[0004] This will be briefly described with reference to FIGS. 4 and 5. On the casting direction side of the mold 2 opened on the casting floor 1,
Dummy barker rails (not shown) are laid,
The dummy bar car 3 moves forward and backward on this car rail. A dummy bar 4 is mounted on the dummy barker 3, and a dummy bar guide member 5 is attached to the front end of the dummy barker 3 to serve as a guide when the dummy bar 4 is inserted into the mold 2.

In parallel with the dummy barker rail,
A rail 7 for a truck of a transport truck 6 for hardware is laid outside the outside. The carriage frame 8 of the carrier 6 is formed in a U-shape in plan view and extends forward (refers to the forward direction of the carrier 6; the same applies hereinafter). At the front end of the bogie frame 8, a mounting base 9 is fixed in the vertical direction. The mounting base 9 is provided with a pair of fingers 1 via a cross-shaped slide member 10 that slides left and right and up and down.

The proposed hardware loading device 19 has the following unsolved problems. 1)
Since the truck rails 7 are provided outside the dummy barker rails, the space for the casting floor 1 is taken up, which is not particularly preferable for a multi-strand continuous casting facility, and a transport cart 6 which moves on the truck rails 7 is provided. Therefore, not only the equipment cost is increased, but 2) the cooling hardware 15 held on the transporting trolley 6 and the mold 2
Is shifted in both the moving direction of the carrier 6 and the direction perpendicular thereto, and when the cooling hardware 15 is inserted into the mold 2, the carrier 6 is moved. Has been hindered. 3) In particular, when the casting in the preceding process is completed and the tundish car is evacuated, the mold is left as it is, and the next charge casting is performed. It takes a long time to prepare for charge casting, which hinders an improvement in the operation rate of the continuous casting facility.

[0010]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail with reference to the embodiments shown in the accompanying drawings. FIG. 1 is a side view of an embodiment of the present invention, FIG. 2 is an operation state diagram of FIG. 1, and FIG. 3 is a front view of FIG.

The present embodiment is an example of a cooling metal charging device in a continuous casting facility for slabs, and a cooling metal charging device 19a is directly and integrally attached to the front end of the dummy barker 3.

An outline of this embodiment will be described. In FIG.
An upper bracket 21 and a lower bracket 22 are attached to a front frame 20 supporting the dummy bar guide member 5 of the dummy barker 3. The upper and lower brackets 21 and 22 support the upper and lower ends of a pair of guide bars 23 (see FIG. 3). Also,
The lifting cylinder 13a is attached to the upper bracket 21.

A slider 24 is slidably fitted to the guide rod 23. A rod 25 of the lifting cylinder 13a is connected to the slider 24 via a pin coupling mechanism 26. Therefore, when the lifting / lowering cylinder 13a operates (expands or contracts), the slider 24
Is guided up and down by being guided by a guide rod (guide body) 23. A pair of fingers 11 and a pair of right and left metal pushing bars 16 are attached to the lower part of the front surface of the slider 24. A finger cylinder 14a is provided on the upper front surface of the slider 24. The rod of the finger cylinder 14a and one end of the finger 11 are connected via a toggle link 34, and the operation of the finger cylinder 14a ( The finger 11 is opened and closed by expansion and contraction.

Next, the components of this embodiment will be described in detail. The upper bracket 21 is roughly composed of a stand 27 erected on the front upper frame 20a of the dummy barker 3, a bracket 28 provided forward on the stand 27, and a rib 29 for supporting the bracket 28 from below. It is configured. The bracket 28 supports the upper end of the guide rod 23, and is provided with the elevating cylinder 13a, so that the rod 25 expands and contracts downward. Also, the lower bracket 2
2, the lower end of the guide rod 23 is supported.

The slider 24 is composed of a flat box 30, and the box 30 is slidably fitted to the pair of guide rods 23. A mounting plate 31 extending downward is provided on the front surface of the box 30. On the front surface of the mounting plate 31, the tip of the rod 25 of the lifting cylinder 13a is mounted on the upper portion thereof via a bracket by the pin coupling mechanism 26, and the finger cylinder is mounted on the center portion via the bracket. 14a is attached. Further, a pair of fingers 11 and a pair of metal pushing bars 16 are mounted on the lower side thereof.

The finger cylinder 14a is constituted by an air cylinder, and the lifting cylinder 13a
Is composed of a hydraulic cylinder. At the lower end of the finger 11, a pin 32 for cooling and inserting into a locking hole of the metal object 15 is projected outward so as to clamp (lock the metal object 15) when the lower ends are separated from each other. Therefore,
When these pins 32 are separated from each other, the cooling hardware 15 is clamped, and when they approach each other, they are unclamped. An intermediate portion of the finger 11 is rotatably supported by a pivot pin 33 projecting from the mounting plate 31. The upper end of the finger 11 has a toggle link 34,
It is connected to the rod 35 of the finger cylinder 14a via 34.

