When the steel billet fixing device of the steel slag hot stewing pit is used, the clamping groove part 1 can be pre-embedded on the concrete side wall of the steel slag hot stewing pit 200, then the clamping part 2 connected with the steel billet 203 slides into the clamping groove part 1 along the height direction of the steel slag hot stewing pit 200, so that the steel billet 203 can be fixed on the inner side wall of the steel slag hot stewing pit 200, and at the moment, the bottommost part of the steel billet 203 fixedly connected with the clamping part 2 is directly abutted against the bottom wall of the steel slag hot stewing pit 200. The steel billet fixing device of the steel slag hot stewing pit enables the operation of the steel billet 203 to be simpler during the installation or the disassembly, and only the clamping piece 2 needs to slide into or move out of the clamping groove piece 1 along the height direction of the steel slag hot stewing pit 200, so that the installation and maintenance time of the steel billet 203 is reduced, and the labor intensity of workers is greatly reduced; in addition, the fastener 2 can only move up and down in the height direction of the steel slag hot stewing pit 200 in the fastener 1 in the process of matching with the fastener 1, and the freedom of movement in other directions is limited, so that the steel billet 203 can freely stretch and contract in the vertical direction, the problem of deformation caused by thermal expansion of the steel billet 203 is solved, and the service life of the steel billet 203 is prolonged; in addition, because the draw-in groove spare 1 can be pre-buried on the concrete lateral wall through pre-buried mode, draw-in groove spare 1 is as an organic whole with the concrete lateral wall is connected promptly at concrete placement in-process promptly, this kind of mode makes the junction of draw-in groove spare 1 and concrete lateral wall not have the installation hole, consequently its leakproofness is better, has solved and has adopted bolt and nut to install because of having the problem such as the gas leakage of steel slag heat braising hole 200 that the installation hole arouses among the prior art, scurries to help improving the treatment effeciency of steel slag.
According to the present invention, the chute member 1 may comprise a back plate 11 fixed to an inner sidewall of the steel slag hot-braising pit 200 and a stopper arm plate 12 connected to opposite sides of the back plate 11. A limiting space 13 for sliding in and out the fastener 2 is formed between the two limiting arm plates 12 and the back plate 11. It should be noted that the structure of the limiting arm plate 12 may be various, as long as it can satisfy the requirement of limiting the motion function of the fastener 2 in the height direction of the steel slag hot-stewing pit 200.
Specifically, in the preferred embodiment shown in fig. 1 and 2, each of the position-limiting arm plates 12 may include a vertical plate 121 vertically extending from one side of the back plate 11, and a horizontal plate 122 horizontally extending along a free end of the vertical plate 121, and the fastener 2 may include a connecting member 21 for fixedly connecting with the billet 203 and a stopper plate 22 vertically connected with the connecting member 21. The stop plates 22 are used for sliding into and out of the limit space 13, the horizontal plates 122 of the two limit arm plates 12 extend towards each other, and a distance D for passing through the connecting piece 21 is formed between the two horizontal plates 122. As shown in fig. 3, in this embodiment, the stopper plate 22 located in the limiting space 13 is restricted in displacement in the left-right direction by the two vertical plates 121 and in displacement in the front-rear direction by the two horizontal plates 122, and the distance D allows the passage of the link 21, so that the grommet 2 can move only in the up-down direction along the grommet 1.

In addition, the steel billet fixing device of the steel slag hot stewing pit enables the operation of the steel billet 203 to be simpler during the installation or the disassembly, and the buckling piece 2 only needs to slide into or move out of the clamping groove piece 1 along the height direction of the steel slag hot stewing pit 200, so that the installation and maintenance time of the steel billet 203 is reduced, and the labor intensity of workers is greatly reduced; in addition, the steel billet fixing device of the steel slag hot stewing pit also enables the steel billet 203 to freely stretch and contract in the vertical direction, solves the problem of deformation caused by thermal expansion of the steel billet 203, and is beneficial to prolonging the service life of the steel billet 203.
Preferably, in order to further improve the fixing strength of the slot member 1 and the concrete layer 201, the back plate 11 of the slot member 1 and the anchor bars 15 connected to the back plate 11 may be embedded in the concrete layer 201.
It is also preferred that temporary suspension points (not shown) be welded to billet 203 to facilitate installation of billet 203. During installation, a workshop crane can be used for vertically hoisting the steel billet, the lifting hook slowly descends, meanwhile, the clamping piece 2 slides into the clamping groove piece 1 through manual auxiliary alignment until the steel billet 201 reaches the steel slag hot stewing pit 200, and all the steel billets 203 are sequentially installed according to the method.
Further, after all the steel billets 203 are installed, a heat insulation layer 202 can be filled between the concrete layer 201 and the steel billet layer, and thus the installation of the steel slag hot-stewing pit 200 is completed.
