DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention automatically automates the work around a casting floor in a continuous casting facility, and in particular, automatically inserts powder for continuous casting and inserts an iron plate for separating molten steel during a continuous casting operation of different steel types. The present invention relates to an apparatus for automating a continuous casting operation that can be performed.

[0002]

2. Description of the Related Art A typical example of a conventional powder feeding machine and an iron plate inserting apparatus for separating molten steel is as follows. A powder storage tank is installed at the rear end of the traveling trolley, and the powder is sent with a flexible screw conveyor to the input chute that is pivotally attached to the front end of the traveling trolley,
Further, a method in which a charging chute provided with a pusher for extruding into the mold slides in contact with a guide parallel to the long side of the mold to charge the powder (Japanese Patent Publication No. 60-57937). It has a loading arm and a gripper for gripping an iron plate at its tip,
A method in which an iron plate is carried to a position above the mold, moved up and down to insert it into the mold, and laterally moved to weld the iron plate to the inner wall of the mold (Japanese Patent Publication No. 1-2611).
No. 8).

[0003]

However, these conventional examples have the following problems. Since the powder feeder and the molten steel separating iron plate insertion device each have a separate drive system, a large space is required when they are installed at the same time. When the path between the powder storage tank and the charging chute is long and non-linear, the conventional flexible screw conveyor breaks its outer wall and leaks powder, so that efficient powder transport cannot be performed. In the same continuous caster having two different types of molds (for slab and twin bloom), the shape of the iron plate to be inserted is different, and a single gripper having a fixed grip distance cannot be used.

[0004] The present invention has been made to solve the problems of these conventional powder injection machines and iron plate insertion devices.
It is an object of the present invention to provide an automatic casting and casting apparatus capable of automatically performing powder feeding in a continuous casting facility and inserting a separated iron plate during continuous casting of different types of steel.

[0005]

SUMMARY OF THE INVENTION The present invention is configured as follows to achieve the above object. That is, the present invention
A turning shaft is erected on a traveling vehicle, and a powder input device and an iron plate insertion device capable of turning independently around this axis are attached. The powder input device comprises a powder input arm and an input chute. Is composed of an iron plate insertion arm and a vertically movable gripper, and a powder introduction system for the powder introduction machine is composed of a sub-hopper and a telescopic intermediate chute separated from the powder introduction machine, and the powder is passed through the sub-hopper and the intermediate chute. An automatic casting and casting operation apparatus characterized in that the casting and dropping apparatus is configured to drop into a charging chute portion of a powder charging machine and to be extruded into a mold by a pusher.

[0006]

The powder input device and the molten steel separating iron plate insertion device can be installed in a narrow space around the continuous casting machine mold without interfering with other casting operations. In the case where the distance between the charging chutes from the powder storage tank is long, it is possible to supply the amount of powder for one charge into the mold variably and intermittently in the powder transportation. In addition, it becomes possible to separate the charging chute and the powder storage tank from a distance. Even when the shape of the iron plate to be inserted is different, the interval between the two grippers for gripping the iron plate fluctuates, so that the iron plate can be inserted.

[0007]

FIG. 1 is an overall view of an apparatus configuration illustrating the present invention, and FIGS. 2 and 3 are enlarged views of a main part of FIG. According to the present invention, as shown in FIGS. 1, 2, and 3, one turning shaft 4 is provided on a carriage 3 that can travel on the long side of the mold 1, and each turning shaft 4 is independently provided around the turning shaft. A pivotable iron plate insertion arm 5 and a powder input arm 8 are attached. When the powder input device 30 is operating and the iron plate insertion device 40 is on standby, as shown in FIG. When the iron plate insertion arm 5 is located farther from the mold, and the iron plate insertion device is operating and the powder injection machine is on standby, as shown in FIG. 3, the iron plate insertion arm 5 is on the mold side and the powder injection arm 8 is on the mold side. Located on the far side.

On the front surface of the iron plate insertion arm 5, an elevating unit 6 for inserting the iron plate into the mold and two grippers 7 for gripping the iron plate are installed, and a cylinder 24 arranged inside the elevating unit 6 as shown in FIG. As a result, the distance between the two grippers 7 varies. The injection chute 9 has a cylinder 2 for powder input.
A three-drive pusher 22 is provided, and the injection chute 9 has a structure capable of turning in the longitudinal direction of the mold 1 as indicated by an arrow 25 in FIG.

FIG. 1 shows a method for supplying powder to a powder chute. The surge hopper 16, the relay hopper 15, and the pressure feed pipe 14 are fixedly installed. The intermediate chute 10 is mounted on the mold 1 and the tundish car 2 traversing the short side. Does not interfere with the gripper 7 raised by the cylinder 21.

The intermediate valve 19 opens and the surge hopper 16
When the powder is supplied into the relay hopper 15, a fixed amount of powder is cut out from the relay hopper 15 by the pinch valve 17, and
4 and pneumatically fed to the input hopper 13. When a certain amount of powder fed into the charging hopper 13 is opened, the charging hopper 13 opens the cloth hose 1.
2. It falls into the input chute 9 via the sub hopper 11 and the intermediate chute 10 and is pushed out into the mold 1 by the pusher 22.

[0011]

According to the powder feeding and iron plate inserting / combining machine of the present invention, the following effects can be expected. In a continuous casting machine having two different types of molds (for example, for a slab and for a twin bloom), it is possible to automate a typical casting operation of charging powder and inserting a separate iron plate. Even in a limited narrow space, the above-mentioned equipment can be embodied due to a compact device configuration, and a typical casting operation of powder input and separation iron plate insertion can be automated.
