がある。 Generally, in vacuum heating or vacuum degassing equipment for a ladle containing molten metal, when the ladle lid is lifted and moved, or when the ladle body is moved with the lid lifted, a seal attached to the lid is used. The packing will be exposed to high temperature radiant heat and hot air from the molten metal. In order to prevent this, gasket protection devices have conventionally been provided, but this requires a drive means for the device, such as a fluid pressure cylinder, which makes the layout complicated and increases costs. It also has the disadvantage of being connected.

ンを保護することができるものである。 In contrast, the present invention aims to provide a gasket protection device for a vacuum ladle that can eliminate the above-mentioned drawbacks. A heat shield plate that covers the seal gasket on the lower surface of the lid with a link member pivotally connected to a support member suspended from a suspension beam or pedestal when the lid is raised, and opens in the opposite manner to the above when the lid is lowered. According to the present invention, the heat shield plate can be moved up and down using the vertical movement of the ladle lid without using any special drive device. The seal packing can be protected by automatic, timely, simple and reliable operation.

る。 In Figures 2 and 3, the upper end is the pedestal 8 as appropriate.
A bifurcated guide 11 having a sliding groove 10 is suspended from the lower end of the support 9 fixed to the suspension beam 1, and an upper connector is slidably connected to the groove through a pin 12. The rod 13 is connected to a lower connecting rod 15 by a turnbuckle 14, and the lower end of the lower connecting rod is connected to a pair of link plates 17 via a pin 16.
It is pivotally connected. Further, the same number of heat shield plates 19 having inwardly bent tongue pieces 18 which are to be divided into a large number of small pieces and placed around the lower circumference of the water-cooled ladle lid 3 are provided on the lower outer periphery of the lid. It is attached to a link plate 17 which is pivotally connected to a support bracket 20 which is provided via a hinge pin 21. In this case, for actual assembly, the link plate 17 is attached to the heat shield plate 19 in advance and the corresponding Pin the link board to pins 16 and 2
At 1, the lower connecting rod 15 and the support bracket 20 are respectively pivotally connected.

できる。 Next, to explain the operating mode of the device of the present invention having the above-mentioned configuration, as shown in FIG.
l While the pin 12 is lowered by 1 , the pin 12 moves into the groove 1 of the guide 11 fixed to the hanging beam 1 or the frame 8 with the support 9.
0 to the lower end, during which time the heat shield plate 19 does not operate, and as the lid continues to descend, the heat shield plate rotates in the direction of the hour hand around the hinge pin 21 at the lower connecting rod 15. The seal gasket is released from the protective state by moving the seal gasket, and the lid is set on the gasket seat or flange 6, resulting in the state shown in FIG. 3. In this case, there is a relationship l=l 1 + l 2 between the stroke l of the lid 3 and l 1 and l 2 , and l 1
By appropriately selecting and l 2 , the heat shield plate 19 and the packing seat or flange 6 can be operated with good timing without interference, and this timing adjustment can also be corrected by the turnbuckle 14.
