BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ladle for casting.

[0002]

2. Description of the Related Art A conventional ladle is a ladle for storing molten metal in a ladle.
The upper part is a supply for receiving molten metal from the melting furnace
And a casting part for pouring into the mold in the radial direction
A supply wall and a casting part.
Formed at the lower part of the molten metal storage space
Was

[0003]

The present invention is, however, the slave
In the next ladle, the partition wall is vertical
Slag that floats in the supply section
As it is blocked by the partition wall, it may flow into the casting
Is formed in the supplied molten metal,
Slag may also float on the casting part side,
Pouring slag into the mold and deteriorating casting quality
There was a problem . Also, on the partition wall which is almost upright
Since the supplied molten metal collides with the wall, the partition wall is
There was also a problem that it was easily damaged. An object of the present invention, the above eliminates the conventional problems, is to provide an ladle possible to prevent the slag from flowing into the mold is accompanied to pouring.

[0004]

In order to achieve the above-mentioned object, the present invention provides a partition wall with its upper end placed flat.
Be separated from each other so that they are on the supply side with respect to the lower end.
Two sheets are placed one on top of the other
Place the cut wall on the upper end of the partition wall
Located above and below the surface of the molten metal
The upper end of the partition wall that has been
It is characterized in that it is positioned higher than the lower end , and its operation and effect are as follows.

[0005]

[Action] That is, according to the above configuration, when supplying the molten metal to the ladle from the melting furnace, the slag generated during the melt, because the specific gravity of the slag itself is small, the supply section by a partition wall
Floating above the melt while being guided to the side
Become floating inside the department . The molten metal supplied from the supply unit flows downward from the lower part while flowing into the casting part through the communicating part formed in the lower part of the molten metal storage space.
The molten metal that exceeds the placed partition wall is placed above
Also flows into the casting section through the gap between the
Floating due to the lower end of the partition wall placed above
Slag is prevented from flowing into the casting portion.
You. Further, the partition wall is moved from the supply section side to the casting section side.
The molten metal flows along the partition wall
Flow down, the partition wall is
Can be prevented from being damaged. On the other hand, the floating slag, except for the lower part of the molten metal accommodating space in the ladle, is radially partitioned by the partition wall into the supply section and the casting section, so that it cannot enter the casting section side, As a result, slag-free molten metal accumulates on the casting part side, and even if the ladle is tilted and pouring operation is performed, the partition wall prevents the inflow of floating slag to the casting part side, and the slag-free casting part remains. Can be poured into the mold. Only
Also prevent slag from entering the casting
Not only in the lower part of the accommodation space, but also
A communication part between the supply part and the casting part is also formed between them
Therefore, the molten metal from the supply section to the casting section during pouring
Can be easily distributed, increasing the pouring speed.
Wear.

[0006]

[Effect of the Invention] Therefore, it is possible to prevent the slag from flowing into the mold and to reduce the damage to the ladle, so that the casting cost can be reduced and the quality of the casting can be reduced . It has become possible to provide a ladle that can prevent deterioration.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 4 shows a centrifugal casting apparatus. This centrifugal casting apparatus includes a cylindrical mold 1, a roller R for rotating the mold 1 around an axis, and a pouring mechanism 3 for pouring molten metal into the mold 1.
And so on.

The pouring mechanism 3 is a pot-type ladle 4 for measuring and holding a predetermined amount of molten metal from a melting furnace 2 for storing molten metal.
A ladle 5 for pouring the molten metal into the mold 1 from the ladle 4, and a mounting table 6 on which the ladle 5 is mounted.

The ladle 4 is suspended from and supported by a monorail 7, and is reciprocated between the melting furnace 2 and the grove 5 by electric power. For the grinder 5, the pouring handle 8 is operated to incline the ladle 4 for pouring.

Hereinafter, the structure of the round pot 4 will be described in detail.

As shown in FIGS. 1 and 2, the round pan 4
A refractory partition wall 9 is provided on a steel vessel body 12, and the partition wall 9 is used to supply the upper part of the molten metal storage space in the ladle for receiving molten metal from the melting furnace 2. Part 10 and casting part 1 for pouring into the mold
1 and radially separated.

[0013] The partition wall 9 is positioned with respect to the main body 12.
Opposite to the tilting direction of the ladle over two stages in the radial direction
It is fitted and assembled in a state where it is inclined in the direction.Upper row
Cut wall 9AThe upper end is higher than the surface of the
Is also located above,Lower partition wall 9B
Is a certain distance between the lower end and the bottom of the container body 12.
Provided and attached to the vessel body 12. Lower partition wall 9
And the space between the bottom of the vessel body 12Partition walls 9
A, 9BWith the space between the supply unit 10 and the casting unit 11
And a communication portion 13 that communicates with.

FIG. 3 shows a state in which the ladle 4 having the above-described configuration is tilted and the molten metal is poured into the grinder 5. In the figure, reference numeral 14 denotes a floating slag generated on the supply unit 10 side. As shown in FIG. 3, the slag 14 is prevented from entering the casting portion 11 by the upper partition wall 9 </ b> A.
Only the molten metal in the casting part 11 flows.

In this case, since the partition wall 9 is attached to the vessel main body 12 in a state where the partition wall 9 is inclined in a direction opposite to the tilting direction of the ladle 4, when the ladle 4 is tilted, as shown in FIG. And the slag 14 is effectively prevented from entering the casting portion 11 side.

The partition wall 9 does not need to be provided over two upper and lower stages, but may be provided only on one stage or over three or more stages.

The partition wall 9 may be provided at a radially central portion of the vessel main body 12, or may be provided at a position shifted from the central portion.

In the claims of the utility model registration, reference numerals are written for convenience of comparison with the drawings, but the present invention is not limited to the configuration of the attached drawings by the entry.
