Detailed Implementation
[0028] The following description, in conjunction with the accompanying drawings, further illustrates the specific implementation of a novel split-type high-temperature furnace according to the present invention. The novel split-type high-temperature furnace of the present invention is not limited to the description of the following embodiments.
[0029] like Figure 1-6 As shown, a novel split-type high-temperature furnace 1 of this embodiment has at least a furnace body 10. The furnace body 10 adopts a split structure, including a first furnace body part 100 and a second furnace body part 101 that are arranged in opposition. The first furnace body part 100 and the second furnace body part 101 are connected by a hinge 12. A furnace chamber 11 is provided inside the furnace body 10. The furnace chamber 11 has a furnace chamber cavity 110 for high-temperature material testing. The furnace chamber 11 also adopts a split structure, including a first furnace chamber 111 and a second furnace chamber 112 that are arranged in opposition. The first furnace chamber is correspondingly arranged with the first furnace body part 100, and the second furnace chamber is correspondingly arranged with the second furnace body part 101. A plug 14 is provided at both the upper and lower ends of the furnace chamber 11, and a pressure plate 15 is provided at both the upper and lower ends of the furnace body 10. The plug 14 is located between the pressure plate 15 and the furnace chamber 11.
[0030] More specifically: The first furnace body 100 and the second furnace body 101 have the same structure and are arranged opposite each other. The opposite sides of the first furnace body 100 and the second furnace body 101 are connected by a hinge 12, and the opposite sides are provided with a handle 13 to realize the opening and closing of the first furnace body 100 and the second furnace body 101.
[0031] The first furnace chamber 111 and the second furnace chamber 112 have the same structure. On the side of the first furnace chamber 111 and the second furnace chamber 112 that are opposite to each other, there are protrusions 113 and / or recesses 114 that are arranged along their height direction. The recesses 114 of the first furnace chamber 111 match the protrusions 113 of the second furnace chamber 112, and the protrusions 113 of the first furnace chamber 111 match the recesses 114 of the second furnace chamber 112. The matching and interlocking protrusions 113 and recesses 114 effectively prevent the intrusion of external air and ensure the stable heat preservation of the high-temperature furnace 1 during the test.
[0032] A heating structure 115 is provided inside the furnace chamber 11, forming an upper heating zone 1150, a middle heating zone 1151, and a lower heating zone 1152 along its height direction within the furnace chamber cavity. The upper heating zone 1150 and the lower heating zone 1152 are the main heating zones, while the middle heating zone 1151 is a heat equalization zone. In this embodiment, the heating structure 115 uses an electric heating wire. In actual use, other heating structures can also be used to achieve experimental heating. To match the installation of the electric heating wire, both the first furnace chamber 111 and the second furnace chamber 112 in this embodiment are provided with heating grooves 1154. The heating grooves are spirally arranged inside the first furnace chamber 111 and the second furnace chamber 112 to install electric heating wires and achieve heating of the furnace chamber cavity 110.
[0033] As the main heating zone, the electric heating wires of the upper heating zone 1150 and the lower heating zone 1152 are heated synchronously; at the same time, as the heat equalization zone, the first furnace chamber 111 and the second furnace chamber 112 located in the middle heating zone 1151 can also be provided with circulation holes 1153 to promote airflow in the furnace chamber cavity 110 and force convection to make the temperature distribution more uniform. In other embodiments, circulation holes 1153 are not a necessary design and heat equalization can also be achieved by electromagnetic field.
[0034] Both the upper and lower ends of the first furnace chamber 111 and the second furnace chamber 112 are provided with stepped mounting grooves 116. The plugs 14 are set on the mounting grooves 116 and are located at the upper and lower ends of the furnace chamber cavity 110. In this embodiment, the plugs 14 are semi-circular ring structures. The two plugs 14 installed in the first furnace chamber 111 and the second furnace chamber 112 are joined together to form a circular ring structure. The outer diameter of the joined plugs 14 of the circular ring structure is larger than the diameter of the furnace chamber cavity 110. In other embodiments, the plugs 14 can also adopt other structures, such as [-shaped structures].
[0035] The plug 14 has a test interface 140 at its center. The test fixture extends into the furnace cavity 110 through the test interface 140 to conduct high-temperature tests. The test fixture and test machine can adopt existing structures, which will not be described in detail here.
[0036] The furnace body 10 has cover plates 102 at both the top and bottom. The cover plates 102 are located on the outside of the plug 14. A notch 1020 is provided in the middle of the cover plate 102. The shape of the notch 1020 matches the shape of the plug 14. In this embodiment, the notch 1020 is an arc-shaped notch. The diameter of the arc-shaped notch 1020 is between the diameter of the test interface 140 of the plug 14 and the outer ring diameter, so that the cover plate 102 partially covers the outside of the plug 14 and completely covers the joint between the furnace chamber 11 and the furnace body 10.
[0037] The pressure plate 15 is disposed on the outside of the cover plate 102. The shape of the pressure plate 15 matches the shape of the plug 14. In this embodiment, the pressure plate 15 is an arc-shaped plate, and the inner diameter of the arc-shaped plate is equivalent to the inner diameter of the arc-shaped notch 1020 of the cover plate 102.
[0038] In addition, the pressure plate 15 also has a bending portion 150, and the plug 14 is provided with a groove 141. The bending portion 150 is embedded in the groove 141 to achieve effective fixation of the plug 14 by the pressure plate 15.
