Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for mechanically attaching a sliding nozzle plate to a pouring portion of a storage container such as a tundish or a ladle.

[0002]

2. Description of the Related Art Conventionally, when a sliding nozzle (SN) plate having a plurality of fixed plates and sliding plates is attached to a storage container, the plate itself has a special shape that is not stable. Since it is necessary to make the surface pressures of the plates at the subsequent stages uniform, the constituent plates were manually placed one by one at the pouring port.

[0003]

This manual installation work is not only inefficient, but also requires severe work due to the narrow working environment.

However, even if this is simply mechanically conveyed and attached, there are many problems to be solved, such as the work of aligning the nozzle holes of the sliding plate and the fixed plate, application of surface pressure between the plates, and the like. is there.

An object of the present invention is to solve the problems in mechanical processing and to provide an operating system for mechanically and accurately attaching an SN plate to a storage container.

[0006]

SUMMARY OF THE INVENTION A sliding nozzle plate mounting system of the present invention comprises a plurality of sliding nozzle plates with their nozzle holes oriented in a particular direction.
Set the set cartridge placed in a specific position and the sliding nozzle plate placed in the set cartridge into one
The present invention is characterized in that it is composed of a transfer section that picks up each set and transfers it to a mounting station, and a mounting station that mounts the sliding nozzle plate that has been transferred to the station to the tap hole of the molten metal storage container.

[0007]

According to the present invention, a mechanical mounting system for a sliding nozzle plate is constituted by a set cartridge adapted to be picked up by mechanical means, a transport section for transporting by a simple operation, and a mounting station. It becomes easy to apply to full mechanical operation.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a diagram showing an arrangement of devices for mechanically attaching an SN plate set having a two-stage structure of a sliding nozzle plate and a fixed nozzle plate.

In the figure, A is a sliding nozzle plate a.
2 shows a set cartridge in which an SN plate set c having a two-stage structure of a fixed nozzle plate b and is arranged. B
Shows a transport unit that picks up the SN plate sets c one by one from the set cartridge A and transports them to a mounting station C that is mounted on a tap f of a tundish e to which the SN plate set is mounted.

In the set cartridge A, the upper and lower plates a and b constituting the SN plate set c are aligned with their respective nozzle holes d, and the nozzle holes d are arranged at regular intervals in a certain vertical or horizontal direction. It consists of the arrangement board 1 arranged by.

FIG. 2 shows S in the set cartridge A.
An example of a device for arranging the N plate set c so that its nozzle hole d faces the vertical direction will be shown. In the figure,
Reference numeral 2 is a vertical rod for inserting into each nozzle hole d of the sliding nozzle plate a and the fixed nozzle plate b, and a predetermined number of rods are arranged on the arrangement plate 1 at equal intervals. The horse member for doing is shown. The arrangement of the SN plate set c on the arrangement plate 1 is performed by inserting the rod 2 into the nozzle hole d of each of the plates a and b and placing the lower surface of the lower plate a on the horse member 3. .

FIG. 3 shows a modification of the vertical rod 2 and the horse member 3 on the arrangement plate 1 shown in FIG. As shown in the figure,
The vertical rod 4 has a head 5 that holds the nozzle holes d of the plates a and b so as not to shift, and is supported by a spring 6 so as to be elastically expandable and contractible. The vertical rod 4 of this structure uses a pneumatically expanded rod-shaped gripping member 7 (see FIG. 7) as the gripping mechanism 18 of FIG.
It is convenient for gripping by inserting and expanding means to insert into the plate. The head 5 of the vertical rod 4 is pushed down against the elastic force of the spring 6 by the inserting operation of the gripping member 7, and the plates a and b are expanded by the inward expanding operation. It is possible to grab at the same time.

Further, FIG. 4 shows a modified example of the horse member 3 shown in FIG. 1, which comprises a rubber pipe 9 attached to a round steel 8 supported by a support 7 attached to the arrangement plate 1. , Has a buffering function when the SN set is placed, and prevents the SN set from being damaged.

Further, FIG. 5 shows, as another modification of the arrangement in the set cartridge A, a state in which the plates a and b arranged on the arrangement plate 1 are arranged on separate arrangement plates 1 and 10.

FIG. 6 shows a state in which the nozzle holes d of the plates a and b are horizontally arranged on the mounting plate 1 as another modification of the arrangement in the set cartridge A.

Further, in FIG. 7, as another modification of the arrangement in the set cartridge A, three stages of refractory plates g are stacked on the arrangement plate 1 with their nozzle holes d vertically. An example of arrangement in the state is shown. As shown in the figure, three sets of three-stage refractory plates g are laminated on the arrangement plate 1 with a rubber disk 13 having an iron plate 12 for imparting strength interposed therebetween, for fixing nozzle holes. It is also possible to insert the pipe 14 and arrange it with the upper part thereof being supported and fixed by the rubber disk 15.

Returning to FIG. 1, the SN plate sets c from the set cartridge A are picked up one by one to
In the transport section B that transports to the mounting station C that is attached to the tap hole f of the tundish e to which the plate set is attached, the rod member 4 can move to the beam portion of the frame body 17 that runs on the rail 16 and can move up and down. The gripping mechanism 18 is suspended. Furthermore, the gripping mechanism 18 is rotatable by itself, and an openable / closable gripping member 19 is attached to the lower end thereof. The gripping mechanism 18 moves and descends to the mounting plate 1 of the set cartridge A, and then the gripping member 19 grips the SN plate set c arranged on the mounting plate 1 and the mounting / reversing device 20.
It is conveyed to the position of and is placed on the reversal plate 21. At this mounting position, the SN plate set c is fixed by the holding and fixing mechanism 22 on the reversing plate 21. From above the placed SN plate set c, the insertion rod-shaped heater 23
Is lowered and inserted into the nozzle hole d to preheat in preparation for operation. Then, the reversing mechanism 24 is operated to reversely move it to the position of the mounting station C to be attached to the tap hole f of the tundish e.

At the mounting station C, a turntable 25
It is placed on the carriage 26 and moves on the rail 27 to the position of the tap f of the tundish e. The rotary table 25 has an insertion rod 28 for inserting into the nozzle hole d of the SN plate set c.
Is provided on each surface of the rotary table 25, is inverted by the reversing mechanism 24 of the transport section B, and is inserted and held in the nozzle hole d positioned in the horizontal direction. The SN plate set c held by the insertion rod 28 is rotated by the rotation table 25,
The trolley 26 is oriented in the direction of the tap hole f, and is pushed into the tap port f by the movement of the carriage 26 to set. Then, the mounting is completed by a mounting device having a surface pressure applying device (not shown).

In this way, the SN plate set c can be mechanically, accurately and efficiently attached to the tap f of the tundish.

[0020]

The present invention has the following effects.

(1) The sliding nozzle plate can be safely attached and detached without manpower, and labor can be saved.

(2) Since it can be attached and detached in a set state, it saves time and is efficient.
