[0028] The technical schemes in the embodiments of the present application will be clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments only represent some embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without any creative effort belong to the protection scope of the present application.

[0029] The core of the present application is to provide a magnesium alloy furnace mouth high-temperature sealing structure, which can solve the problems of furnace mouth fire leakage, steel structure failure and magnesium alloy furnace shutdown maintenance caused by the direct contact of the high-temperature flame in the furnace with the metal material furnace body panel. Another core of the present application is to provide a furnace body structure comprising the above-mentioned magnesium alloy furnace mouth high-temperature sealing structure.

[0030] Please refer to Figure 2 , Figure 2 It is a structural schematic diagram of the magnesium alloy furnace mouth high-temperature sealing structure provided by the present application.

[0031] The present application provides a magnesium alloy furnace mouth high-temperature sealing structure, comprising:

[0032] A first isolation piece 1 is used to wrap around the outer peripheral portion of the bottom end of the crucible flange 4 of the magnesium alloy furnace 3;

[0033] A second isolation piece 2 is used to be attached along the inner peripheral portion of the top of the furnace body panel 5 of the magnesium alloy furnace 3;

[0034] The contact surface of the first isolation piece 1 and the second isolation piece 2 is a conical surface, and both the first isolation piece 1 and the second isolation piece 2 are non-combustible heat insulation material pieces.

[0035] It should be noted that, in the operation process of the magnesium alloy furnace 3, since the high-temperature flame in the furnace directly contacts the metal furnace body panel 5, the furnace body panel 5 may be oxidized and damaged. Magnesium alloy is easy to oxidize at high temperature, especially in the presence of an open flame, the oxidation rate of the magnesium alloy will increase by 5 times. This oxidation phenomenon not only affects the service life of the furnace body panel 5, but also may cause the performance of the magnesium alloy furnace 3 to decrease, increasing the maintenance cost of the magnesium alloy furnace 3. The device sets the first isolation piece 1 and the second isolation piece 2, and both the first isolation piece 1 and the second isolation piece 2 are non-combustible ceramic fiber heat insulation material pieces, which can effectively reduce the phenomenon of the high-temperature flame in the furnace directly contacting the metal furnace body panel 5.

[0036] In actual application, the shape, structure, size, material, position, etc. of the first isolation piece 1 and the second isolation piece 2 can be determined according to actual conditions and actual needs.

[0037] When the magnesium alloy furnace mouth high-temperature sealing structure is used, the first isolation piece 1 wraps around the outer peripheral portion of the bottom end of the crucible flange 4 of the magnesium alloy furnace 3, and the first isolation piece 1 is a non-combustible heat insulation material piece, which can effectively block the crucible flange 4 from directly contacting the open flame and deforming. Moreover, the second isolation piece 2 is attached along the inner peripheral portion of the top of the furnace body panel 5 of the magnesium alloy furnace 3, and the second isolation piece 2 is a non-combustible heat insulation material piece, which can effectively block the furnace body panel 5 (which is a metal plate) from directly contacting the open flame and deforming. Moreover, since the contact surface of the first isolation piece 1 and the second isolation piece 2 is a conical surface, the two conical surfaces are in contact and compacted, which also helps to keep the furnace body panel 5 away from the open flame, reduce the deformation of the furnace body panel 5 (metal plate), and prolong the service life of the magnesium alloy furnace 3.

[0038] In summary, the magnesium alloy furnace mouth high-temperature sealing structure can solve the problems of magnesium alloy furnace 3, such as furnace mouth fire leakage, steel structure failure, and magnesium alloy furnace 3 shutdown maintenance, caused by the high-temperature flame in the furnace directly contacting the metal furnace body panel 5.

[0039] In one embodiment, as Figure 2As shown, the second isolation member 2 comprises a support steel plate 21 and a heat insulation member 22, the support steel plate 21 is vertically arranged between the bottom of the crucible flange 4 and the top of the furnace body panel 5, the support steel plate 21, the crucible flange 4, the furnace body panel 5 and the conical surface form a special-shaped cavity, and the heat insulation member 22 is cast in the special-shaped cavity. That is, the second isolation member 2 can be cast on the outside of the furnace body panel 5, so as to ensure that the second isolation member 2 fully wraps the metal furnace body panel 5.

