[0048] In this embodiment, the upper surface of the upper furnace door 4 is additionally provided with a first installation groove 401 and a second installation groove 402 for installing the first heat insulation layer 5 and the second heat insulation layer 6. This design greatly enhances the heat insulation effect of the upper furnace door 4 and reduces heat leakage during operation. When the first heat insulation layer 5 needs to be replaced, the equipment is first shut down, the residual materials inside the equipment are emptied, and after the equipment is cooled down, the first heat insulation layer 5 is lifted out of the first installation groove 401 by a crane for replacement; when the second heat insulation layer 6 needs to be replaced, it does not need to be shut down, and it can be directly lifted out by a crane for replacement.
[0049] Furthermore, the upper furnace door 4 also has a side opening 403, which is connected to the second mounting groove 402, and also includes a rotating rod 7. There are several rotating rods 7, one end of the rotating rod 7 is rotatably set on both sides of the upper furnace door 4; the other end of the rotating rod 7 is rotatably set on both sides of the cover plate 8, and after the rotating rod 7 is rotated, the cover plate 8 abuts against the side opening 403.

A rotating rod 7 and a cover plate 8 are also provided. Specifically, when the second thermal insulation layer 6 needs to be replaced, the rotating rod 7 is rotated to drive the cover plate 8 to move, thereby facilitating the replacement of the second thermal insulation layer 6. The advantage is that after adding this design, when the second thermal insulation layer 6 needs to be replaced, it is only necessary to rotate the rotating rod 7 to open the cover plate 8 without using a crane, thus saving manpower and material resources.
[0051] Furthermore, it also includes a fastener 9, which includes a first mounting frame 901, one end of which is arranged on the upper surface of the upper furnace door 4; a gear 902 is rotatably arranged on the other end of the first mounting frame 901; a movable plate 903 has a rectangular through groove 9031 in the middle, and a semicircular through groove 9032 is provided at one end of the movable plate 903, the rectangular through groove 9031 is connected to the semicircular through groove 9032, and the side walls of the rectangular through groove 9031 and the semicircular through groove 9032 are both provided with a number of evenly distributed internal teeth 9033, and the internal teeth 9033 are meshed with the gear 902; an abutment plate 904 is arranged at the other end of the movable plate 903 for abutting against the cover plate 8; a first abutment wheel 905 is used in pairs, and the first abutment wheel 905 is rotatably arranged on the upper surface of the upper furnace door 4, located below the movable plate 903, and is used to abut against the movable plate 903 to change the moving direction of the movable plate 903.
[0052] In this embodiment, a fastener 9 is additionally provided, and the fastener 9 includes a first mounting frame 901, a gear 902, a movable plate 903, an abutment plate 904 and a first abutment wheel 905. Specifically, the movable plate 903 is initially in a vertical state, and the gear 902 mounted on the first mounting frame 901 is initially engaged with the inner teeth 9033 at the semicircular through groove 9032. When the cover plate 8 abuts against the side opening 403, the gear 902 rotates to drive the movable plate 903 to move downward. When the movable plate 903 abuts against the first abutment wheel 905, the movable plate 903 will rotate in the direction of rotation of the gear 902. When the movable plate 903 rotates to a horizontal state, the movable plate 903 will move laterally under the rotation of the gear 902, so that the abutment plate 904 is close to the cover plate 8, thereby abutting the cover plate 8 more closely against the side opening 403.
[0053] Furthermore, there are two fasteners 9 disposed on both sides of the upper surface of the upper furnace door 4 , and also include a connecting rod 10 , both ends of which are respectively disposed on the two movable plates 903 .

[0056] In this embodiment, a second abutment wheel 906 and a third abutment wheel 907 are additionally provided. The advantage is that when the movable plate 903 moves laterally, it can abut against the second abutment wheel 906 and the third abutment wheel 907, thereby enhancing the stability of the structure and preventing damage to the equipment during operation.
[0057] Furthermore, it also includes a first lifting lug 11 , which is arranged on the upper surface of the first heat insulation layer 5 ; and a second lifting lug 12 is arranged on both sides of the upper furnace door 4 .
[0058] In this embodiment, a first lifting lug 11 and a second lifting lug 12 are additionally provided, which has the advantage that the upper furnace door 4 can be opened and closed and the first heat insulating layer 5 can be replaced more quickly and conveniently.
[0059] Furthermore, the second thermal insulation layer 6 is of split type, and has a plurality of mounting holes 601 . The second mounting groove 402 has a plurality of mounting posts 4021 . The second thermal insulation layer 6 is arranged on the mounting posts 4021 through the mounting holes 601 .
