いるのが現状である。In the conventional method for processing steel slag containing metal and slag (hereinafter referred to as steel slag) generated in the process of refining molten metal, the working path becomes longer and the steel slag that has been solidified and hardened using a high-pressure trowel is difficult to handle. It digs deeply into the ground, and its thickness is not uniform, making it difficult to peel it off after solidification, requiring a variety of heavy machinery and a large number of personnel, and it is also necessary to secure a work route for the discharge and deployment process. Ru. In addition, a large amount of dust was generated during the work, causing a pollution problem. Also, JP-A-5
Publication No. 0-454104 or JP-A-52-1368
The treatment method described in Publication No. 98 is a method in which the molten slag discharged from the refining process is discharged in a spread pattern over the entire area on the glass metal, and then forced cooling is performed by sprinkling water.
The molten slag in the molten state discharged in the refining process is 10
% of the molten metal, and if a forced cooling method is adopted in which the molten metal is simultaneously discharged into an expanded form and cooled water is poured in after sprinkling water, it is possible to remove the expanded solidified metal and ,
Due to the risk of steam explosion inside the boiler, molten metal with a high specific gravity must be left in the slag pan, cooled and solidified, and then treated separately, which causes many problems in actual work. What remains is the current situation.

Steel slag powder is spread as a floor covering in advance to improve removability. In addition, 1g of residue (semi-molten, solidified large lump slag or large metal) that is thicker than the lattice mesh will cause vibration of the lattice.
All of it is thrown into the pressurized container (3) by tilting. Here, adhesion of semi-molten slag to the grid is prevented by vibration of the grid. The frequency and inclination angle of the lattice described here are
A required value may be selected depending on the properties of the steel slag. Incidentally, the adhering slag in the waste container (l!9) is removed by the adhering slag removing device (50) provided in the bare metal adhering slag carrying out and removing device (5) and is discharged onto the vibrating grating flll.Adhering slag removal Device (5

The crushed steel slag passes through the sieve and falls onto the horizontal section (4I) of the conveying conoveyor (4) installed at the bottom, where it is conveyed to the left in the figure. The vertical packet conoveer (40) is discharged from the container (4) as floor covering into the connected metal container (2). Also, the large metal (' f - molten, solidified state) is compressed by the movable wall (□) and remains on the sieve. is compressed and transported from the other direction.

能ならしめるものである。As mentioned above, through the series of connecting operations of the devices (1) to (5), it is possible to easily separate the slag and metal in the steel slag during slag discharge, which was difficult with conventional methods. It is a processing method and device that minimizes the generation of dust by eliminating the need for various types of heavy machinery processing as in the past, and also allows for batch processing control, allowing the number of working personnel to be reduced to a maximum of 1x. In addition, in the conventional method, the large metal recovered from the steel slag is transported outside the processing plant, where it is divided and used as an iron source, but in this example, the pressurized container ( 3) The compressed metal remaining inside is removed using the tongs device (5) of the metal adhering slag removal device (5).
Since it is compressed again, it is not necessary to divide the large metal outside the processing plant as in the conventional method, and it is possible to directly transport the iron source to the site where it will be used.

工処理する。On the other hand, the steel slag discharged into the connected metal container (2) is continuously conveyed into the dust-proof cooling device (6),
The hood (64) is forcibly cooled to about 200'C to 300'C by water sprinkling from the internal water nozzle (61), but the cooling water is not injected into the cooling bit, and the spray type cooling method uses the required amount of cooling water. Therefore, there is no risk of steam explosion and it is safe.In addition, connected metal containers (2)
Since the shape of the metal is divided by a formula, it is easy to transport the metal after cooling and solidifying. Thereafter, after secondary magnetic separation and coarse crushing are performed by a secondary magnetic separator (7) and a coarse crusher (8), the iron is transported to an iron recovery crushing nibrant (9) using a required belt for processing.

工が可能である。(Effects of the Invention) As is clear from the above explanation, the steel slag processing method according to the present invention collectively performs the preliminary treatment of the separation of metal and slag and rough splitting at the stage of steel slag discharge. Because the equipment is configured to operate continuously, it is more efficient than conventional methods, and allows for centralized control that does not require a variety of heavy machinery or large numbers of personnel.
It is possible to save a lot of labor and to make the work route more compact. Also, since there is no need for heavy machinery to dispose of steel slag,
Dust is greatly reduced and the working environment is improved. In addition, since it is possible to process all the steel slag that is processed through molten metal, it is possible to process 90 degrees of continuous continuous processing.
construction is possible.
