DEDLICE FOR OPENING CLOSING THE LADLE COVER}

The present invention relates to a detachable device for a reddle cover, and more specifically, to a device for removing a slag while removing the reddle cover by using a crane to the ladle cover used in the steelmaking process.

In general, the steel mill receives the molten steel from the converter in ladles and transfers it to the continuous casting operation, which is a post-process.It is used to cover the upper part of the ladle as a means to prevent the temperature drop of the molten steel during transportation. After transferring the ladle to the slag outside using a tilting to remove the slag by tilting the ladle, the slag is removed, the slag is recovered again and the molten steel is injected from the converter to perform the above-described operation continuously.

Describing the prior art to remove the ladle cover, especially the slag during the operation described above, when the molten steel is covered by the ladle to cover the ladle cover to be transferred to the subsequent casting process continuous crane sowing guide 10 both sides Kaba hook provided on the reddle cover 51 by operating the bobbin hook (20) and the bobbin hook (30) of the crane consisting of the hoist hook to the sovereign wire drum (11) provided in the After coupling to the hanger 52 to move the bobbin on the upper surface of the ladle (50) and then release the hook hook hook 52 and the bobbin hook, the ladle cover is to cover the upper part of the ladle. By moving so that the sovereign hook 20 is coupled to the ladle sovereign hanger 53 is coupled to move the crane in a continuous casting process.

In addition, the conventional technique for discharging the slag in the ladle completed the continuous casting operation is the sovereign hook 53 provided on both sides of the ladle by the sovereign hook 20 is coupled to the ladle port transferred to the slag port prior to the slag discharge The removal of the ladle cover 51 is required by the work.

Therefore, by using the sovereignty 20 to remove the ladle cover, the ladle is placed on the truck and the ladle cover is operated on the upper part of the ladle to be seated on the floor according to the signal of the signal operator.

When the ladle cover is seated on the floor, it increases the right to the right, and then runs the sovereign again to raise the ladle to the position where the slag is removed, then activates the right to bind the right hook hook 30 to the ladle tilting ring 54 and then raises the right again. Let's do it. As the right of security is raised, the ladle fixed to the sovereignty hook 20 is tilted to be tilted at an angle and the slag 60 in the ladle is discharged to the outside.

After slag discharge is completed, the ladle is recovered to the converter process and molten steel is injected again, and the above-described operation is continuously performed.

Therefore, the use of the crane is not only time-consuming, but also cumbersome in the conventional method as described above. In particular, in the converter process for operating a plurality of converters, the tapping of the converter is delayed and dropped due to the failure of the crane in time. There was a problem that molten steel could not be connected to follow-up work in a timely manner, resulting in reduced productivity and poor quality.

Therefore, the technical problem to be achieved by the present invention is to remove the ladle cover in a short time to solve the above-mentioned problems, and also to reduce the crane usage time by moving the ladle at the same time when the ladle cover is removed. After removing the ladle cover by removing the ladle cover and lifting the ladle by using the crane again, the ladle cover can be lifted and removed continuously by lifting the ladle cover while the ladle is hanging on the sovereign hook. It provides a device to reduce the crane usage time.
