Description

Multipurpose Apparatus for clearing slag of pit}

The present invention relates to the now attached to the pit wall (P) and the furring hole (PH) of the molten iron preparation copper for carrying out skimming (SKIMMING) work in the steel mill, more specifically, The present invention relates to a multi-purpose pit now-removing device that removes the current attached to the part more efficiently and uses a single piece of equipment.

In general, in order to make the molten iron drawn from the blast furnace of the iron making process of steelmaking into refined molten steel, it is transferred to the crossover truck (T) that rides on the rail (R). Since it contains slag and impurities, it is moved to the molten iron preparation to remove it.

The cross-talk vehicle (T) arrives at the charter preparation voyage and leaves the ladle (L) waiting on the bottom of the PIT through the POURING HOLE to remove the slag of the charter vessel contained in the ladle. In order to move to the skimmer S through the ladle transfer car TC, slag removal is performed.

In this process, the molten metal is attached to the inner wall of the furring hole (PH) in the process of moving out through the furring hole, and a hard current is generated. Also, the hot molten water splashes in the ladle (L) and attaches to the inner wall of the pit. It is now hardened. In addition, when the electrode rod ER is loaded into the ladle L to carry out the impurity removing operation (desulfurization) before moving to the skimmer, a high temperature molten iron is splashed and sintered to the inner wall of the pit while skimming. This spring is attached to the inner wall of the pit, and as this process is repeated many times, a large amount of current is generated in the furring hole and the inner wall of the pit.

If a lot of jams are caught in the furring hole, the hole of the furring hole is reduced, and workability is reduced. If a lot of jams are jammed in the inner wall of the pit, the width of the inner wall of the pit is narrowed, which acts as a jamming element when the ladle transfer car moves the ladle. In addition, there is a problem that now attached to the wall during ladle transfer car maintenance and pit floor cleaning is a significant risk factor.

Conventionally, in order to remove the current attached to the inner wall of the pit, a breaker is attached to a general excavator which is currently used as an excavating equipment, and the pit inner wall is removed by putting it into the pit by a crane, but the movement of the excavator is limited. There is a problem that cannot be removed now.

In detail, the breaker which is now attached to the arm of the removal vehicle, the working efficiency is greatly improved as the movement is free. However, the conventional now removed vehicle is applied to a general excavator as shown in FIG. 2, the vertical joint movement is smoothly performed by the boom and the arm, and since the left and right turning motion depends on the turning of the main body, the left and right turning motion is very slow and Limited. In addition, because the structure of the breaker is impossible to turn, it could not be removed more efficiently.

In addition, because of the narrow working space for the removal of the inner wall of the furring hole, it was very dangerous and it took much time for the removal work now because it was removed manually with the tool or hand breaker by manpower. This raises a number of problems, including increasing the risk of an outbreak.

The present invention was devised to solve the conventional problems as described above, an object of the present invention is a charter preparation multi-purpose pit now removing device for more effectively removing the now attached to the inner wall of the pit and the furring hole with one equipment To provide.

And another object of the present invention, the dozer device that can remove the inner wall of the pit and clean up the now fallen on the floor, and the wheel that can ride the rail in the removal of the furring hole now, the removal now This agile and quick-to-use charter preparation multipurpose now removal device is provided.
