である。[Prior Art] 1 In a block-type continuous casting equipment, cooling blocks 1 are connected in an endless chain as shown in FIG. A mold is constructed by arranging the cooling block chain 2 so as to circulate so as to form a mold, and disposing the cooling block chain 2 so that the target line walls 3 face each other, and the cooling block 1 is arranged in synchronization with the drawing speed of the slab 4. The cooling block 1 is made to circulate while gradually growing a shell on the surface of the cooling block 1.

能である。[Problems to be solved by the invention] In such block-type continuous casting equipment, the mold width is usually about 1 m to 1.5 m, and therefore the cooling block constituting the mold has a widthwise width smaller than its cross-sectional area. becomes significantly longer. In addition, since the inner surface of the cooling block comes into contact with high-temperature hot water, an extremely large thermal gradient occurs between it and the outer surface, and due to this thermal distortion, the cooling block warps several tens of centimeters at both ends, making it difficult to function as a mold. This has led to a situation in which the situation does not occur. Furthermore, since the thermal stress greatly exceeds the yield point, large permanent deformation remains and repeated use is impossible.
本発明は、上記実情に鑑み実用に足る鋳型を提供しよう
とするものである。In view of the above circumstances, the present invention aims to provide a mold that is suitable for practical use.

に密着さＩたことを特徴どするものである。[Means for Solving the Problems] The present invention provides a block-type continuous casting machine constructed by arranging cooling block chains in which one cooling block is connected to the end of the shaft, and the cooling block chains are hung around a guide wheel, facing each other. The mold is characterized in that the cooling block is divided as required in the width direction, and each divided cooling block piece is closely attached so as to be separable.
［作 川］
冷却ブロックｊ１の溶湯接触面は自由に膨張でき、膨張

ブロック片は熱変形を生じることがない。[Sakukawa] The molten metal contact surface of the cooling block j1 can freely expand, and the expansion is absorbed by the separation of the cooling block pieces, so the cooling block pieces do not undergo thermal deformation.
［実 施 例］ 以下図面に基づき本発明の詳細な説明する。[Example] The present invention will be described in detail below based on the drawings.

実施例では冷却ブロック１を幅方向に複数分割しである
。The cooling block 1 is shown in d) in FIGS. 1 and 2, and in this embodiment, the cooling block 1 is divided into a plurality of parts in the width direction.

要数連設し、その両端に押え片８を配設する。As shown in FIG. 3, the molten metal contacting surface 6 side of the block piece 5 is widened in the width direction and the circumferential direction, and an escape gap is formed on the opposite side. Therefore, the end faces of the cooling block pieces 5 in the width direction and circumferential direction on the molten metal side reliably contact the adjacent block pieces. A through hole 5 is made in the cooling block piece 5, and a bushing 7 is inserted 1J'' in it.A required number of cooling block pieces 5 are arranged in a row in the width direction, and presser pieces 8 are arranged at both ends thereof.

両端に固定ナツトを螺着する。A through hole is formed in the holding piece 8 at the same position as the cooling block piece 5, and a bushing 9 is inserted into the hole. Further, a presser plate 10 is disposed on both sides of the presser piece 8, and the presser plate 10, the presser piece 8, and the cooling block 1 are fitted with a guide rod 11. The guide rod 11 has a holding piece 8 and a bushing 7.9 on the cooling block 1.
It is fitted through and is slidable in the axial direction. A presser plate 10 is attached to both ends of the guide rod 11 by screwing nuts 1 to 12.
A compression spring 13 is interposed between the holding piece 8 and the holding plate 10, and the holding piece 8 and the cooling block 5 are brought into close contact with each other. Further, U-shaped grooves 14 and 15 are bored on the anti-molten metal side of the cooling block piece 5 and the holding piece 8, and the U-shaped groove 14.
15, and fit the shaft 16 into the shaft 15, and pass both ends of the shaft 16 through the holding plate 10, and the shaft 16
Screw the fixing nuts on both ends.

る。When the cooling I/O disk 1 having the above structure comes into contact with molten metal, the contact surface 6 side thermally expands. There is no way to restrain the cooling block pieces 5 from each other, and when thermal expansion occurs, each cooling block piece 5,
The holding piece 8 overcomes the pressing force of the compression spring 13 and relatively moves in the width direction by the amount of thermal expansion. That is, although the gap on the side of the opposite contact surface becomes larger, no warping occurs, the flatness of the contact surface 6 is maintained, and the compression spring 13 guarantees its adhesion.

でき永久歪が残ることもない。Since the contact surface side of the cooling block piece 5 can freely expand and contract in response to thermal changes, generation of large thermal stress can be prevented and no permanent distortion will remain.
而して、冷却ブロック１は繰返し使用が可能となる。Thus, the cooling block 1 can be used repeatedly.
尚、冷却ブロック片相互の接触面側の密着性が確保でき
れば、反接触面側の逃げは必り゛しも必要でない。Incidentally, as long as the adhesion between the cooling block pieces on the contact surface side can be ensured, relief on the non-contact surface side is not necessarily required.
