（産業上の利用分野）
本考案は、薄板を連続鋳造する装置の改良に関
するものである。[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an improvement of an apparatus for continuously casting thin plates.
（従来の技術）
薄板を製造するに際し、従来は、スラブを熱間
圧延することにより行なつていたが、溶融金属か
ら直接数mmの厚さの薄板を連続的に鋳造できるな
らば前記熱間圧延工程が省略できる為、薄板の製
造コストの大幅な低減が可能となる。(Prior Art) Conventionally, thin plates have been produced by hot rolling slabs, but if it is possible to continuously cast thin plates several mm thick directly from molten metal, then the hot rolling method is possible. Since the rolling process can be omitted, the manufacturing cost of thin plates can be significantly reduced.
そこで、最近、連続鋳造により直接薄板を製造
する方法が種々提案されている。 Therefore, recently, various methods have been proposed for directly manufacturing thin plates by continuous casting.
例えば第５図および第６図に示すような、水冷
ロール１の端面に断熱耐火材２を配置して該水冷

げ、圧下成型ロール５により所望の厚さに圧延
し、帯状の薄板６を得る方法（特開昭58−163553
号）がある。 For example, as shown in FIGS. 5 and 6, a heat insulating refractory material 2 is disposed on the end face of the water-cooled roll 1 to prevent the molten metal 3 from adhering to and solidifying the end of the water-cooled roll 1. A method of obtaining a strip-shaped thin plate 6 by pulling up the solidified shell 4 formed in contact with the surface along the water-cooled roll 1 and rolling it to a desired thickness with a reduction forming roll 5 (Japanese Patent Laid-Open No. 58-163553)
No.).
前記した方法は高い生産性を得ることができる
点で優れた方法であるが、断熱耐火材２を水冷ロ
ール１に固定しているために以下に述べるような
欠点がある。 The method described above is an excellent method in that high productivity can be obtained, but since the heat-insulating refractory material 2 is fixed to the water-cooled roll 1, it has the following drawbacks.
凝固殻４を引き上げるべく水冷ロール１が第
５図に示すようにＡの方向に回転すると、断熱
耐火材２も同時に回転する為、該断熱耐火材２

２の一部は溶融金属３中を回転するために摩耗
し易い。従つて、これらの理由により断熱耐火
材２の寿命は非常に短かく、安定して連続操業
することが困難である。 When the water-cooled roll 1 rotates in the direction A as shown in FIG.
repeats dipping into molten metal 3. For this reason, the temperature of the heat insulating refractory material 2 changes greatly, and cracks are likely to occur due to thermal shock. Further, a part of the heat insulating refractory material 2 rotates in the molten metal 3 and is therefore easily worn out. Therefore, for these reasons, the life of the heat insulating and refractory material 2 is very short, making it difficult to operate stably and continuously.
凝固殻４の幅を変えるためには長さの異なる
水冷ロール１に取り換えなければならず、大変
手間がかかる。すなわち、生成する凝固殻４の
幅は水冷ロール１の幅と同じである為、凝固殻
４の幅を変えるためには水冷ロール１自体を、
他の長さの異なるロールに取り換える必要があ
るからである。 In order to change the width of the solidified shell 4, it is necessary to replace it with a water-cooled roll 1 of a different length, which is very time consuming. That is, the width of the solidified shell 4 to be generated is the same as the width of the water-cooled roll 1, so in order to change the width of the solidified shell 4, the water-cooled roll 1 itself must be
This is because it is necessary to replace the roll with another roll having a different length.

接することを特徴とするものである。 Therefore, in order to solve the above problems, the applicant filed a patent application in 1983 for a continuous casting method that can stably supply thin sheets with good shapes and easily change the width of the thin sheets.
The invention proposed in Japanese Patent Application No. 192875, that is, the invention proposed by the present applicant in the above-mentioned Japanese Patent Application No. 192875, consists of two lower sides of a water-cooled roll 1 whose lower part is immersed in molten metal 3, as shown in FIG. A heat insulating refractory material 2 is disposed on the surface of both ends of the lower part, and the water-cooled roll 1 is rotated with these parts cut off from the molten metal 3, and as a result of the rotation, the heat-insulating refractory material 2 is formed on the lower surface other than the cut off part and pulled up. This is characterized in that the solidified shell 4 is pressed into contact with the solidified shell 4.

本出願人が提案した前記特願昭60−192875号の
連続鋳造方法は従来の問題点を解決できる優れた
連続鋳造方法であるが、その後の実験により以下
に示す問題が内在していることが判明した。(Problems to be Solved by the Invention) The continuous casting method proposed by the present applicant in Japanese Patent Application No. 1987-192875 is an excellent continuous casting method that can solve the conventional problems. It was found that the following problem existed.
すなわち、前記断熱耐火材２は、Al2O3、
SiO2、BN、Si3N4等で構成されており、水冷ロ

下部を覆つている。この場合、断熱耐火材２は水
冷ロール１と直接ｍ，m′面で摺動している為、
断熱耐火材２と水冷ロール１は摺動面ｍ，m′で
密着させて一定の力で押圧されている。 That is, the heat insulating refractory material 2 is made of Al 2 O 3 ,
It is made of SiO 2 , BN, Si 3 N 4 , etc., and contacts the end surface of the water-cooled roll 1 to cover the lower side of the water-cooled roll 1 . In this case, since the heat insulating refractory material 2 is sliding directly on the water-cooled roll 1 on the m and m' planes,
The heat-insulating refractory material 2 and the water-cooled roll 1 are brought into close contact with each other at sliding surfaces m and m' and are pressed with a constant force.
しかして、この押圧力が大きすぎると、断熱耐
火材２は押圧力と水冷ロール１との摩擦力の作用
によつて亀裂が生じたり、また先端の角が欠け易
くなる。これより断熱耐火材２の寿命は大変短く
なり、安定して連続操業することが困難となる。 However, if this pressing force is too large, the heat insulating refractory material 2 is likely to crack due to the effect of the pressing force and the frictional force with the water-cooled roll 1, and the corners of the tip are likely to be chipped. As a result, the life of the heat insulating refractory material 2 becomes very short, making it difficult to operate stably and continuously.
また、押圧力が小さすぎると、水冷ロール１と
断熱耐火材２の間に〓間が出来、該〓間に溶融金
属３が侵入して凝固殻４の端部形状が悪化した
り、凝固殻４が破れ易くなる。 In addition, if the pressing force is too small, a gap will be created between the water-cooled roll 1 and the heat insulating refractory material 2, and the molten metal 3 will enter the gap, causing the end shape of the solidified shell 4 to deteriorate or 4 becomes easy to tear.
すなわち、本出願人が先に提案した連続鋳造方
法にあつては前記断熱耐火材２の水冷ロール１へ
の押圧力の調整が困難であり、安定した操業が難
しかつた。 That is, in the continuous casting method previously proposed by the present applicant, it was difficult to adjust the pressing force of the heat insulating refractory material 2 against the water-cooled roll 1, making stable operation difficult.
