[0028] The above are only preferred embodiments of the present invention, and are not intended to limit the implementation and protection scope of the present invention.
[0029] The present invention also has the following implementation modes based on the above:
[0030] In further embodiments of the present invention, please continue to refer to Figure 1 and Figure 2 As shown, a fourth arch brick group 14, a third arch brick group 13, a second arch brick group 12, a first arch brick group 11, another second arch brick group 12, another third arch brick group 13 and another fourth arch brick group 14 are arranged along the arch span direction.
[0031] In a further embodiment of the present invention, two second arch brick groups 12 are symmetrically arranged on the first arch brick group 11, two third arch brick groups 13 are symmetrically arranged on the first arch brick group 11, and two fourth arch brick groups 14 are symmetrically arranged on the first arch brick group 11.
[0032] In a further embodiment of the present invention, the first arch brick group 11 , the second arch brick group 12 , and the third arch brick group 13 are made of the same material.
[0033] In a further embodiment of the present invention, the material of the fourth arch brick group 14 is different from the material of the first arch brick group 11 .
[0034] In a further embodiment of the present invention, the first arch brick group 11, the second arch brick group 12, and the third arch brick group 13 are made of main brick material.
[0035] In a further embodiment of the present invention, the material of the fourth brick group is fused corundum brick or fused AZS brick or zircon brick or calcium-free silica brick.
[0036] The materials of the first arch brick group 11, the second arch brick group 12 and the third arch brick group 13 are main brick materials, mainly considering good high temperature performance, strong corrosion resistance, low density and low cost, such as silica bricks; the fourth arch brick group 14 is used in the area where the edge of the arch body is subjected to large stress, mainly considering good high temperature performance, strong corrosion resistance and high strength, such as fused corundum bricks, fused AZS bricks, zircon bricks, calcium-free silica bricks, etc.
[0037] In a further embodiment of the present invention, each arch body 1 is arranged in an arch shape.

[0040] In a further embodiment of the present invention, a first expansion joint 31 is formed between the first arch brick groups 11 of the two arch bodies 1, a second expansion joint 32 is formed between the second arch brick groups 12 of the two arch bodies 1, a third expansion joint 33 is formed between the third arch brick groups 13 of the two arch bodies 1, and a fourth expansion joint 34 is formed between the fourth arch brick groups 14 of the two arch bodies 1.

[0041] Since the materials of the first arch brick group 11, the second arch brick group 12, the third arch brick group 13 and the fourth arch brick group 14 are different, the sizes of the large arch concentrated expansion joints are different. The sizes of the expansion joints are set according to the expansion amount of the arch brick material. The distance of the first expansion joint 31, the distance of the second expansion joint 32, and the distance of the third expansion joint 33 are equal, and the distance of the first expansion joint 31 is greater than the distance of the fourth expansion joint 34.
[0042] The large arch of the melting furnace of the present invention is equipped with arch bricks of different thicknesses according to the different forces on various parts of the arch body 1. The force on the arch bricks gradually decreases from the edge to the middle of the arch body 1, and the thickness of the arch bricks is gradually thinned as needed. Compared with the traditional large arch with the same arch brick thickness in the entire arch body 1, the weight of the arch body is reduced, thereby reducing the force on the arch bricks, providing space for further increasing the arch span. This structure can also reduce the amount of bricks used and save costs.
[0043] The present invention adopts bricks with higher strength and better performance in the area of the edge of the arch body 1 where the force is greatest, thereby solving the risk problem of the main bricks of the large arch due to insufficient strength, and the arch span can be increased as needed.
