Abstract

(57) [Summary] [Constitution] This is a continuous casting facility in which the mold 2, the vibration device 3, the support roll group 4, and the dedicated guide roll group 5 are supported on the same exchanging carriage 7. [Effect] Since the mold, the vibration device, the support roll group, and the dedicated guide roll group are collectively supported by one exchange trolley, the exchange trolley is used when changing the size of the slab, that is, when changing the mold. Just replace it,
Therefore, compared with the case of carrying in and out the mold, the vibration device and the support roll group side, and the dedicated guide roll group side separately, the mold changing work can be made very short,
The operating rate can be improved.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to continuous casting equipment.

[0002]

2. Description of the Related Art Generally, as shown in FIG.
A continuous casting facility for continuously casting a slab such as a beam blank is arranged directly below the mold 51, a vibrating device 52 for placing the mold 51 and applying vibration to the mold 51, and a mold 51. Support roll group (consisting of a segment in which a plurality of support rolls 53b are provided on a support frame 53a) 53, and this support roll group 5
Dedicated guide roll group (consisting of segments in which a plurality of dedicated guide rolls 54b are provided on the support frame 54a) 54 for guiding the cast slab from No. 3, and the cast strip from this dedicated guide roll group 54 Common guide roll group (comprising a segment in which a plurality of common guide rolls 55b are provided on the support frame 55a) for
It is composed of a pinch roll group (not shown) for drawing out the slab.

By the way, conventionally, the mold 51 has a vibrating device 52.
The support roll group 53 is also integrally supported by the vibrating device 52, and the dedicated guide roll group 54 is placed on the exchange carriage 62 via the support frame 61.

In this configuration, when the mold 51 is replaced, the mold 51 and the support roll group 5 are used by using a crane.
After suspending 3 together, the special guide roll group 54 is pulled out by the exchange carriage 62, the new mold and the support roll group are integrally arranged by the crane, and the new dedicated guide roll group is arranged on the strand by the exchange carriage. Had been delivered to.

When the dedicated guide roll group is not placed on the exchange cart, the dedicated guide roll group is also hung by using a crane.

[0006]

According to the above-mentioned conventional structure, when changing the size of the slab, the mold and the support roll group must be integrated and lifted by a crane to be replaced, and the mold and the support roll group must be mounted on the replacement cart. It is also necessary to replace the dedicated guide roll group that has been cut, and therefore this type change work requires a very long time, and in the case of multiple strands, it may take about 4 to 6 hours, and the operating rate is high. There was a problem of lowering.

Therefore, an object of the present invention is to provide a continuous casting facility which can solve the above problems.

[0008]

In order to solve the above-mentioned problems, the continuous casting equipment of the present invention comprises a mold, a vibrating device for placing the mold to apply vibration, and a support arranged immediately below the mold. In a continuous casting facility having a roll group, a dedicated guide roll group for guiding slabs from this support roll group, and a common guide roll group for guiding slabs from this dedicated guide roll group, The mold, the vibration device, the support roll group and the dedicated guide roll group are supported on the same exchange carriage.

[0009]

According to the above construction, the mold, the vibrating device, the support roll group and the dedicated guide roll group are collectively supported by the single exchange trolley, so that when the size of the slab is changed, the exchange trolley is used. It is only necessary to replace it, and therefore the mold changing work can be made very short.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIG. Reference numeral 1 denotes a continuous casting facility for continuously casting a slab, such as a bloom, a mold 2, a vibrating device 3 for placing the mold 2 and applying vibration to the mold 2, and directly below the mold 2. A group of support rolls (consisting of segments in which a plurality of support rolls 4b are provided on the support frame 4a) 4 and a group of dedicated guide rolls (guide frame 5a for guiding the slab from the support roll group 4) And a common guide roll group for guiding the slab from the special guide roll group 5 (a plurality of common guide rolls 6b on the support frame 6a). 6) and a pinch roll group (not shown) that pulls out the slab. ) And the mold 2, the vibrating device 3 on which the mold 2 is placed, the support roll group 4, and the dedicated guide roll group 5 are supported on the same exchanging carriage 7 via the support frame 8. It was done.

The dedicated guide roll group 5 is to be replaced together according to the mold 2 to be replaced,
Further, the shared guide roll group 6 is not necessarily replaced together with the mold 2.

The exchange cart 7 has a predetermined floor surface 1
A traveling wheel 9 and a traveling drive device (not shown) that can travel freely on a guide rail 12 disposed on the vehicle 1 are provided.

Incidentally, fixing frames 13 for fixing the position of the exchange cart 7 are erected on both sides, and after the exchange cart 7 is moved to a predetermined position, for example, via a cotter or an uneven portion, The exchange cart 7 is fixed to the fixing base 13 side.

In the above-mentioned structure, when changing the size of the slab, that is, when the mold 2 is replaced, the couplings such as hydraulic pipes and cooling water pipes are removed, and the exchange cart 7 is used.
After being detached from the fixing base 13, the exchanging carriage 7 is caused to travel on the guide rail 12 by the traveling drive device to be detached from the strand. And a new mold,
Another exchange carriage supporting the vibrating device, the support roll group and the dedicated guide roll group may be moved into the strand and fixed at a predetermined position.

Thus, when replacing the mold,
The vibrating device, support roll group and dedicated guide roll group are collectively supported by the exchange cart and are changed at once, so the mold, vibrating device and support roll can be used by using a crane, etc. as before. Compared with the case where the group side and the dedicated guide roll group side are carried in and out separately, the mold changing work can be made very short. For example, it can be about 30 minutes.

When there are a plurality of cast strands, for example, 2 strands or 3 strands are mounted on one exchange carriage.
The equipment for the strand is supported.

[0017]

As described above, according to the structure of the present invention, since the mold, the vibration device, the support roll group and the dedicated guide roll group are collectively supported by one exchange carriage, the size of the cast piece can be obtained. When changing, the exchange cart only needs to be replaced.Therefore, as in the conventional case, when using a crane or the like to separately carry in and out the mold, the vibration device and the support roll group side, and the dedicated guide roll group side. In comparison, since the mold changing work can be extremely shortened, the operation rate can be improved.
