Regarding machines.
従来のベルト式連続鋳造装置には、第１，２図
に示すようなものがある。 BACKGROUND ART Conventional belt-type continuous casting apparatuses include those shown in FIGS. 1 and 2.
第１図は鋳片の長辺に垂直な縦断面図、第２図
は第１図のＦ−Ｆ矢視図である。 FIG. 1 is a vertical cross-sectional view perpendicular to the long side of the slab, and FIG. 2 is a view taken along the line FF in FIG. 1.

の押えブロツク（固定されている）である。 In Figures 1 and 2, 1 is the slab, and 1' is the slab 1.
The upper surface (molten steel, i.e. meniscus), 2 is a belt (generally made of steel with a thickness of 1 to 2 mm), 3 is a pulley to which belt 2 is applied and driven, 3' is a pinch roller for drawing the slab 1, 4 is a The tundish, 5 is a nozzle that supplies the molten steel in the tundish 4 between the belts 2, 6 is the molten steel pressure between the belts 2 (there is molten steel 1' between the belts 2, so it corresponds to the height of the molten steel 1') 7 is a spray nozzle, 8 is a spray nozzle that supports the back-up roll (pressure is applied to the belt 2), and 8 is a cooling water sprayed from the nozzle 7 (sprayed onto the back of the belt 2, cooling the belt 2 and indirectly spraying the slab 1). 9 is a fixed side block (prevents the molten steel 1' from escaping laterally); 10 is a cooling water passage (cooling the side block 9); Slab 1
), 11 is the belt 2
This is a presser foot block (fixed).
以上のベルト式連続鋳造装置は、第１図中の矢
印方向にベルト２を注湯量に合わせて動かし、溶
鋼を凝固させて鋳片１を製造する。 The belt-type continuous casting apparatus described above moves the belt 2 in the direction of the arrow in FIG. 1 in accordance with the amount of poured metal to solidify the molten steel and produce the slab 1.
しかしながら、この装置においては、第３図，
第４図に示すような欠点がある。 However, in this device, as shown in FIG.
There are drawbacks as shown in FIG.
第３図は鋳込操業状態を示す。サイドブロツク
９は溶鋼に接する側が約300℃まで温度が上り、
膨張し、コーナー部Ｃのみがベルト２と接し、摩
耗する。 Figure 3 shows the casting operation status. The temperature of side block 9 on the side in contact with the molten steel rises to approximately 300℃.
It expands, and only the corner portion C comes into contact with the belt 2, causing wear.
第４図は鋳込操業終了後の状態を示す。コーナ
ー部Ｃは摩耗により肉厚が薄くなり、鋳込中は約
300℃の温度であつたのが常温まで冷えるので、
ベルト２と接触せず、隙間Ｄを生じる。この隙間
Ｄは0.2〜0.5mmのオーダーである。 Figure 4 shows the state after the casting operation is completed. The wall thickness of corner C becomes thinner due to wear, and during casting it becomes approximately
Since the temperature of 300℃ cools down to room temperature,
It does not come into contact with the belt 2, creating a gap D. This gap D is on the order of 0.2 to 0.5 mm.
次に、鋳込操業を行うと、この隙間Ｄに溶鋼が
差し込み、パリとなり、下方に引き抜かれるの
で、引抜抵抗の増大、バリによるサイドブロツク
の損傷、バリにより鋳片の収縮が拘束されるので
表面ワレが発生する等の好ましくない現象が生じ
る。 Next, when a casting operation is performed, molten steel is inserted into this gap D, becomes burr, and is pulled out downward, which increases the drawing resistance, damages the side block due to burrs, and restricts the shrinkage of the slab due to burrs. Unfavorable phenomena such as surface cracking occur.
このように、くりかえし使用により、鋳込操業
がやりにくくなり、成品品質も悪くなるという欠
点がある。 As described above, repeated use makes the casting operation difficult and the quality of the finished product deteriorates.
本発明は、上記の欠点を解消するためになされ

ことを特徴とするベルト式連続鋳造機に関するも
のである。 The present invention has been made in order to eliminate the above-mentioned drawbacks, and in order to ensure the contact between the belt and the molten metal side corner part of the side block in a belt type continuous casting machine, the corner part of the side block The present invention relates to a belt-type continuous casting machine characterized in that adjacent opposing belt portions can be pressed by pressing means whose pressing force can be adjusted.
第５図、第６図に本発明の実施態様例を示す。 Embodiments of the present invention are shown in FIGS. 5 and 6.
第５図、第６図は、サイドブロツク９の溶鋼側
コーナ部Ｃとベルト２との接触を確実にするため
にコーナ押え１２，１２−ａを設けた例を示して
いる。 5 and 6 show an example in which corner pressers 12, 12-a are provided to ensure the contact between the molten steel side corner C of the side block 9 and the belt 2.
第５図の例では、コーナ押え１２により、ベル

触する。また、第６図のように、コーナ押え１２
−ａをコーナ部Ｃ側へ若干移動させたものを用い
ると、ベルト２はより確実にサイドブロツク９の
コーナ部Ｃと接する。 In the example shown in FIG. 5, the corner presser 12 ensures that the belt 2 contacts the corner C of the side block 9. Also, as shown in Fig. 6, the corner presser 12
If -a is slightly moved toward the corner C side, the belt 2 will contact the corner C of the side block 9 more reliably.
コーナ押え１２，１２−ａのベルト２への押し
付け力の調節は、第５図、第６図の力Ｆの調節に
より行う。 The pressing force of the corner pressers 12, 12-a against the belt 2 is adjusted by adjusting the force F shown in FIGS. 5 and 6.
以上のように、本発明では、ベルトとサイドブ
ロツクのコーナ部とが常に接触しているため、溶
湯が差し込まず、バリが発生しないので、操業が
安定し、成品品質も良好なものが得られる。 As described above, in the present invention, since the belt and the corner of the side block are always in contact with each other, molten metal does not get inserted and burrs do not occur, resulting in stable operation and good product quality. .
本発明は溶鋼のみでなく、他の溶融金属の連鋳
にも適用できる。 The present invention is applicable not only to molten steel but also to continuous casting of other molten metals.
