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

ルト2の押えブロック(固定されている)である。In Figure 1.2, 1 is the slab, and 1' is the upper surface of the slab 1 (
molten steel, i.e. meniscus), 2 is a belt (generally 1
~2+o+t steel), 3 is a gooley driven by a belt 2, 3' is a vinyl roll for drawing the slab 1, 4
5 is a nozzle that supplies the molten steel in the tundish 4 between the belts 2, and 6 is the molten steel pressure between the belts 2 (
7 is a spray nozzle; 8 is the nozzle 7;
9 is sprayed cooling water (sprayed on the back side of the belt 2, cools the belt 2 and indirectly cools the slab 1, and solidifies the molten steel 1't). A fixed side block (prevents the molten steel 1' from escaping laterally), 10 a cooling water passage (cools the side block 9 and indirectly cools the side of the slab 1), 11 a 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。However, in this device, FIG.
第4図に示すような欠点がある。There are drawbacks as shown in FIG.
第3図は鋳込操業状態を示す。サイドブロック9は溶鋼
に接する側が約300℃まで温度が上り、膨張し、コー
ナ一部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 the side block 9 in contact with molten steel rises to about 300° C., expands, and only a portion C of the corner contacts the belt 2, causing wear.
第4図は鋳込操業終了後の状態を示す。コーナ一部Cは
摩耗により肉厚が薄くなり、鋳込中は約300℃の温度
でめったのが常温まで冷えるので、ベルト2と接触せず
、隙間Di生じる。Figure 4 shows the state after the casting operation is completed. The wall thickness of the corner part C becomes thinner due to abrasion, and the temperature is about 300° C. during casting, but since it rarely cools down to room temperature, it does not come into contact with the belt 2, and a gap Di is created.
この隙間りは[L2〜[15mのオーダーである。This gap is on the order of [L2 to [15 m].
次に、鋳込操業を行うと、この隙間りに溶鋼が差し込み
、パリとなり、下方に引き抜かれるので、引抜抵抗の増
大、パリによるサイドブロックの損傷、パリにより鋳片
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, forms a flash, and is pulled out downward, increasing the drawing resistance, damaging the side block due to the flash, and restricting shrinkage of the slab due to the flash. Unfavorable phenomena such as surface cracking occur.
このように、〈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たもので

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 was 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 of the side block in a belt type continuous casting machine,
Either the side block has a dedicated means for pressing the opposite belt part near the corner part, or the corner part of the side block has a thicker wall thickness, or the side block has the means and the wall thickness is thicker. The present invention relates to a belt type continuous casting machine characterized by the following.
第5図、第6図、第7図に本発明の笑施態様例を示す。Embodiments of the present invention are shown in FIGS. 5, 6, and 7.
第5図、第6図は、サイドブロック9の溶鋼側コーナ部
Oとベルト2との接触を確実にするためにコーナ押え1
2.12−aを設けた例を示している。5 and 6 show a corner presser 1 to ensure contact between the molten steel side corner O of the side block 9 and the belt 2.
2.12-a is shown.
第7図は、サイドブロック9のコーナ部Cの肉厚を厚く
した例を示している。FIG. 7 shows an example in which the wall thickness of the corner portion C of the side block 9 is increased.
第5図の例では、コーナ押え12により、ベルト2はサ
イドブロック9のコーナ部Oと確実に接触する。また、
第6図のように、コーナ押え12−aをコーナ部O側へ
若干移動させたものを用いると、ベルト2はエフ確実に
サイドブロック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 O of the side block 9. Also,
If the corner presser 12-a is moved slightly toward the corner O side as shown in FIG. 6, the belt 2 will surely come into contact with the corner C of the side block 9.
更に、第7図のようにコーナ部Cの肉厚を厚くすること
にエフ、コーナ押え12ある9は12−aによるベルト
押し付は効果が増す(なお、第7図にはコーナ押えを図
示していない)。Furthermore, as shown in Fig. 7, increasing the wall thickness of the corner portion C increases the effect of pressing the belt with the corner presser 12 (9) 12-a (note that the corner presser is not shown in Fig. 7). (not shown).
−z−す押え12.12−aのベルト2への押し付は力
の調節は、第5図、給6図の力Fの調節により行う。-z- The force for pressing the presser foot 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ックの
コーナ部とが常に接触しているため、溶湯が差し込まず
、パ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 no flaking occurs, resulting in stable operation and good product quality. .
本発明は溶銅のみでなく、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 copper but also to continuous casting of other molten metals.
