引除去することを目的とする。As described above, in the slag removal operation, an operator stands on the side of a ladle or crucible which is a high heat source, mixes a descaling agent into the ladle or crucible, and removes the slag. Since the work to scoop up the slag floating in response to the descaling agent is performed, the removal work takes time and is very dangerous. In addition, the descaling operation is frequent and the working conditions are severe and poor. Furthermore, when adding additives such as descaling agents to the molten metal,
Since a large amount of dust is generated, and a worker performs slag removal work in the dust, there is a problem that the working environment is extremely poor. SUMMARY OF THE INVENTION It is an object of the present invention to suction and remove the noro floating on the surface of a molten metal using negative pressure by utilizing a specific gravity difference between the molten metal and the noro.

上げることはない。Next, the operation of the present embodiment will be described. The temperature of the molten metal 18 accommodated in the ladle 13 is about 1250 to 1500 degrees for cast iron and about 1000 to 120 degrees for copper alloy.
Although the temperature differs depending on the type of the molten metal, such as 0 degree or about 750-800 degrees for an aluminum alloy, all are high temperatures. Further, the suction force of the negative pressure generator 51 depends on the type of molten metal, such as cast iron, copper alloy, and aluminum. Adjust the negative pressure of the pressure generator for use. Cast iron has a specific gravity of about 7.1, so negative pressure is -20m
When set to mHg, the noro 19 and dust 20
8 can be separated and sucked, and the molten metal 18 is not sucked up.

ある。For example, in order to remove the slag 19 floating on the surface of the molten metal 18 made of pig iron, the negative pressure generator 51 is driven with the negative pressure adjusted to -20 mmHg, and then shown in FIG. As described above, when the suction port 25 attached to the tip of the suction tube 21 is inserted into the slag 19 in the ladle 13, only the slag 19 having a lower specific gravity than the molten metal 18 is generated by the negative pressure of the negative pressure generator 51. Is separated from the molten metal 18 and the suction port 2
5 is sucked into the suction tube 21 from the tip opening 26 of the suction tube 5.

きるため作業能率は一段と向上する。In this case, even if the suction port 25 is immersed in the molten metal 18, the noro 19 can be sequentially sucked from the notch 27. In this case, if the notch 27 is not provided, unless the bottom surface of the suction port 25 is positioned just below the surface of the molten metal, only air can be sucked and slag cannot be sucked efficiently. However, in this embodiment, if the tip opening 26 of the suction port provided with the notch 27 is immersed in the molten metal 18,
The excess opening is closed by the molten metal 18, so that the slag 19 can be efficiently sucked without sucking only the air. In this case, the work efficiency can be further improved because the cutout 27 can be replaced with one or two or four cutouts 27 as required.

Then, when it advances on the extension of the attachment opening 52 and collides with the shielding plate 55 located in front of the attachment opening 52, the flap 19 a falls down due to its repulsion or its own weight and is stored in the storage container 59. In this case, the shielding plate is about 4
If it is mounted at an angle of about 5 degrees, the slag piece 19a effectively descends after colliding with the shielding plate.

できる。The high heat resistance of the suction tube 21 and the heat-resistant hose 40 is about 300 to 400 because the noro 19 is air-cooled by the wind sucked by the negative pressure of the negative pressure generator 51.
It is enough if it can withstand high heat. In this case, if necessary, the second suction port 30 having a different tip shape can be used, or the third suction port 35 can be used to suck the stick. As described above, when the tip opening 56 is formed in an elliptical shape or an oval shape and the openings are formed to have different diameters, the suction opening can be rotated even in a portion having a different angle in the ladle. The tip opening can be brought into contact with the corner of the ladle to suck the slag.

Since the notch portion is provided at the opening at the tip, the stick 19 stuck to the refractory material inside the ladle 13 can be removed and sucked from the opening at the tip or the notch at the suction port. As described above, since no filtering rod or the like other than the suction cylinder 21 is required, the operator can easily perform the slag removing operation under dangerous high temperature.

Since no work is required, the workability of the slag removal work can be improved, the work time can be shortened, and the cost can be reduced.

A cover 16 is placed over the opening 14 of the ladle 13 to prevent white smoke and dust 20 generated by chemical change with an additive such as magfosium from rising into the factory. Next, a suction port 25 attached to the tip of the suction cylinder 21.
Is inserted into the ladle 13 from the tap hole 15 to perform the graphite spheroidizing process, thereby absorbing the white smoke and dust generated by the suction tube 21 to prevent the working environment in the factory from deteriorating. After the operation of absorbing and removing the white smoke and dust 20 is completed, the noro 19 floating on the molten metal is absorbed and removed using the suction port 27.

とができる。When the slag removal operation in the ladle 13 is performed in the factory, the heat-resistant hose 40 can be moved in the factory by making the heat-resistant hose 40 long and widening the movement range. In addition, the heat-resistant hose 40 may be suspended by a balancer (not shown) or the like, if necessary, at an intermediate portion of the heat-resistant hose 40.
The slag removal operation can be easily performed while reducing the weight burden on the slag.

者の健康を安全を確保することが出来る。According to the present invention, by utilizing the specific gravity difference between the molten metal and the noro, the noro floating on the surface of the molten metal can be separated and sucked at the suction port by the negative pressure generated by the negative pressure generator. In addition, the slag adhered to the inner surface of the ladle is also cut off by the notch provided in the suction port, so that the slag can be efficiently removed. Furthermore, white smoke and dust generated when additives are added in various processing steps such as graphite spheroidizing processing can be absorbed and removed using the negative pressure. Can ensure the health of the elderly.
