Abstract
Description
Technical Field
[0001] The present application relates to the technical field of resistance furnaces, and in particular to a furnace plate of a resistance furnace. Background Art
[0002] Usually, multiple square furnace bottom plates need to be laid in the resistance furnace to support the workpiece. Since the furnace bottom plates will be heated at high temperature in the resistance furnace, in order to prevent the furnace bottom plates from squeezing and deforming each other and affecting production, expansion joints need to be left between two adjacent traditional furnace bottom plates during installation.
[0003] However, in the actual production and processing process, since metals will always produce a certain amount of oxidation when heated in a high-temperature oxidizing atmosphere, the oxide scale formed on the surface of the workpiece after oxidation will inevitably fall off and fall into the expansion joint under the transfer, external force, its own action and temperature changes, which can easily cause a short circuit in the electric heating element under the furnace plate, requiring frequent maintenance and cleaning. Utility Model Content
[0004] In order to reduce the phenomenon that oxide scale falls along the gap of furnace plate and affects the normal use of electric heating elements, the present application provides a furnace plate of a resistance furnace.
[0005] The present application provides a resistance furnace plate, which adopts the following technical solution:
[0006] A resistance furnace plate comprises a first furnace plate and a second furnace plate, wherein a first overlapping portion is formed on the first furnace plate, and a second overlapping portion is formed on the second furnace plate, and the first overlapping portion can be overlapped on the second overlapping portion.
[0007] By adopting the above technical solution, the first furnace plate and the second furnace plate together constitute the furnace plate structure above the resistance furnace, and when in use, the first overlapping portion of the first furnace plate will abut against the second overlapping portion of the second furnace plate, thereby sealing the gap between the first furnace plate and the second furnace plate through the overlap, effectively reducing the phenomenon of oxide scale falling along the furnace plate gap and affecting the normal use of the electric heating element.
[0008] Preferably, the first overlapping portion includes a first receiving section formed on the first furnace plate and a first hook section formed on the first receiving section.
[0009] By adopting the above technical solution, through the arrangement of the first receiving section and the first hook section, the first receiving section is used to receive the fallen oxide scale and leave space for the expansion joint, and the first hook section is used to prevent the oxide scale from falling and facilitates positioning and installation with the second furnace plate.
[0010] Preferably, the first receiving section is provided with a chamfer.
[0011] By adopting the above technical solution and setting the chamfer, the corner position on the first receiving section is eliminated, so that when the oxide scale falls into the receiving section, it will not remain in the corner and make it difficult to clean it later.
[0012] Preferably, the second overlapping portion includes a second receiving section formed on the second furnace plate and a second hook section formed on the second receiving section.
[0013] By adopting the above technical solution, through the arrangement of the second receiving section and the second hook section, the second receiving section is used to give way to the first hook section, and the second hook section is used to abut against the first hook section, so as to facilitate positioning and installation with the first furnace plate.
[0014] Preferably, the second receiving section is provided with a chamfer.
[0015] By adopting the above technical solution and setting the chamfer, it is convenient for the first hook section to be inserted into the second receiving section.
[0016] Preferably, the first furnace plate and the second furnace plate have the same height, the first receiving section and the second receiving section are staggered, and the second hook section can be inserted between the first furnace plate and the first hook section and abut against the first hook section.
[0017] By adopting the above technical solution, the first furnace plate and the second furnace plate have the same height, so the overall plane can be leveled, which is convenient for placing items, and the first receiving section and the second receiving section are staggered, which facilitates the staggered overlap of the first furnace plate and the second furnace plate.
[0018] Preferably, the width of the second hook section is smaller than the width of the first receiving section, and the width of the first hook section is smaller than the width of the second receiving section.
[0019] By adopting the above technical solution, the width of the second hook section is smaller than the width of the first receiving section, so that when the second hook section is inserted into the first receiving section, a certain gap will be formed between the second hook section and the first furnace plate, thereby retaining the expansion gap and the gap when the furnace plate expands due to heat.
[0020] Preferably, the height of the second hook section is less than or equal to the height of the first furnace plate minus the height of the first receiving section.
[0021] By adopting the above technical solution, the abutment between the first hook section and the second hook section is facilitated.
