ク鋳型１との摩擦で損傷を受ける、等の問題があった。[Problem to be solved by the invention] However, in the above-mentioned continuous casting machine, since the side of the side dam block 4 facing the mold space 3 thermally expands, the side dam sandwiched between the upper and lower mold blocks 1 If the block 4 was tightly packed, there were problems such as the thermal expansion part of the side dam block 4 being damaged by friction with the block mold 1 during casting or when changing the width of the side dam block 4. .

的としてなしたものである。In view of the above-mentioned circumstances, the present invention provides a gap corresponding to the thermal expansion between the block mold and the side dam block on the side facing the mold space 3 even if the side dam block thermally expands.
This was done to prevent the side dam block from being strongly pressed between the upper and lower mold blocks, thereby preventing damage to the side dam block during casting and when changing the width of the side dam block.

えている。[Means for Solving the Problems] The present invention connects a large number of block molds to form an endless track mold, and moves the endless track mold up and down so that opposing surfaces move in the same direction. An endless track in which a side dam is arranged to form a mold space, and a number of side dam blocks are connected on both sides of the mold space in the width direction of the slab to form an endless track, and the side dam is movable in the width direction of the slab. The continuous casting machine has a configuration in which a gap is provided in a portion of the side dam block facing the mold space on the side facing the block mold.

い。[Function] The side of the side dam block facing the mold space eliminates the gap due to thermal expansion, and the upper and lower surfaces become almost flat and adhere tightly to the block mold, preventing molten metal from entering between the block mold and the dam block. Furthermore, even if the width is changed during casting, the thermal expansion part of the side dam block will not be damaged.
［実 施 例］
以下、本発明の実施例を添付図面を参照しつつ説明する
。[Example] Hereinafter, an example of the present invention will be described with reference to the accompanying drawings.

嵌入せしめる。A carriage 13 that can be moved in the widthwise direction of the slab by a hydraulic cylinder 12 is disposed on both sides of the mold 2 made up of a large number of block molds 1 in the width direction, and a guide body 14 is disposed on the carriage 13. The guide body 14 is provided with an endless track-shaped guide groove 15 extending in the horizontal direction, and the endless track-shaped side dam 5 is formed by connecting a large number of side dam blocks 4 with springs 19 as shown in FIG. A vertical guide is disposed horizontally below the guide body 14 along a guide groove 15, and the side dam block 4 is supported by a horizontal support roller 16 disposed on a cart 13, and is pivotally supported by the side dam block 4. The roller 17 is fitted into the guide groove 15 of the guide body 14 in a movable manner.

るため、サイドダムブロック４の上下面は平坦になる。The side dam block 4 is supported by horizontal support rollers IB and moves while being guided by the guide grooves 15 of the guide body 14 via the vertical guide rollers 17. Also side dam block 4
Since the side facing the mold space 3 thermally expands and the recess 18 disappears, the upper and lower surfaces of the side dam block 4 become flat.
このため、ブロック鋳型ｌとサイドダムブロック４とは
密着し、この部分に溶湯が入り込まないため、パリの発
生が防止できる。For this reason, the block mold l and the side dam block 4 are in close contact with each other, and molten metal does not enter into this part, so that generation of paris can be prevented.

-1 and 4-2, 4-1 thermally expands in the heating zone portion, and 4-2 does not thermally expand in the cooling zone portion. Therefore, the thickness t of the mold space does not change. The side dam block 4-1 is attached separately from the side dam block 4-2 with bolts or the like (not shown), and a thin heat insulating material may be inserted between them.

型１とこすれて損傷を受けることはない。When changing the width, the carriage 13 is moved in the width direction of the slab by the hydraulic cylinder 12, and the position of the side dam block 4 is adjusted in the width direction of the slab. Since the upper and lower surfaces of the side dam block 4 are flat, even if the width is changed during casting, the side dam block 4 will not be damaged by rubbing against the block mold 1.

は勿論である。In addition, in the embodiment of the present invention, the case where the side dam blocks are connected by a spring has been described, but it is noted that the spring may not be used as long as it is an elastic body, and various other changes may be made without departing from the gist of the present invention. Of course, you can get it.

得る。[Effects of the Invention] According to the endless track type continuous casting machine of the present invention, no gap is created between the side dam block and the block mold due to thermal expansion, so that the molten metal flows between the side dam block and the pro-v.
The side dam block does not enter the contact area of the mold, preventing the occurrence of flash, and the contact area of the side dam block with the block mold remains flat as a whole even when thermally expanded, so the width can be changed during casting. Even if the dam block is damaged by rubbing against the block mold, various excellent effects can be achieved.
