temperature furnaces on the market adopt a cylindrical split structure, with the left and right semicircles connected by hinges, and a rotating opening and closing mechanism. They generally use silicon molybdenum rods or silicon carbide rods as heating elements, and are powered by low-voltage, high-current power. Through actual installation testing and use, the following shortcomings have been found in the current ultra-high temperature furnaces on the market:

[0003] 1. Under ultra-high temperature conditions, the cylindrical split structure has high requirements for the machining accuracy of parts and assembly. The gap between the left and right semicircles must be small when they are closed, otherwise fire may easily occur, causing personal and property safety risks. In addition, the presence of gaps will affect the fluctuation of temperature control effect, and excessive heat loss from gaps will lead to energy waste due to excessive heat preservation power.

[0004] 2. Currently available ultra-high temperature furnaces do not support deformation measurement. In actual materials research, the deformation of a sample under tensile stress is an important experimental data point. The lack of this data will seriously affect the results of materials research.

[0005] 3. Due to the limited space of the test equipment, the insulation layer of the furnace body is not thick. In order to ensure the surface temperature of the furnace body, a water cooling layer is usually added to the outside of the furnace body. Currently, the water cooling layer and the furnace body are welded as a whole. Once a leak occurs, the whole thing needs to be disassembled for repair or replacement, which is not conducive to later maintenance.

[0040] In one embodiment, the top of the furnace body 101 is fixedly connected with a shell 49, and the outer side wall of the shell 49 is symmetrically provided with four second heat dissipation fans 50; the shell 49 is cooled by the second heat dissipation fans 50 to ensure the safety of the electrical parts in the shell 49.

[0042] In one embodiment, the door body 201 is fixedly connected with a positioning plate 56 symmetrically away from the middle of one side of the furnace body 101, and the inner side wall of the positioning plate 56 is slidably connected with a quartz glass plate 51; the deformation measurement window 202 is opened by moving the quartz glass plate 51 with the positioning plate 56, so as to install the extensometer of the deformation measuring instrument through the deformation measurement window 202.

[0043] In one embodiment, the inner side wall of the alumina hearth 102 is provided with a thermocouple detector 42 in the middle, the rear surface of the furnace body 101 is provided with a central control console 54, and the inner side wall of the alumina hearth 102 is fixedly connected with a hearth upper plug 53 at the top; the temperature data in the furnace body 101 is detected by the thermocouple detector 42.

[0044] In one embodiment, the display screen 55 is installed on one side of the furnace body 101 away from the central console 54, the signal output end of the central console 54 is electrically connected to the signal input end of the display screen 55 through a wire, the signal output end of the display screen 55 and the thermocouple detector 42 is electrically connected to the signal input end of the central console 54 through a wire, and the electrical output end of the central console 54 is electrically connected to the electrical input end of the heating body 206, the first heat dissipation fan 44 and the second heat dissipation fan 50 through a wire; the data of the thermocouple detector 42 is received by the central console 54, the data received by the central console 54 is displayed by the display screen 55, so that the staff can view the data, and the opening and closing of the heating body 206, the first heat dissipation fan 44 and the second heat dissipation fan 50 are controlled by the central console 54 according to the instructions input by the display screen 55.

[0045] In operation, this invention creates a test temperature field inside the furnace body 101 through the alumina furnace chamber 102. Then, a nano-insulation plate 103 is filled between the air layer 104 and the alumina furnace chamber 102. Due to the low thermal conductivity of the nano-insulation material, but its inability to withstand ultra-high temperatures, the alumina furnace chamber 102 provides initial insulation for the furnace body 101, followed by secondary insulation using the nano-insulation plate 103. This improves the insulation performance of the ultra-high temperature furnace. The material to be tested is placed within the test temperature field of the furnace body 101. Then, the door 201 is moved, causing the upper front door plug 45, middle front door plug 46, and lower front door plug 47 to contact the alumina furnace chamber 102. One side is fitted together to embed the upper front door plug 45, the middle front door plug 46, and the lower front door plug 47 into the furnace body 101, making the overall structure of the furnace body 101 more reasonable, eliminating gaps, improving the overall heat preservation effect, preventing fire spread, saving energy, and ensuring the personal safety of the test personnel. Then, the control commands are entered into the central control console 54 through the display screen 55. The central control console 54 then starts the second cooling fan 50 and the heating element 206 according to the commands. The heating element 206 performs ultra-high temperature heating treatment on the materials inside the furnace body 101, and then the second cooling fan 50 dissipates heat from the shell 49 to ensure the safety of the electrical components inside the shell 49. The temperature data inside the furnace body 101 is then detected by thermocouple detector 42. When the data detected by thermocouple detector 42 reaches the threshold, the heating element 206 is turned off via the central control panel 54, thus completing the ultra-high temperature treatment of the material. When deformation measurement of the material is required during the treatment process, the corresponding instruction is entered into the central control panel 54 via the display screen 55. Then, the first cooling fan 44 is started via the central control panel 54. The quartz glass plate 51 is moved and the deformation measurement window 202 is opened using the positioning plate 56. The extensometer of the deformation measurement instrument is then installed via the deformation measurement window 202 to allow for deformation measurement of the material during the treatment process, thereby enriching the experimental data. This greatly improves the situation of missing experimental data and ensures the progress of materials research. Then, the first heat dissipation fan 44 is used to dissipate heat and cool the extensometer of the deformation measurement instrument. When deformation measurement is not required, the deformation measurement window 202 is closed by moving the quartz glass plate 51. Then, the drawer-type water-cooled box 205 uses water to absorb the heat overflowing from the furnace body 101, thereby ensuring the surface temperature of the furnace body 101. When the drawer-type water-cooled box 205 needs to be maintained or replaced, only the water pipe joint on one side of the drawer-type water-cooled box 205 needs to be removed, and the drawer-type water-cooled box 205 can be directly taken out from the water-cooling layer 204 for replacement without the need for complete disassembly, which simplifies the disassembly and assembly steps.

[0046] The above merely illustrates the specific embodiments of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art can easily think of various changes or replacements within the technical range disclosed by the present application, which should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