[0022] In summary, the present application includes at least one of the following beneficial technical effects:
[0023] 1. Through the arrangement of the first receiving section, the first hook section, the second receiving section and the second hook section, the first hook section can be inserted above the first receiving section and abut against the first hook section, thereby connecting the first furnace plate with the second furnace plate, and the gap between the original first furnace plate and the second furnace plate is blocked by the first receiving section and the second receiving section, and the fallen oxide scale is received, which effectively reduces the oxide scale falling along the furnace plate gap and affecting the normal use of the electric heating element;
[0024] 2. The width of the second hook section is smaller than that of the first receiving section, and the width of the first hook section is smaller than that of the second receiving section, so that when the second hook section abuts against the first hook section, there is still a gap between the first hook section and the first furnace plate, and there is still a gap between the second hook section and the second furnace plate, thereby retaining the gap between the first furnace plate and the second furnace plate, thereby retaining the position required for the furnace plate to expand due to heat.

[0028] The following is combined with Figure 1 -Attached Figure 2 This application is described in further detail.
[0029] The embodiment of the present application discloses a furnace plate of a resistance furnace.
[0030] like Figure 1 and 2 As shown, a resistance furnace plate includes a first furnace plate 1 and a second furnace plate 2, the first furnace plate 1 and the second furnace plate 2 are both square, a first overlap portion 3 is formed on one side of the first furnace plate 1, the first overlap portion 3 includes a first receiving section 31 and a first hook section 32, the first receiving section 31 and the first hook section 32 make the first overlap portion 3 as a whole L-shaped connected to the first furnace plate 1, and the first receiving section 31 is provided with a chamfer, the height of the first hook section 32 is less than the height of the first furnace plate 1, the height of the first receiving section 31 is less than the height of the first hook section 32, the first hook section 32, the first furnace plate 1, and the first receiving section 31 work together to form a groove structure above the first receiving section 31.
[0031] like Figure 1 and 2 As shown, the height of the second furnace plate 2 is the same as that of the first furnace plate 1, and a second overlapping portion 4 is formed on one side of the second furnace plate 2. The second overlapping portion 4 includes a second receiving section 41 and a second hook section 42. The second receiving section 41 and the second hook section 42 make the second overlapping portion 4 as a whole L-shaped and connected to the second furnace plate 2, and a chamfer is provided on the second receiving section 41. The height of the second hook section 42 is less than the height of the second furnace plate 2, and the height of the second receiving section 41 is less than the height of the second hook section 42. The second hook section 42, the second furnace plate 2, and the second receiving section 41 work together to form a groove structure above the second receiving section 41.
[0032] like Figure 1 and 2 As shown, the first receiving section 31 is formed along the lower side of the first furnace plate 1, and the second receiving section 41 is formed along the upper side of the second furnace plate 2. When the first furnace plate 1 and the second furnace plate 2 are placed in the same plane, the first receiving section 31 and the second receiving section 41 are staggered, and the height of the second hook section 42 is less than or equal to the height of the first furnace plate 1 minus the height of the first receiving section 31. The height of the first hook section 32 is also less than or equal to the height of the second furnace plate 2 minus the height of the second receiving section 41, and the first hook section 32 can abut against the second hook section 42. The width of the second hook section 42 is less than the width of the first receiving section 31, and the width of the first hook section 32 is less than the width of the second receiving section 41, thereby reserving sufficient expansion gap. When in use, the first furnace plate 1 and the second furnace plate 2 are moved in sequence to seal the upper cover of the resistance furnace, and the second hook section 42 is inserted into the groove structure formed by the first hook section 32, the first furnace plate 1, and the first receiving section 31. At this time, the first hook section 32 will also be inserted into the groove structure formed by the second hook section 42, the second furnace plate 2, and the second receiving section 41. Then the first furnace plate 1 and the second furnace plate 2 are moved so that the first furnace plate 1 and the second furnace plate 2 move in a direction away from each other, so that the first hook section 32 is engaged with the second hook section 42, thereby completing the installation of the first furnace plate 1 and the second furnace plate 2. After installation, the second hook section 42 will abut against the first hook section 32 for limiting. When the oxide scale falls off, the oxide scale will fall into the first receiving section 31 for receiving, and will not fall off, affecting the normal use of the resistance furnace.
[0033] The implementation principle of the embodiment of the present application is as follows: when put into actual use, the first hook section 32 on the first furnace plate 1 will abut against the second hook section 42 of the second furnace plate 2, and an expansion gap is reserved between the second hook section 42 and the first furnace plate 1, and an expansion gap is also reserved between the first hook section 32 and the second furnace plate 2. When the oxide scale falls off, the oxide scale will fall onto the first receiving section 31 and will not fall directly into the resistance furnace below along the expansion gap, which effectively reduces the phenomenon of the oxide scale falling along the furnace plate gap and affecting the normal use of the electric heating element.
[0034] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
