[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ladle changing device having a pot lid in a continuous casting facility.

[0002]

2. Description of the Related Art A conventional technique is disclosed in, for example,
There is a ladle support cart disclosed in Japanese Patent Application Laid-Open No. 6233/1979 and Japanese Patent Application Laid-Open No. 54-137434. The feature of these technologies is that the ladle on the ladle support trolley is supported on the trolley,
It is not intended to suspend a pot or a pot lid.

[0003] Also, Japanese Patent Application Laid-Open No. 01-75166,
JP-A-63-72472, JP-A-01-2095
There is an attaching / detaching device for a heat retaining lid disclosed in Japanese Patent Application Publication No. 6-206, but the feature of these technologies is that a pot lid lifting / lowering device is independently installed as a dedicated device. Usually, the pot and the pot lid are detached by an overhead crane placed on the continuous casting facility building.

[0004]

[Problems to be solved by the invention]
When starting continuous casting, when the pot containing molten steel is tapping out of the pot at the pouring position, if there is no pot lid, the temperature of the molten steel in the pot will drop significantly, greatly affecting the product quality Therefore, it is necessary to provide a dedicated moving and lifting device for replacing the pot and attaching and detaching the pot lid, and when using an overhead crane, etc., it will overlap with other work etc. Giving unnecessary waiting time.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and provides a ladle exchanging apparatus in a continuous casting facility which can replace a ladle with a pan lid at the same time as exchanging the ladle. The purpose is to do.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention is directed to a ladle exchanging vehicle having a ladle exchanging truck and a ladle elevating device capable of traveling on a ladle supporting cart. It comprises a pot lid, a hanging hook and a wire for suspending the pot lid, and a hook and a wire for preventing the pan cover from resting.

[0007]

According to the present invention, a hook for suspending a pot lid is provided on the frame of the ladle elevating device of the ladle changing apparatus, and the hook is connected to a wire, and one side of this wire is connected to the pot lid. A plurality of these hooks and wires are provided on the frame of the lifting device. Further, a hook and a wire for preventing the pan cover from oscillating are also arranged on the frame of the lifting device so that the pan cover does not swing during the vertical movement. Since the hook and the wire for suspending the pot lid and the hook and the wire for preventing the pan lid from being set on the frame of the elevating apparatus are thus installed, the lid can be opened and closed only by the operation of the elevating apparatus when replacing the ladle.

[0008]

Next, a specific description will be given based on an embodiment shown in the drawings. 1 and 2 are schematic explanatory views of the ladle changing device of the present invention. FIG. 1 shows a side view, and FIG. 2 shows a plan view.

The ladle changing cart 1 is disposed on the garter 2 of the ladle support cart 12 and runs on the garter 2. Ladle change trolley 1 has a suspension ring 3 for hanging the pot
And a pan lid hanging hook 4 and a pan lid steadying hook 5. The pan hanging ring 3 is raised and lowered by a pan lifting cylinder 7 while being guided by a lifting guide roller 6. Becomes possible.

FIG. 3 is a sectional view of the ladle changing cart 1 according to the present invention, showing a state in which the pan 15 and the pan lid 16 are loaded. The pan suspension hanging ring 3 can be tilted by the suspension ring tilting cylinder 8, and the pan 15 can be detached from the trunnion shaft 9. Pot lid hook 4 and pot lid side hook 17
And the pan cover hanging wire 19 attached between the pan 1
Since the pot lid 16 is being put on 5, it is in a loose state. Similarly, the pan cover steadying wire 20 attached between the pan steady rest hook 5 and the pan lid steady rest hook 18 is also in a loosened state.

The pan 15 is lifted when the pan elevating frame 14 is raised by mounting the hanging ring 3 for hanging on the trunnion shaft 9 of the pan 15. At this time, pan lid 16
The upper pot cover hanging wire 19 remains loose, and there is no problem in transporting the pot 15.

FIG. 4 is a cross-sectional view of the ladle changing cart 1, showing the pot lid 16 being lifted. The pan lid 16 is lifted by the pan lid suspending wire 19 of the pan elevating device 13, and the pan lid steadying wire 20 is stretched. In this state, the pan lid can be transported.

FIG. 5 shows a detachable state of the pan lid and a state of the pan lid hanging wire 19 by the pan lid hanging tool. The pan lid steady rest wire 20 is not shown for simplicity. FIG. 5A shows the pot lid 1 with the pot lid hanging wire 19 attached to the pot elevating frame 14 of the ladle changing trolley 1.
6 shows a state where it is suspended.

FIG. 5B shows a state in which the pot raising / lowering frame 14 is at the lower limit position, the pot 15 is set at the casting position, the pot cover 16 is also at the lower limit position, and the pot cover 16 is set on the pot 15. Show.

FIG. 5C shows a state in which the pan lifting frame 14 is at an intermediate position and the pan lid 16 is cut off from the pan 15.

FIG. 5D shows a state in which the pan lifting frame 14 is lifted together with the pan 15 with the pan lifting frame 14 at the upper limit position. Therefore, the pot hanging wire 19 is shown in a loosened state.

FIG. 6 shows a pot lid-side hanging hook 17 above the pot lid.
And the pot lid side steady rest hook 18 are shown.

FIG. 7 shows a state of the pan cover hanging wire 19 and the pan cover steadying wire 20 when the pan cover 16 is lifted by the pan lifting frame 14.

[0019]

[Effects of the Invention] According to the present invention, a ladle exchange trolley on a ladle support trolley can be used on a ladle-exchange trolley without using an overhead crane, regardless of the working state of the overhead crane, on a pot containing molten steel for heat insulation. Since the pan lid can be set quickly, the preparation time can be significantly reduced, and the temperature of the molten steel in the pan is reduced, leading to an improvement in the quality of the slab. Also, without adding one overhead crane or installing a dedicated device for the pot lid, it can be easily incorporated into the ladle exchange trolley, and equipment costs can be reduced.
