Description

Mold vibrator corresponding to dimension change of mold for continuous casting {MOULD OSCILLATOR CORRESPONDING TO DIMENSION CHANGE OF MOULD FOR CONTINUOUS CASTER}

The present invention relates to a mold vibrator, which is a primary cooling means of molten steel injected into a mold from a tundish during continuous casting, and more particularly, to secure a space for installing auxiliary equipment around the mold when the size and shape of the mold are changed. At the same time, the present invention relates to a mold vibrator for changing the dimensions of a mold for continuous casting, which enables the mold to be mounted without changing the main body.

In general, the continuous casting machine, as shown in Figure 1, ladle 2A (2B), the ladle 2A (2B), the ladle that is completed in the steelmaking process, the ladle to move to the tundish 4 Turret (1), ladle shroud nozzle (3) for conveying the molten steel of the ladle (2A) (2B), tundish (4) acting as a funnel, mold vibrator (5) for primary cooling the injected molten steel And a secondary cooling stand 6 combined in segments.

In particular, the mold vibrator (5) is a member that allows the mold itself to vibrate up and down to prevent fusion between molten steel and the copper plate when the molten steel passes through the mold. INMO MOULD such as is disclosed.

The in-mold mold is provided with rolling elements 7 at both ends to support the rear side of the mold holder 13 of the copper plate mold 8 on the vibration frame 11 vibrated by the hydraulic cylinder 12.

In addition, there is also disclosed a resonant mold (RESONANCE MOULD) that uses a spring called a leaf (AFR) to fix the mold and holder to a support and to oscillate up and down with a hydraulic cylinder (EP 0468607).

However, these techniques have a disadvantage in that the mold holder 13 itself must be replaced to match the size and shape of the mold because there is no appropriate countermeasure when the size and shape of the mold is changed by fixing a mold of a constant size.

In addition, the width change device of the continuous casting mold to change the length of the frame for fixing the mold when the width of the mold changes [DEVICE FOR CHANGING WIDTH OF CONTINUOUS CASTING MOLD, JP9308947 (European Patent Registration: Japanese Patent Laid-Open No. Hei 9-308947)] Although it is disclosed, this also has a disadvantage in that it is not appropriate because the lack of space to install the accessory equipment, such as hydraulic cylinder when changing the size of the frame.

The present invention has been devised to solve this problem in view of the above-described problems of the prior art, and even if the size and shape of the mold is changed during playing, the frame supporting the mold is changed without replacement of the mold holder, thereby enabling quick response. It is also an object of the present invention to provide a mold vibrator corresponding to the size change of the continuous casting mold, which makes it possible to secure the installation space of the accessory equipment.

The object of the present invention is to have a mold, a fixed frame which is fixed to the outer surface of the mold and movable left and right, fixed to each end of the fixed frame and free to slide and fixed, and a fixed plate to which the fastener is fixed It is achieved by including a mold holding member which is installed orthogonal to the fixed frame, and a guide package which is tightly fixed by the sliding support frame provided on both ends of the mold holding member and having a plurality of rolls with fluidity .

Hereinafter, a preferred embodiment according to the present invention will be described in more detail according to the accompanying drawings.

3 is a plan sectional view showing an installation state of the mold vibrator according to the present invention.

According to Figure 3, the subject innovation of the mold (8) 10, the fixing frame 18 for fixing the mold (8) 10, and a fastener for variably fixing the fixing frame (18) to a predetermined position ( 19), the mold fixing member 14 to which the fastener 19 is fixed, the guide package 15 provided at both ends of the mold fixing member 14, and the removal and spacing adjustment of the mold fixing member 14; It consists of a sliding support frame 16 for.

The molds 8 and 10 are installed to allow width and length deformation.

In addition, a fixing frame 18 for supporting and fixing both sides of the long sides of the molds 8 and 10 is provided.

The fixed frame 18 is mounted on the fixed plate 17 provided at the lower end of the mold fixing member 14 shown in FIG.

Of course, it is preferable to install the fixing frame 18 so that the fixed frame 18 is not easily slid by forming grooves of a predetermined interval in the shape of irregularities rather than simple shapes.

In addition, fasteners 19 are fixed to both ends of the fixing frame 18, respectively.

The fastener 19 not only smoothly guides the left and right movement of the fixing frame 18 but also performs a function of firmly fixing the fixing frame 18 so that the fixing frame 18 is not easily shaken or moved at the position after the fixing frame 18 is moved.

As shown in FIG. 4, the mold fixing member 14 includes a hydraulic cylinder 12 directly below the mold fixing member 14.

The hydraulic cylinder 12 is a member that performs the function of vibrating the molten steel so that it is not easily fused to the inner wall of the mold (8) 10, it is closely connected to the mold fixing member (14) installed on the vibration frame (11). do.

The guide package 15 is a member installed at both ends of the mold fixing member 14, and is dust-proof that the mold fixing member 14 is severely flowed in the left and right directions by the vertical vibration of the hydraulic cylinder 12. Perform the function.

To this end, the guide package 15 has a plurality of rolls (16-2), the rolls (16-2) are connected to the sliding support frame 16 is installed to be moved in the front and rear direction.

The sliding support frame 16 has a rotatable operating handle 16-1 fixed to the roll shaft 16-4 on one side thereof and the roll shaft 16 movably by manipulation of the operating handle 16-1. And a roll fixing plate 16-3 connected to -4) and the roll 16-2 provided on the roll fixing plate 16-3.

In addition, the rolls 16-2 are formed to be curved in the center thereof so as to easily press the ends of the mold fixing members 14.

In addition, these rolls 16-2 firmly press the mold fixing member 14 so that the mold fixing member 14 cancels the front, rear, left and right position error generation with respect to the mold reference line.

In addition, since they are not fixed through any fixing means but are fixed and supported by the pressing action of the uneven shapes, the replacement is very easy.

The present invention having such a configuration guides the molten steel from the tundish 4 to form the size and shape of the set mold vibrator, and performs the primary cooling action with periodic vibration so that the molten steel is not fused to both sides of the mold. Will be done.

This operation process is the same as before.

If, at this time, the mold work of different size and shape is required, the mold fixing member is operated at the same time as the operation of the operation handle 16-1. By changing the position of the fixed frame 18 by operating the 14 and the fastener 19, it is possible to quickly reset the mold size and shape.

This consists of a simple dismantling and locking operation of the fixed frame 18 and the mold fixing member 14 and the fastener 19, the guide package 15, and the sliding support frame 16, which are fixed to each other by a pressing action. You lose.

In addition, the mold fixing member 14 is made of a plurality of fixing means as in the prior art does not have to fix the mold (8) 10 and is easy to change the position to ensure sufficient installation space of other accessory equipment.

Then, when the size and shape of the mold is reset, the mold operation may be continued.

As described in detail above, the mold vibrator corresponding to the dimension change of the continuous casting mold according to the present invention provides the following effects.

First, since the mold holder to be replaced every time the mold size and shape is changed, the space can be secured so that it can be easily installed without interference.

Second, by providing the mold fixing member that responds quickly to the size change of the mold, it plays the role of the mold holder which is replaced every time the size of the mold changes, thereby improving workability, simple structure, and easy operation. to provide.
