Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a side seal device for a twin-roll continuous casting machine.

[Prior Art] As shown in FIG. 4, a twin-roll continuous casting machine has two cooling rolls 1, 1 arranged parallel to each other and spaced apart from each other at an appropriate distance. A side seal plate 2 is provided to form a pool at the upper part between the rolls (a barrel seal plate may be provided in the axial direction above the cooling rolls 1, 1), and molten metal is poured into the pool. While being cooled by the cooling rolls 1, 1, the cooling rolls 1, 1 are driven to rotate in the direction of the arrow shown in the figure, and a slab 3 is continuously cast out from the roll gap between the cooling rolls 1, 1.

[Problems to be solved by the invention] However, in the conventional method described above, the side seal plate 2 for forming the pool of water needs to be made of a refractory material (for example, ceramics);
In cases where the side seal diameter is several meters, the side seal plate must also be large, and manufacturing such a large side seal plate from refractory material is extremely difficult and expensive. .

In view of these circumstances, the present invention forms the side seal plate in a substantially V-shape and consists of a plurality of fireproof seal plate blocks, making manufacturing easier and allowing for partial replacement. This is what I did.

[Means for Solving the Problems] The present invention is an attempt to solve the above-mentioned technical problem, and involves forming a pool of water from cooling rolls arranged in parallel and side seal plates arranged on both end faces of the cooling rolls. In the side seal device for a twin roll continuous casting machine, the side seal plate is formed into a substantially V-shape by a plurality of fireproof seal plate blocks,
The present invention also relates to a side seal device for a twin roll continuous casting machine, characterized in that the fireproof seal plate block is supported by a block support plate.

[Function] Therefore, in the present invention, the side seal plate has a substantially V-shape that follows the edge of the cooling roll, and is divided into a plurality of parts and supported by block support plates, so that the side seal plate can be refractory with small dimensions. The seal plate block allows for easy manufacture.

[Example] An example of the present invention will be described below based on the drawings.

FIG. 1 shows an example of the present invention, in which a side seal plate 2 provided at the width end of the cooling rolls 1, 1,
It is constructed in a substantially V-shape by two fireproof seal plate blocks 4a and 4b made of a fireproof material and having a curved shape that covers the ends along the outer circumferential shape of the cooling rolls 1 and 1, for example. Incidentally, since the necessary part of the side seal plate 2 made of the above-mentioned refractory material is the edge part of the cooling rolls 1, 1, it can be made into the above-mentioned approximately V-shape and further divided into two parts. Therefore, the side seal plate 2 is made smaller.

Further, on the outside of the side seal plate 2, a block support plate 5 is provided for integrally supporting the fireproof seal plate blocks 4a, 4b. In addition, a pressing seal plate 7 formed to match the approximately V-shaped fitting portion 6 formed by the fireproof seal plate blocks 4a and 4b is provided to form a hot water reservoir. That's what I do. Incidentally, since the pressing seal plate 7 does not come into direct contact with the cooling rolls 1, 1, it can be manufactured from a relatively inexpensive fireproof material.

Figures 2 and 3 show other examples of the present invention, in which the V-shaped fitting part 6 is fitted with the V-shaped fitting part 6 and prevents the molten metal from staying in the pool. A solid core 8 for directing the flow is provided, and the fireproof seal plate blocks 4a, 4
b is further divided into multiple parts. In the figure, numeral 9 indicates a tundish provided on the upper part of the core 8, and numeral 10 indicates a pouring hole.

In this way, the pressing seal plate 7 can be omitted by installing the core 8, and the problem that arises when the core is installed between the side seal plates can also be solved. In other words, when installing a core between the side seal plates, it is necessary to manufacture and set the core accurately according to the width (length) of the cooling roll, and the width of the core and the cooling roll are different. If this happens, it becomes impossible to press the side seal plate against the end face of the cooling roll, creating a gap and causing problems such as the inability to seal the molten metal.However, as mentioned above, the core 8 is According to the method in which the side seal plate 2 is fitted and supported by the core 8, the positioning of the side seal plate 2 with respect to the cooling rolls 1, 1 can be freely adjusted regardless of the core 8. Further, since each of the fireproof seal plate blocks 4a and 4b is further divided into a plurality of parts, the manufacturing thereof can be performed more easily and at a lower cost.

Note that the present invention is not limited to the above-mentioned embodiments, and various changes may be made without departing from the gist of the present invention.

[Effects of the invention] As described above, according to the side seal device of the twin roll continuous casting machine of the present invention, the side seal plate has a substantially V-shape along the edge of the cooling roll, and a plurality of side seal plates are provided. Since the fireproof seal plate block is divided into two parts and supported by the block support plate, it is possible to reduce the size of each fireproof seal plate block, thereby achieving an excellent effect that it can be manufactured easily and at low cost.
