Description

The present invention relates to a jig.

Conventionally, methods have been proposed for recovering high-temperature molten materials such as steel slag.

For example, Patent Document 1 describes a method for recovering steelmaking slag, which is characterized by collecting molten steelmaking slag in a slag pan, cooling and solidifying it to a temperature of 140°C to 400°C, then turning the slag pan over and placing it on a slag recovery container that has been placed in a sealed room beforehand, thereby causing the steelmaking slag in the slag pan to fall into powder. This recovery method is described as having many advantages, such as allowing the slag to fall naturally in a sealed container, generating no dust, and allowing the slag to fall from the slag pan simply by being left there, eliminating the need for manual processing such as removing the slag from the slag pan as in the past, and because the steelmaking slag obtained does not require water spraying, it is dry and does not contain moisture, and can be reused as a slag-making material during steelmaking.

The present invention will be explained.
The present invention stores a high-temperature molten material inside, and after fishing it with a first hook connected to a first crane, uses a second hook connected to a second crane to hook the hanger having a vertical hole provided at the lower part of the side surface. A jig that can be attached to the hanger and hang the second hook in a metal pot that can discharge the high-temperature molten material from the inside when tilted by moving the pot upward, the jig comprising: a ring-shaped main body disposed so as to pass through the vertical hole that the hanger has; and a main body connected to the main body so that the main body does not hang down when the pot is fished up with a first hook; and a rod-shaped first stopper extending from the pot toward the side surface or bottom surface of the pot.
Such a jig is hereinafter also referred to as "the jig of the present invention".

The jig of the present invention is attached to a metal pot for storing a high-temperature molten material such as steel slag.
Here, the high-temperature molten material may be steel slag.
Furthermore, an example of such a metal pan is a slag pan for storing steel slag.

For example, a slag pan can be used to store steel slag, lift it up with a crane and move it, and then charge or discharge the steel slag into another storage tank, another device, or the like.
Here, a granulated slag manufacturing device is exemplified as another storage tank or another device. A granulated slag production device is a device that sprays water at high speed onto charged steel slag to granulate the steel slag. Other storage tanks and other devices include waste tanks.

The case where the high-temperature molten material is steel slag and the metal pot is a slag pan will be described below with reference to Figs. 1 to 7.
However, the jig of the present invention is not limited to these, and can be similarly applied to high-temperature molten materials other than steel slag and metal pots other than slag pans.

A conventional slag pan 10 has a hanging base 12 at the bottom of the side as shown in Fig. 1. The hanging base 12 may have a vertical hole _12X . Here, the vertical hole refers to a hole that penetrates in a substantially horizontal direction as shown in Fig. 1.
1, with the slag pan 10 placed on the floor 300, a second hook 210 connected to a second crane 200 is hung in the vertical hole _12X . The second hook 210 can be moved up and down by operating the second crane 200.
If a person were to hang the hook 210 in the vertical hole _12X , the person would be forced to approach the high-temperature slag pan 10, which would place a strain on the person.

Thereafter, with the steel slag 400 stored inside, the slag pan 10 is lifted up by the first hook 110 connected to the first crane 100 and moved to a desired location.
Then, when the second crane 200 is operated to move the hook 210 upward while the slag pan 10 is hooked up by the first hook 110 connected to the first crane 100, the slag pan 10 is tilted as shown in FIG. The steel slag 400 in the slag pan 10 can be discharged from the slag pan 10 to a desired device or the like.

The jig of the present invention is used by being attached to the vertical hole _12X formed in the hanging base 12 of such a slag pan 10.

The jig of the present invention will be described with reference to FIG.
FIG. 3 is a schematic perspective view illustrating the jig of the present invention.
The jig 1 of the present invention shown in FIG. 3 is attached to a vertical hole _12X provided in a hanging point 12 provided at the lower part of the side of a slag pan 10.
A second hook 210 can be hung on the jig 1 of the present invention, which can be moved up and down using a second crane 200.
Also in FIG. 3, slag pan 10 is placed on floor 300 .

The jig 1 of the present invention shown in FIG. 3 has a main body 3 and two first stoppers 5.

The main body part 3 is ring-shaped and is arranged so as to pass through a vertical hole _12X of a hanger 12 provided at the lower part of the side surface of the slug pan 10.

The main body 3 needs to be strong enough to withstand the operation of tilting the slag pan 10 by attaching the second hook 210 and lifting it with the second crane 200. Therefore, the main body 3 is preferably made of a metal, for example, and more preferably made of a steel material.

Although the main body portion 3 is ring-shaped, a portion of the ring may be missing. However, since a certain level of strength is required as mentioned above, it is preferable that the ring is not partially chipped.

The thickness of the ring of the main body 3 is not particularly limited, but since a certain level of strength is required as described above, it is preferable that the ring is thick. On the other hand, the ring must be thick enough to pass through the vertical hole _12X of the hanging base 12 provided at the bottom of the side of the slag pan 10.

The first stopper 5 of the jig 1 of the present invention is connected to the main body 3 and has a rod-like shape extending from the main body 3 toward the side or bottom of the slag pan 10 when placed on the floor 300 as shown in FIG. belongs to. As shown in FIG. 3, the first stopper 5 is preferably connected to the main body 3 at a portion of the main body 3 near the hanger 12.
The first stopper 5 is screwed to the main body 3, for example.
Although the first stopper 5 shown in FIG. 3 has a straight rod shape, it does not necessarily have to be straight.