[0040] In an embodiment, the cross section of the heat insulation member 22 comprises two symmetrically distributed acute angle cross sections, and the tips of the acute angle cross sections are oppositely distributed, so that the contact surface of the first isolation member 1 and the second isolation member 2 is a conical surface, and the furnace body panel 5 is further away from the open fire in the magnesium alloy furnace 3.

[0041] In an embodiment, the heat insulation member 22 comprises ceramic fiber castable.

[0042] It should be noted that the heat insulation member 22 of the industrial heat treatment furnace is a key component for ensuring the efficient operation of the furnace body, which not only affects the thermal efficiency of the furnace, but also relates to energy consumption and maintenance cost. Among them, the ceramic fiber castable is prepared by using high-quality low-slag ball content of sprayed ceramic fiber cotton as aggregate, adding various fillers, binders, additives and other materials, which has excellent properties such as temperature resistance, heat insulation, light weight and thermal shock resistance, and can effectively control the heat loss of the furnace body.

[0043] Of course, the heat insulation member 22 can also be made of diatomite heat insulation material, nano heat insulation plate or other heat insulation materials. The diatomite heat insulation material includes diatomite powder, diatomite brick, diatomite baked plate and diatomite asbestos powder, which is suitable for high temperature environment and has good heat insulation performance. The nano heat insulation plate has extremely low thermal conductivity, and its heat insulation performance is 4-6 times that of traditional heat insulation materials, which can effectively save energy, and the nano heat insulation plate is especially suitable for high temperature furnace wall, which can not only increase the space in the furnace, but also significantly reduce energy consumption. Other heat insulation materials include asbestos products, slag wool products, rock wool products, hard silicate stone type calcium silicate plate, vermiculite products, cement light aggregate castable, water glass light aggregate castable or expanded perlite.

[0044] In actual application, the material of the heat insulation member 22 can be determined according to actual conditions and actual needs.

[0045] In an embodiment, the first isolation member 1 comprises a ceramic fiber block, that is, the crucible flange 4 can be wrapped with the ceramic fiber block to avoid deformation caused by direct contact with open fire.

[0046] In an embodiment, a ceramic fiber blanket 6 is further included and is arranged between the first isolation member 1 and the crucible flange 4 to further wrap the crucible flange 4 with the ceramic fiber blanket 6 to avoid direct contact of the crucible flange 4 with the open flame.

[0047] In addition to the above-mentioned magnesium alloy furnace mouth high-temperature sealing structure, the utility model also provides a furnace body structure comprising the magnesium alloy furnace mouth high-temperature sealing structure disclosed in the above-mentioned embodiment, wherein the furnace body structure further comprises a furnace body, the first isolation member 1 of the magnesium alloy furnace mouth high-temperature sealing structure is wrapped around the outer peripheral portion of the bottom end of the crucible flange 4 of the furnace body, and the second isolation member 2 is attached along the inner peripheral portion of the top of the furnace body panel 5 of the furnace body. The structures of other parts of the furnace body structure refer to the prior art, and will not be described here.

[0048] In an embodiment, a heating burner 7 is further arranged on one side of the furnace body.

[0049] It should be noted that the core improvement of the magnesium alloy furnace mouth high-temperature sealing structure is mainly to add a fireproof heat insulation material between the magnesium alloy furnace body panel and the open flame. These fireproof heat insulation materials have the characteristics of high temperature resistance and can effectively isolate the open flame and reduce the direct heat effect of the high-temperature open flame on the furnace body panel 5, thereby prolonging the service life of the furnace body panel 5. In addition, the furnace body design of the magnesium alloy furnace 3 can also be improved to reduce the influence of the high-temperature open flame on the furnace body panel 5. For example, a heat insulation layer can be added or a double-layer structure can be used to reduce the direct conduction of heat, which not only protects the furnace body panel 5 but also improves the thermal efficiency of the entire furnace body.

[0050] It should be noted that the first isolation member 1 and the second isolation member 2 mentioned in the present application are only for distinguishing the different positions and have no sequence.

[0051] In addition, it should be noted that the "inside and outside", "top and bottom" and other indications of the orientation or position relationship in the present application are based on the orientation or position relationship shown in the drawings and are only for the convenience of simplifying the description and understanding, and therefore cannot be understood as a limitation on the utility model.

The same or similar parts of each embodiment can be referred to each other. Any combination of all the embodiments provided by the utility model is within the protection scope of the utility model, and will not be described here.
