Description

Detailed Description of the Invention

[0001]

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

[0002]

2. Description of the Related Art In a casting operation, in the case of continuously producing strip-shaped castings, a molten metal (hereinafter, referred to as molten metal) in a melting furnace is transferred and supplied into a tundish by a ladle. A continuous casting facility is used to draw the molten metal from the cooled mold with a drawing roll. If the molten metal is transported by a ladle when casting using this equipment, part of the molten metal will solidify and adhere to the inner wall of the ladle, and this residue will be heated and melted. Is tilted and the residue is drained from the ladle and removed.

The removal of residues by the conventional ladle tilting method will be described with reference to FIG. A transfer crane 31 hooked on a trunnion 22 provided on the outer wall of the ladle 21 conveys the ladle 21 above the discharge tank 33, holds the ladle 21 and is attached to the bottom of the ladle 21. The tilting crane 32 is hooked on the tilting jig 23 to tilt the ladle 21, and the slag 41 remaining inside the ladle 21 is discharged into the discharge tank 43. The inclination of the ladle 21 is returned to a predetermined angle, the residue solidified and fixed on the inner wall of the ladle 21 is heated and melted to form the molten metal 42, and the ladle 21 is tilted again to be the molten metal 42. The substance is poured from the ladle 21 and discharged into the discharge tank 43.

[0004]

In the removal of the residue by the ladle tilting method as described above, the residue in the ladle 21 inside the carrying crane 31 for reciprocating the ladle 21 between the melting furnace and the tundish is removed. Since it is used for a long time to remove, the production efficiency is very poor. Further, since the worker hooks the tilting crane 32 on the tilting jig 23,
The work is troublesome and the safety in the work is a problem.

[0005]

In order to solve the above-mentioned problems, in the ladle tilting device of the casting equipment according to the present invention, the ladle tilting devices are provided so as to face each other, and the ladle is supported so as to be interposed therebetween and the latitudinal direction. A pair of rotating plates in the form of a disc that can be rotated to, and a holder for fixing the ladle to the rotating plate,
A holder fixing means for fixing the holder to the rotating plate,
And a rotating means for rotating the rotating plate in the circumferential direction.

[0006]

In the ladle tilting device of the casting equipment having the above-described structure, the ladle is supported by the rotating plate, the ladle is fixed to the rotating plate by the holder, and the holder is fixed to the rotating plate by the holder fixing means. After that, by rotating the rotary plate by the rotating means, the ladle is inclined and the residue inside the ladle is discharged.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment in which the ladle tilting device for casting equipment according to the present invention is applied to continuous casting equipment will be described with reference to FIGS. 1 is a partial cross-sectional front view, FIG. 2 is a side view taken along the line II-II of FIG. 1, and FIG. 3 is a side view in which the ladle is tilted.

As shown in these figures, a pair of disk-shaped rotary plates 1 facing each other are provided with a concave cutout portion which communicates the axial center portion of the rotary plate 1 with the peripheral edge portion so as to form an opening at the peripheral edge. 1a are formed respectively. A plurality of connecting shafts 2 are provided between the rotary plates 1 so as to extend along the outer circumference of the rotary plates 1. The rotary plates 1 are integrated so that the rotary plates 1 are integrated with each other.
Are linked to. A plurality of pins 3a are provided along the peripheral edge of the rotary plate 1 at a predetermined interval.
Is doing. Below the rotating plate 1, there is a pin gear 3
A sprocket 4 that meshes with the sprocket 4 and a support roll 5 that rotatably contacts the outer periphery of the rotary plate 1 to support the rotary plate 1 are provided. These sprockets 4 have
The motor 6 is connected, and when the motor 6 is driven, the rotating plates 1 forming a pair rotate together.

A ladle 21 is provided in the notch 1a of the rotary plate 1.
Ladle support tools 7 for supporting each are provided. On the outer surface of the rotary plate 1 on the side of the cutout portion 1a of the rotary plate 1, a holding plate 8 which is a holding tool for fixing the ladle 21 to the rotary plate 1 has the same shape as the peripheral edge of the rotary plate 1. Each of the holding plates 8 is provided in the shape of a circular arc fan.
It is rotatably attached to the rotary plate 1 by a rotary shaft 9. These holding plates 8 have concave cutouts 8
a is formed respectively, and these notches 8a are loosely fitted in the trunnion 22 of the ladle 21 supported by the ladle support 7 when the holding plate 8 rotates about the rotation shaft 9. Has become.

A hydraulic cylinder 1 is provided on the side surface of the holding plate 8.
One end side of 0 is connected, and the other end side of the hydraulic cylinder 10 is
The holding plate 8 is connected to the outer side surface of the rotating plate 1, and the degree of rotation of the holding plate 8 is adjusted by a hydraulic cylinder 10. Fixing pins 11 which are holding means fixing means for fixing the holding plate 8 to the rotary plate 1 are provided on the outer side surfaces of the holding plates 8 so as to penetrate the holding plates 8, respectively. When the notch 8a of the holding plate 8 is engaged with the trunnion 22 of the ladle 21, the hydraulic cylinder 12 is fitted into the fixed hole 1b formed in the rotary plate 1.

Reference numeral 13 is a stopper plate for positioning the holding plate 8, 24 is a fireproof wall for protecting the ladle 21, and 43 is a discharge tank for discharging the residue in the ladle 21.

In order to remove the residue in the ladle with the ladle tilting device of such a casting equipment, the following procedure may be carried out.
That is, the ladle 21 is carried to the upper side of the rotary plate 1 by the carrying crane 31, the ladle 21 is placed on the ladle support 7, and then the carrying crane 31 is removed from the trunnion 22. The holding plate 8 is rotated to the position of the stopper plate 13 by the hydraulic cylinder 10 to remove the cutout portion 8a of the holding plate 8 from the ladle 21.
After being loosely fitted to the trunnion 22 of, the fixing pin 11 is fitted into the fixing hole 1b of the rotating plate 1 by the hydraulic cylinder 12,
The holding plate 8 is fixed.

When the rotary plate 1 is rotated by driving the motor 6 through the sprocket 4 and the pin gear 3, the ladle 21 is inclined with the rotation of the rotary plate 1 and the slag remaining inside the ladle 21 is rotated. 41 is discharged into the discharge tank 43. After the discharge is completed, the motor 6 is driven to rotate the rotary plate 1 in the direction opposite to the direction described above to return the ladle 21 to a predetermined angle, and the residue solidified and attached to the fireproof wall 24 of the ladle 21. Is heated and melted to form a molten metal 42. By driving the motor 6 again to rotate the rotary plate 1 and tilt the ladle 21, the molten metal 42 in the ladle 21 is discharged into the discharge tank 43.

Therefore, when the ladle 21 is tilted, the carrying crane 31 is not required, and the work by the operator in the vicinity of the ladle 21 due to the tilting work is not required.

Although the present embodiment is applied to continuous casting equipment, it can also be applied to general casting equipment.

[0016]

As described above, in the ladle tilting device of the casting equipment according to the present invention, the ladle is tilted by the rotating plate,
Since the residue inside the ladle is discharged, it is no longer necessary to use a crane for transporting the ladle, which greatly improves the production efficiency. Moreover, since it is not necessary to use a tilting crane, the work by the worker is facilitated, and
Work safety is improved.
