[0024] Embodiment 1

[0025] As Figure 1 shown;

[0026] A high-temperature iron runner structure includes an iron runner main body 1;

[0027] In this implementation: After checking, the publication (announcement) number: CN209065938U discloses a blast furnace iron runner. To solve the technical problems existing in this prior art, as disclosed in the background art above, "the impact area near the iron drop point of the main runner is frequently eroded by molten iron, and the movement trajectory of molten iron in the impact area is extremely complex, with the most serious erosion. It is the weakest link of the main runner and requires frequent shutdown repairs, which is very time-consuming for construction." In combination, this problem is obviously a real and difficult problem to solve. In view of this, to solve this technical problem, a buffer component 2 and a positioning component 3 are added on this basis.

[0028] Furthermore:

[0029] As Figures 1 to 4 shown;

[0030] Combined with the above content:

[0031] To reduce the erosion of molten iron on the main runner, this high-temperature iron runner structure further includes a buffer component 2 arranged on the surface of the iron runner main body 1;

[0032] The buffer component 2 includes a diversion block 22 arranged inside the iron runner main body 1. A fixing groove is formed inside the iron runner main body 1, and a second positioning block 24 is arranged inside the fixing groove. The second positioning block 24 is fixedly connected to the diversion block 22.

[0033] In this implementation: When molten iron is poured into the inside of the iron runner main body 1, the molten iron will hit the surface of the diversion block 22, and the diversion block 22 will buffer and divert the molten iron, thereby reducing the erosion of molten iron on the main runner.

[0034] Even further:

[0035] In an optional embodiment, the diversion block 22 is inclined in the direction of the molten iron flow.

[0036] In this embodiment: The flow dividing block 22 is inclined in the direction of the molten iron flow, facilitating the flow of the molten iron and preventing the molten iron from accumulating.

[0037] Furthermore:

[0038] In an alternative embodiment, a fixing ring 21 is provided on the surface of the molten iron groove main body 1. Two first positioning blocks 23 are symmetrically and fixedly connected to one side of the fixing ring 21 facing the molten iron groove main body 1. Two positioning grooves are symmetrically formed inside the molten iron groove main body 1, and the two first positioning blocks 23 are respectively inserted into the corresponding positioning grooves.

[0039] In this embodiment: When the molten iron is poured into the molten iron groove main body 1, the fixing ring 21 will concentrate the molten iron above the flow dividing block 22, preventing the molten iron from falling outside the range of the flow dividing block 22.

[0040] Furthermore:

[0041] In an alternative embodiment, a positioning assembly 3 is further included and is provided on the surface of the fixing ring 21;

[0042] The positioning assembly 3 includes four fixing frames 31 symmetrically and fixedly connected to the surface of the fixing ring 21. A slider 32 is provided inside each fixing frame 31, and the slider 32 is slidably connected to the fixing frame 31. A spring 34 is provided inside each fixing frame 31, and the two ends of the spring 34 are respectively fixedly connected to the fixing frame 31 and the slider 32. A rotating shaft 33 is rotatably connected to the inside of the two sliders 32 on the same side through a bearing. A connecting plate 35 is fixedly connected to the surface of the rotating shaft 33. A first limiting block 36 is fixedly connected to one side of the connecting plate 35 facing the molten iron groove main body 1. Two second limiting blocks 37 are symmetrically and fixedly connected to the surface of the molten iron groove main body 1.

[0043] In this embodiment: When it is necessary to position the fixing ring 21, insert the first positioning block 23 into the positioning groove, then apply force to the connecting plate 35 to make the connecting plate 35 rotate through the rotating shaft 33, and then pull the connecting plate 35. The spring 34 will be compressed, enabling the second limiting block 37 to limit the first limiting block 36, thus realizing the fixing of the fixing ring 21.

[0044] The working principle and usage process of the present utility model are as follows: When molten iron is poured into the interior of the main body 1 of the molten iron trench, the molten iron will strike the surface of the diversion block 22. The diversion block 22 will buffer and divert the molten iron, thereby reducing the erosion of the main trench by the molten iron. The diversion block 22 is inclined in the direction of the flow of the molten iron, facilitating the flow of the molten iron and preventing the accumulation of molten iron. When the molten iron is poured into the interior of the main body 1 of the molten iron trench, the fixing ring 21 will concentrate the molten iron above the diversion block 22, preventing the molten iron from falling outside the range of the diversion block 22. When it is necessary to position the fixing ring 21, insert the first positioning block 23 into the interior of the positioning groove, then apply force to the connecting plate 35 to make the connecting plate 35 rotate through the rotating shaft 33, and then pull the connecting plate 35. The spring 34 will be compressed, enabling the second limiting block 37 to limit the first limiting block 36, thus achieving the fixation of the fixing ring 21.

[0045] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
