状を悪化させる。<Prior Art> Conventionally, as shown in FIGS. 3(a) and 3(b), as an apparatus for continuously casting a thin ribbon 4 from molten metal such as molten steel, a pair of adjacent axes whose axes are parallel to each other is used. cooling roll 1
．． 1' and the pair of cooling rolls 1°1' are shown in FIG. 3(a).
As shown by the arrows, a drive means (not shown) for rotating at the same circumferential speed in opposite directions is pressed against each end of a pair of cooling rolls 1.1', and the molten metal is poured from the pouring nozzle 2. A device is known which consists of a pair of side guides 3.3' for feeding metal 5 and forming a molten metal pool. (For example, see Japanese Patent Application Laid-Open No. 60-30556.) <Problems to be Solved by the Invention> The above-described continuous ribbon casting apparatus has the following drawbacks. That is, the solidified shell formed and adhered to the inner surface of the fixed side guide 3゜3' gets into the space between the cooling rolls 1.1', resulting in abnormal pressure reduction, causing problems such as plate breakage,
Sliding wear between the fixed side guide 3°3' and the end face of the cooling roll 1.1', axial vibration and backlash of the cooling rolls 1.1' cause molten metal to flow into the cooling roll 1.1'. The cooling roll 1°1'
This impedes the smooth rotation of the ribbon and deteriorates the shape of the end of the manufactured ribbon.

くバブリングし、湯溜り部が不安定となる。On the other hand, Japanese Unexamined Patent Publication No. 62-77152 proposes a method in which an inert gas is blown into a gap between a side dam made of a refractory material constituting a pool and an end face of the roll. This method is characterized by blowing inert gas through the porous refractories of the side guides while maintaining a small gap, so if casting is performed for a long time, the required gap may be maintained due to refractory melting etc. is impossible, and it is necessary to blow out a large amount of high-pressure gas to prevent the molten metal from flowing out. In this case, the inert gas causes the molten metal in the pool to bubble violently, making the pool unstable.
数ｌｌ１ｌ厚以下の薄帯を鋳造する場合、湯溜り高さは
高くないため、上記方式では安定して薄帯を製造するこ
とは難しく、ブレークアウト等のトラブルが発生しやす
い。When casting a thin strip having a thickness of several 111 l or less, since the pool height is not high, it is difficult to stably produce the thin strip using the above method, and troubles such as breakouts are likely to occur.

製造する場合に端辺における凝固生成物の付着を免れ得
ず、薄帯の端部性状悪化やブレークアウトが生じ易かっ
たため、工業的に連続して鋳込みを行うことは事実上不
可能であった。As mentioned above, with conventional means, when producing a rapidly cooled ribbon with a thickness of several meters or less, it was impossible to avoid the adhesion of solidification products at the edges, and deterioration of the edge properties of the ribbon and breakout were likely to occur. It was virtually impossible to carry out continuous casting on an industrial scale.

接触面を溶湯の融点近くまで加熱保持しないかぎり、凝
固シェルの生成は防止できず、特に溶湯が鉄合金のよう
な高融点金属の場合、冷却ロール端面と接触するためサ
イドダムをかかる高温まで加熱するのは不可能である。(1) Conventional means of sealing the end face side of the roll gap with ceramic side dams cannot prevent the formation of a solidified shell unless the contact surface of the side dam member with the molten metal is heated and maintained close to the melting point of the molten metal. If the side dam is made of a high melting point metal such as an iron alloy, it is impossible to heat the side dam to such a high temperature because it comes into contact with the end face of the cooling roll.
なお隙間をあけて、ガスを吹き出す場合も同様である。The same applies to the case where a gap is opened and the gas is blown out.
（２）冷却ロールキス部出側で端部形状の良好な薄板を
製造するためには、サイドダムで生成した凝固シェルが
容易に脱落し、その周期が非常に短いことが条件となり
、熱伝導のよい金属製端辺が適している。(2) In order to produce a thin plate with a good end shape on the exit side of the cooling roll kissing part, it is necessary that the solidified shell generated at the side dam falls off easily and that the cycle is very short, and that it has good heat conduction. Metal edges are suitable.
（３）上記サイドダムとして金属端辺を使用した場合、
ロール端面とサイドダムの摺動面の隙間に溶鋼が差し込
みやすく、容易に鋳ぼり（凝固シェル）を生成して、ロ
ール端面とサイドダム間の隙間が大きくなりやすい。(3) When using metal edges as the above side dam,
Molten steel easily enters the gap between the roll end face and the sliding surface of the side dam, easily forming a casting shell (solidified shell), and the gap between the roll end face and the side dam tends to become large.