If the jig 1 of the present invention does not have the first stopper 5, when the slag pan 10 is hooked up by the first hook 110, the main body 3 hangs down toward the floor 300, as shown in FIG. That is, the line connecting the point in contact with the hanging base 12 on the main body part 3 to the point farthest from the hanging base 12 hangs down so as to be substantially parallel to the vertical direction.
However, since the jig 1 of the present invention has the first stopper 5, when the slag pan 10 is hooked up by the first hook 110, the first stopper 5 comes into contact with the side or bottom surface of the slag pan 10, so that as shown in FIG. , the main body part 3 does not hang down.

There are no particular limitations on the material or size of the first stopper 5. It is preferably made of metal, and more preferably made of steel.

Moreover, the jig 1 of the present invention illustrated in FIG. 3 and FIG.
The second stopper 7 is rod-shaped and connected to the main body 3. As shown in Figures 3 and 5, the second stopper 7 is preferably connected to the main body 3 at a portion of the main body 3 away from the hanging point 12.
The second stopper 7 is fixed to the main body 3, for example, by a screw. In the embodiment shown in Fig. 3 and Fig. 5, the second stopper 7 is relatively rotatable about the point where it is fixed to the main body 3 by the screw. Therefore, as shown in Fig. 5, the second stopper 7 hangs down when it moves away from the floor 300. In other words, the second stopper 7 hangs down so that the line connecting the point where the second stopper 7 is connected to the main body 3 to the point farthest from the connection point is approximately parallel to the vertical direction.

Although the second stopper 7 shown in FIGS. 3 and 5 has a straight rod shape, it does not necessarily have to be straight.

As shown in FIG. 3, the second stopper 7 extends from the main body 3 to the floor 300 so that the first stopper 5 does not touch the side and bottom surfaces of the slag pan 10 when the slag pan 10 is placed on the floor 300. . Conversely, since the second stopper 7 extends from the main body 3 to the floor 300 and serves as a support to prevent the main body 3 from hanging down, as a result, the first stopper 7 5 does not touch the side and bottom surfaces of the slag pan 10.

The jig 1 of the present invention does not need to have the second stopper 7, but if the jig 1 of the present invention has the second stopper 7, when the slag pan 10 is placed on the floor 300, the jig 1 of the present invention may not have the second stopper 7. It is easy to hang the second hook 210 on the tool 1.

There are no particular limitations on the material or size of the second stopper 7. It is preferably made of metal, and more preferably made of steel.

As shown in FIG. 6, when the second hook 210 is hung on the jig 1 of the present invention and the second hook 210 is moved upward using the second crane 200 to tilt the slag pan 10, the first stopper 5 Preferably, no stress is applied from the side or bottom surface of the slag pan 10. This mainly depends on the angle formed between the main body part 3 and the first stopper 5. In other words, it is preferable that this angle is not too large. That is, the angle formed by the main body part 3 and the first stopper 5 is such that the second hook 210 is hung on the jig 1 of the present invention, the second hook 210 is moved upward using the second crane 200, and the slag pan 10 is Preferably, the angle is such that no stress is applied to the first stopper 5 from the side or bottom surface of the slag pan 10 when it is tilted.
When the second hook 210 is hung on the jig 1 of the present invention and the second hook 210 is moved upward using the second crane 200 to tilt the slag pan 10, the side or bottom of the slag pan 10 is attached to the first stopper 5. If there is no contact, such stress will not be applied.

Note that when the second hook 210 is hooked onto the jig 1 of the present invention and the second hook 210 is moved upward using the second crane 200 to tilt the slug pan 10, the main body 3 is tilted as shown in FIG. It faces approximately vertically. That is, in the main body part 3, a line connecting the point in contact with the hanging base 12 to the point farthest from the hanging base 12 in the main body part 3 faces in the vertical direction.

FIG. 7 is a schematic side view showing a state in which the jig 1 of the present invention, which is a preferred embodiment having the second stopper 7, is attached to the vertical hole _12X of the hanging base 12.
As shown in FIG. 7, when the slag pan 10 has a mortar shape, the hanging base 12 is located at a position that cannot be seen from directly above or is difficult to see. Therefore, conventionally, as shown in FIG. 1, there have been cases in which a person has to hook the hook 210 into the vertical hole _12X . In this case, the person would have to come close to the hot slag pan 10, which would put a strain on the person.
However, when the jig 1 of the present invention is attached to the vertical hole ₁₂ The hook 210 can be hung on the jig 1 of the present invention. Therefore, the burden that was traditionally imposed on people can be eliminated.

As shown in FIG. 7, the second stopper 7 supports the main body part 3 when the slag pan 10 is placed on the floor 300, and the second stopper 7 has a length that allows the second hook 210 to be hung on the jig 1 of the present invention. Preferably, it is the same.

The size of the jig 1 of the present invention is such that when a metal pot such as a slag pan is placed in another device, the jig 1 of the present invention attached to this does not interfere with other devices etc. Preferably, the pod shape is adjusted.
