Description

Ladle Rotation Hot Repair Base

The present invention relates to a ladle pedestal used for repairing the ladle, and more specifically, the hot-rolling member having fluidity is filled in the repair part by freely raising and lowering the ladle and freely rotating it at a desired angle. The invention relates to a ladle rotating hot repair pedestal that has been improved to prevent damage to the refractory and to improve the life of the ladle.

In general, the inner wall of the ladle is divided into metal lines and slag lines, so that refractory is used.In slag, MgO-C refractory is difficult to penetrate slag, and alumina-magnesia is used for metal line. The use of castable refractory is common.

In addition, when an abnormality occurs in the slag component in the ladle, abnormal erosion occurs in the ladle slag. When slag is eroded and repaired by non-aqueous hot element (Kneader material), the water-repellent effect is greatly increased and the service life of the ladle can be extended.

In general, the hot repair of the ladle is used hot spray repair, thermal spray repair, patching repair method. In the above, hot spraying and thermal spraying can be repaired on the vertical and horizontal parts of the ladle, but water-based spraying is limited in use because it causes rapid temperature change to the base of the repairing part and damages the base material. Although the effect of repair is great without adversely affecting the thermal spraying, it is not generalized due to the high cost of thermal spray material and repair equipment.

In addition, patching repair takes a long time to repair a wide area because it is attached and attached to the local eroded portion of the ladle refractory in a small amount, it can be repaired only in the repair direction in the horizontal direction. This is because, as shown in Figure 3, the conventional ladle support can only be repaired by laying the ladle in one direction.

That is, the conventional ladle mounting bracket 100 as described above has a structure in which the ladle 110 is fixedly seated on the upper portion, so that patching repair cannot be performed on the vertical portion and the inclined portion of the ladle 110, and the repair is performed. To do this, there is a problem that a worker must enter the ladle directly and cool to a workable temperature.

In addition, these hot small members (Kneader materials) can be used only on horizontal parts because they contain their own fluidity that fills the eroded parts while flowing and forming a liquid phase by melting the pitch and resin contained therein. It can't be used because it flows down the vertical wall. Therefore, in order to repair the vertical wall surface of the ladle with a non-aqueous hot element having magnetic fluidity, an apparatus for laying the ladle down and rotating is required.

The present invention is to solve the conventional problems as described above, its purpose is to freely rise and fall of the ladle and free rotation of the desired angle, so that the hot small member having fluidity is filled and repaired by itself It is an object of the present invention to provide an improved ladle rotating hot repair pedestal to prevent damage to the refractory, to improve the life of the ladle, and to reduce the raw unit of the refractory used.

In order to achieve the above object, the present invention provides a ladle pedestal used for repairing a ladle, the base having a predetermined size; A plurality of hydraulic cylinders mounted on an upper portion of the base, the rods being disposed toward the upper side, and arranged in pairs before and after each; A rotating mechanism having a plurality of lifting blocks mounted on the rods of the pair of hydraulic cylinders, respectively, and having a plurality of rollers rotatable above the respective lifting blocks; A driving motor for rotating any one of the rollers on the lifting block on a support projecting to one side of the lifting block, and rotating the rollers by rotating the rollers by operation of the driving motor. ; And a hydraulic pump for operating the paired hydraulic cylinders; By providing a ladle support provided with a back.

Hereinafter, the present invention will be described in more detail with reference to the drawings.

Ladle pedestal (1) of the present invention is a metal line (Slag) and slag line (Slag Line) erosion of the ladle 110 appears wide to lay the ladle 110, when repairing to the horizontal as well as vertical parts When it is necessary to repair the ladle 110 by rotating the ladle repair bracket (1) so that the vertical portion becomes a horizontal portion is to ensure that the hot small member having a magnetic fluid is filled in the repair portion by itself.

As shown in FIG. 1, the ladle pedestal 1 of the present invention includes a base 10 of a predetermined size, and a plurality of hydraulic cylinders 20 are mounted on an upper portion of the base 10. The hydraulic cylinders 20 have a structure in which the rods 22 are disposed toward the upper side, respectively, and are arranged in pairs before and after.

In addition, the rods 22 of the pair of hydraulic cylinders 20 are respectively equipped with a rotary mechanism 30 for rotating the ladle 110, which is a plurality of hydraulic cylinders 20 rods 22. Has a plurality of lifting blocks 32 mounted on the lower surface, respectively, and has a plurality of rollers 35 rotatable above the respective lifting blocks 32. Thus, the rotary mechanism 30 has a structure that can be rotated on the roller 35 when the ladle 110 is placed horizontally on the upper portion of the roller 35, the lifting block 32 is a hydraulic cylinder 20 By varying the height of the pair of rods 22 to advance, the height of the front and rear can be made different.

Then, the driving mechanism 40 is mounted to one side of the elevating block 32, the driving mechanism 40 is the elevating block 32 on the support 42 protruding to one side of the elevating block (32). A drive motor 45 for rotating any one of the upper rollers 35, and the rollers 35 are rotated by the operation of the drive motor 45 so that the ladle 110 is placed on the roller 35. To rotate. The drive motor 45 is equipped with a pulley 47a on its rotating shaft, and the belt 48 is caught by the pulley, and the belt 48 is caught by a pulley 47b formed on the central axis of one roller 35. As one of the plurality of rollers 35 on the lifting block 32 by the operation of the drive motor 45 is configured to rotate.

And, it has a hydraulic pump 50 for operating the paired hydraulic cylinders 20, respectively.

Ladle pedestal 1 of the present invention configured as described above is horizontal ladle 110 to repair the internal refractory material on top of the roller 35 is rotatably mounted to the lifting block 32 as shown in FIG. To rest. In addition, the hydraulic pump 50 is operated to adjust the height of the ladle 110 mounted on the elevating block 32, and a plurality of hydraulic cylinders 20 pairs holding the elevating block 32 are operated to operate the hydraulic pump 50. The rod 22 is to raise the elevating block (32).

In this state, when a hot element (Kneader material) is loaded into the ladle 110 and the driving motor 45 is operated, the ladle 110 on the roller 35 is rotated by rotating the rollers 35. Will be rotated. In this case, the speed at which the drive motor 45 rotates the ladle 110 should be equal to each other, and for this operation, the driving motor 45 is started to operate in synchronization with each other.

Therefore, according to the present invention, the ladle 110 by lying on the rotary roller 35 can be rotated 360 ° in the ladle 110 lying down, the rotary roller 35 is the height, up and down adjustment and driving The rotation speed by the motor 45 is adjusted so that the maintenance part of the ladle 110 is adjusted horizontally or inclined by adjusting the height of the front and rear of the rotary roller 35.

Therefore, the refractory repair hot-small member (Kneader material) inserted into the ladle 110 placed horizontally as described above can easily penetrate into the repair portion of the refractory to achieve effective refractory repair work.

As described above, when the ladle rotation hot repair pedestal 1 of the present invention is applied at the time of repairing the ladle 110, the repair part can be maintained horizontally and repaired, so that the fluidity is large at the hot spot, thereby repairing the vertical part. You can use the hot baking repair material. Therefore, it is possible to suppress damage of the built-in refractory of the ladle 110, thereby extending the service life of the ladle 110, thereby reducing the cost of maintenance work by reducing the raw unit of the used refractory is obtained.
