Abstract

PURPOSE: A filler cover for a ladle and a device for injecting the same are provided to effectively prevent the missing of filler since filler piled more highly than the floor of a ladle is held in the space of a filler cover, so the filler is completely covered. CONSTITUTION: A filler cover(5) for a ladle(100) is placed on an ejecting hole(110). When ingot steel is held, the filler cover prevents the missing of filler(130) filled in the ejecting hole of the ladle. The lower cone(7) of the filler cover is formed below an upper plate(6) and comprises an inner space. Filler piled more highly than the floor of the ladle is held in the inner space of the lower cone.

Description

Ladle filler cover and its feeding device {LADLE FILLER COVER AND SUPPLY DEVICE OF THE SAME}

The present invention relates to a filler cover for a ladle and a feeding device thereof, and more particularly, a filler cover and a filler cover inserted to prevent a loss of a filler sealing the molten steel outlet prior to taking the molten steel into the ladle. To provide a configuration of a filler cover injecting device for transporting from the outside to be seated on the molten steel outlet inside the ladle, to effectively prevent the loss of the ladle filler and to perform the filling of the filler cover safely and efficiently. The present invention relates to a ladle filler cover and a feeding device thereof.

In general, steel mills take molten steel from ladles to ladles for refining and then transfer the refined molten steel to the machine, which is a post-processing facility. In the above, looks at the configuration of the ladle for conveying molten steel with reference to FIG.

Usually, the ladle 100 may be configured to receive high temperature molten steel by forming the inside of the shell as a refractory material, and may be installed in a bogie (not shown) to transfer the molten steel received inside the ladle 100. The molten steel outlet 110 is formed on the bottom surface of the ladle 100, and the gate 120 is formed on the outlet 110 to discharge molten steel in the ladle 100 to the outside. .

And look at the action of the ladle 100, the molten steel outlet 110 of the ladle 100 before closing the molten steel into the interior of the ladle 100 to the filler 130, the filler ( 130 is filled in the molten steel outlet 110 in the form of a powder and then sintered densely in the refining operation to close the molten steel outlet 110, and when the molten steel is opened, the sliding gate 120 at the bottom of the outlet 110 is opened. As the filler 130 is destroyed by the positive pressure, the molten steel inside the ladle 100 is pulled out. This process is called free open.

On the other hand, in taking the molten steel from the converter, when the filler 130 filled in the outlet 110 of the ladle 100 is lost by the molten steel falling in the initial stage of the molten steel, the molten steel to the gate 120. After the inflow hardened, the sintered layer does not break due to the static pressure of the molten steel, which leads to an unopening state. In order to prevent such a problem, the filler cover 140 is disposed on the upper side of the outlet 110 filled with the filler 130. Since the filler cover was prevented from being lost by molten steel, the filler cover 140 was not melted by hot molten steel after the tapping, so it did not affect the tapping.

However, in the case of the input of the conventional filler cover 140 as described above, the worker climbed on the structure around the ladle 100 and throw the filler cover 140 directly from the upper side of the ladle 100, such as Filler cover throwing operation not only insured the safety of the worker in a high-temperature workplace caused the risk of an accident, but also had an inefficient problem, such as re-throwing can not expect accurate throwing work.

In addition, while the filler 130 filled in the molten steel outlet 110 is usually stacked higher than the bottom surface of the ladle 100, the thrown filler cover 140 is a flat plate does not cover the filler 130 completely There was also.

The present invention is to solve the above conventional problems, and to provide a configuration of the filler cover for the ladle that can more effectively prevent the loss of the filler filled in the molten steel outlet of the ladle as well as the filler cover to the inside of the ladle It is an object of the present invention to provide a configuration of a filler cover input device for ladle that can be injected more safely and efficiently.

Ladle filler cover according to the present invention for achieving the above object, in the filler cover seated on the upper side of the outlet so as to prevent the loss of the filler filled in the outlet of the ladle when the molten steel is received, the lower side of the upper plate Characterized by the configuration of the filler cover for the ladle to form a lower cone having an inner space so that the filler stacked higher than the bottom surface of the ladle can be accommodated in the inner space of the lower cone.

And the present invention, while forming a vertical guide on one side and the upper end of the body having a vertical bogie drive motor for forming a pair of rotation shaft wound around the towing chain interlocked to transfer the rotational force with respect to the rotation axis, and A weight that binds one end of the bogie towing chain, a vertical bogie that binds the other end of the bogie towing chain and is guided up and down by a vertical guide, and a horizontal arm formed on the vertical bogie and having a horizontal arm drive motor. A horizontal arm inserted into the housing and the horizontal arm housing, the horizontal rack to which the pinion of the horizontal arm driving motor is coupled, is formed on one side of the horizontal arm, and is formed at one end of the horizontal arm, and has a vertical arm driving motor. Vertical arm housing and a vertical rack inserted into the vertical arm housing, the vertical rack to which the pinion of the vertical arm drive motor is coupled to one side and transported vertically Have different characteristics in the vertical arm and the configuration of the normal to the ladle cover for a filler to form a cover holder on the bottom of the chute cancer.

In addition, a turntable is formed on the upper side of the frame, but the body is formed on the upper side of the turntable to form a filler cover for the ladle to rotate the body, and a horizontal bogie on the upper side of the frame to form a body on the upper side of the horizontal bogie There is an additional feature to the filler cover input device for ladle to form a horizontal transfer to the body.

According to the present invention of the configuration as described above, it is possible to block the risk of accidents by securing the safety of the operator in a high temperature working environment by automating the transfer / input operation of the filler cover, and also to insert the filler cover in the correct position Therefore, the effective filler cover operation is possible. In addition, since the filler stacked higher than the bottom surface of the ladle is accommodated in the space portion of the filler cover, the filler can be completely covered, thereby effectively preventing the loss of the filler due to molten steel.
