Description
Technical Field
The utility model belongs to the technical field of electric furnace smelting, and particularly relates to an electric furnace masonry chute.
Background
In the electric furnace smelting process, slag iron can automatically realize slag iron separation in a molten pool of the electric furnace due to the difference of specific gravity of the slag iron, slag on the surface layer can enter a water quenching pool through a slag discharge port and a chute, and molten iron on the lower layer can enter an pig iron machine through a tap hole and the chute.
However, the chute adopted by the electric furnace at the current stage is generally a cast steel integral casting chute, and the chute has the defects of long processing and manufacturing period and high cost. In addition, when the special condition that the chute needs long distance laying, the installation and the disassembly of the chute are very inconvenient because of the heavy weight and long length of the chute.
Disclosure of utility model
Compared with the traditional cast steel integral casting chute, the electric furnace masonry chute provided by the utility model has the advantages that the processing and manufacturing period of the chute can be greatly shortened, the manufacturing cost of the chute can be greatly reduced in terms of raw materials, and the difficulty in mounting and dismounting the chute can be greatly reduced because the chute can be mounted in a prefabricated assembly mode.
In order to achieve the above purpose, the present utility model adopts the following technical scheme: an electric furnace masonry chute, the whole cross section of which is U-shaped, comprises a shell, ramming materials and pouring bricks; a layer of ramming mass is laid on the inner surface of the shell and used as a refractory material interlayer; the pouring type bricks are paved inside the shell, the pouring type bricks are separated from the inner surface of the shell by ramming materials, and ramming materials are filled in the spliced seams of the adjacent pouring type bricks.
The shell is an integral component formed by splicing and welding steel plates, and the size parameters of the shell are determined according to the iron slag conveying distance and the iron slag flow.
And a hanging ring is pre-buried and fixed at the top of the pouring type brick.
The utility model has the beneficial effects that:

Drawings
FIG. 1 is a schematic view of the construction of an electric furnace masonry chute of the present utility model (top view);
FIG. 2 is a cross-sectional view A-A of FIG. 1;
In the figure, 1-shell, 2-ramming mass, 3-pouring brick, 4-hanging ring and 5-splice joint.
Detailed Description
The utility model will now be described in further detail with reference to the drawings and to specific examples.
As shown in fig. 1 and 2, the overall cross section of the electric furnace masonry chute is U-shaped and comprises a shell 1, ramming mass 2 and pouring bricks 3; a layer of ramming mass 2 is paved on the inner surface of the shell 1, and the ramming mass 2 is used as a refractory material interlayer; the pouring type bricks 3 are paved inside the shell 1, the pouring type bricks 3 are separated from the inner surface of the shell 1 by ramming materials 2, and the splicing seams 5 of the adjacent pouring type bricks 3 are filled with ramming materials 2.
The shell 1 is an integral component formed by splicing and welding steel plates, and the size parameters of the shell 1 are determined according to the iron slag conveying distance and the iron slag flow.
And a hanging ring 4 is pre-buried and fixed at the top of the pouring type brick 3.
The following describes a one-time manufacturing and using process of the present utility model with reference to the accompanying drawings:
When the electric furnace masonry chute is required to be installed between the electric furnace slag outlet and the water quenching tank and between the electric furnace iron outlet and the pig iron machine, firstly, the length and the section size of the shell 1 are determined according to the iron slag conveying distance and the iron slag flow, and then the shell 1 is assembled and welded by steel plates according to the designed size until the shell 1 is manufactured.
After the shell 1 is manufactured, firstly, paving a layer of ramming material 2 with the thickness of 50mm on the inner surface of the shell 1, after the ramming material 2 is hardened into a refractory interlayer, hoisting prefabricated pouring bricks 3 into the U-shaped groove of the shell 1 one by one through hoisting rings 4, and filling the pouring bricks 3 by using the ramming material 2 in a splicing joint 5 until the pouring bricks 3 are completely paved, wherein the electric furnace masonry chute is also manufactured.
When the electric furnace is put into use, slag flowing out from the slag discharging port enters the water quenching tank through the electric furnace masonry type chute, and molten iron flowing out from the iron outlet enters the pig machine through the electric furnace masonry type chute.
When the iron slag flows through the electric furnace masonry type chute, the pouring type bricks 3 are blocked by the ramming materials 2 at the splice joint 5 and the outer surface, so that molten iron slag is prevented from directly contacting with the shell 1, and the shell 1 is prevented from being damaged by the molten iron slag.
The embodiments are not intended to limit the scope of the utility model, but rather are intended to cover all equivalent implementations or modifications that can be made without departing from the scope of the utility model.
