Apparatus for ladle < RTI ID = 0.0 >

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ladle apparatus, and more particularly, to a ladle apparatus capable of restoring a tread ring of a ladle.

In general, a ladle can be used as a container for holding molten metal such as molten iron, molten steel and the like and moving the molten metal while maintaining the temperature.

For example, the ladle may receive the refined molten steel therein, and after it is seated on the ladle turret, molten steel may be injected into the tundish. Here, when the molten steel contained in the ladle is injected into the tundish, the ladle is transferred to the slag discharge site using a crane or the like to remove the slag remaining in the ladle. At this time, it is possible to connect the main shaft of the crane to the trunnion which is formed on both sides of the ladle, and to transfer the slag to the slag discharge place so as to prevent the ladle from tilting by connecting the bogie to the tie ring connected to the lower side of the ladle.

When the ladle arrives at the slag discharge site, the slag disposal location is set by recommending the sovereignty and the soleplate, and then the slag disposal location is set, and when the soleplate is hoisted, the slag which remains in the ladle is discharged to the outside .

On the other hand, the tread rings are coupled to the stopper provided on the side of the ladle so as to be easily connected to the bobbin, and are detached from the stopper when the ladle is tilted. Therefore, after the ladle tilting, the tie ring should be reattached to the stopper for subsequent work. However, since the restoration work of binding the tread rings to the restraint is manually performed by the worker, the burden on the worker is increased, and it takes a lot of time.