The metal pushing bar 16 is formed in an inverted T-shape, and is integrally fixed to both sides of an extension extending downward from the mounting plate 31. The upper surface of the cooling hardware 15 is pressed by the T-shaped horizontal portion 16a. The lower end of the metal pushing bar 16 is arranged above the position of the finger pin 32. The cooling hardware 15 is formed in an inverted torii gate shape, and the pin 32 of the finger 11 is inserted into its foot.

Next, the operation of this embodiment will be described. A case will be described in which after the casting in the previous step is completed and the tundish car has been retracted, the next charge casting is performed while leaving the mold 2 as it is.

The finger 11 is clamped in advance with a cooled metal 15 and the dummy barker 3 is advanced. When the cooling hardware 15 is positioned on the mold 2, the dummy barker 3
To stop. Therefore, when the lifting cylinder 13a is extended and operated, the cooling hardware 15 descends, and the cooling hardware 15 is lowered.
Is lowered to the position of the meniscus of the molten steel 18. Therefore, the cooling hardware 15 is in the resistance of the slab 17 and remains at the same position. However, the finger 11 and the metal pushing bar 16 are slightly lowered by the distance L shown in FIG.
Then, the elevating cylinder 13a is again extended and operated, and is cooled by the hardware pushing bar 16 to press the upper end surface of the hardware 15.

In this way, the cooling hardware 15 is pushed into the preset position by the lifting cylinder 13a and is held for several seconds. Thereafter, the finger 11 is closed (unclamped) by the operation of the finger cylinder 14a, and then the slider 24, that is, the finger 11 and the metal pushing bar 16 are raised by the contraction operation of the lifting cylinder 13a. As a result, mold 2
Since the molten steel 18 in the previous step in the process solidifies quickly, this final slab is pulled out. Next, when the dummy bar 4 is slightly advanced, the dummy bar 4 comes to a position where the dummy bar 4 can be inserted into the mold 2. Therefore, the dummy bar 4 is charged. Although the present embodiment has been described with reference to a cooling hardware, the present invention is not limited to this, and a joint hardware may be used.

[0023]

According to the present invention, since the hardware loading device including the hardware gripping finger and the hardware pushing bar is attached to the front frame of the dummy bar guide member of the dummy barker, the casting floor for the hardware loading device is provided. There is no need to provide space, and equipment costs can be reduced. Of course, the dummy bar guide member of the upper loading type is almost vertical, so the mounting of the lifting cylinder and guide is easy, and the number of shared parts is increased. And a compact and inexpensive construction, and reduce the distance between the dummy barker and the hardware loading device,
The forward / backward movement of the dummy barker can be slightly increased, so that the preparation time can be shortened and the positioning of the loading of hardware can be facilitated.

The left and right positions of the hardware held in the hardware loading device and the mold coincide in advance because the centering is performed by the dummy barker when the dummy bar is loaded.
In particular, it is not necessary to use a cylinder that operates in the horizontal direction as shown in Japanese Utility Model Laid-Open Publication No. 4-43448, and only the automatic adjustment in the front-rear direction by the dummy barker positioning and fixing device is required. That is, positioning can be performed quickly, that is, the preparation time is reduced.

Each of the operations of the end of the casting in the previous process, the loading of the cooling hardware, and the loading of the dummy bar can be continuously and rapidly performed, and in combination with the rapid positioning of the cooling hardware and the mold, In addition to shortening the time required for casting, it is possible to continuously load dummy bars from the upper loading dummy barker after cooling metal is put into the meniscus of the molten steel in the previous process. Thus, the operating rate of the continuous casting facility can be increased.

Since the slider is provided with a finger and a pair of right and left push bars, centering of the hardware and automatic positioning of the hardware on the push bar can be achieved. In particular, the hardware is inclined by the pair of right and left push bars. Since it can be pushed in without using it, proper metal loading can be performed in combination with the above-described positioning accuracy.

When a hardware loading device is to be attached to a tundish car, the tundish car mounts or unloads the tundish, and the tundish contains high-temperature molten steel. If the charging device and the tundish car are not provided and connected at a distance, heating will cause inconvenience in metal loading work and charging operation, and in particular, the cooling hardware at the angle will be heated. If the hardware loading device is attached to the dummy barker, there is no such heat problem, and both can be brought as close as possible, which can contribute to shortening the preparation time.
