本発明は、冷却ドラムの周面を常に均質で平滑な状憔に
維持しながら金属薄帯を製造するツインドラム方式の連
続鋳造装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a twin-drum type continuous casting apparatus that manufactures metal ribbon while always maintaining the peripheral surface of a cooling drum in a homogeneous and smooth state.
最近、溶鋼等の溶融金属から最終形状に近い敢闘程度の
厚みをもつ金属薄帯を直接的に製造する方法が注目され
ている。この連続鋳造方法によるとき、従来のような加
工率の大きな熱延工程を必要とすることなく、また最終
形状にする圧延も軽度のもので済むため、工程及び設備
の簡略化が図られる。BACKGROUND ART Recently, a method of directly manufacturing a metal ribbon having a thickness close to the final shape from molten metal such as molten steel has been attracting attention. When this continuous casting method is used, there is no need for a hot rolling process with a large processing rate as in the conventional method, and only light rolling is required to form the final shape, so the process and equipment can be simplified.
このような連続鋳造方法の一つとして、ツインドラム方
式がある（特開昭６０−１３７５６２号公報参照）。One such continuous casting method is the twin drum method (see Japanese Patent Laid-Open No. 137562/1983).
この方式においては、互いに逆方向に回転する一対の冷
却ドラムを水平に配置し、その一対の冷却ドラムの局面
及び必要に応じてサイド堰で仕切られた湯溜り部に供給
された溶融金属を冷却ドラムの周面で冷却・凝固するこ
とによって、凝固シェルを生成している。それぞれの冷
却ドラムの周面で生成した凝固シェルは、冷却ドラムの
回転に伴ってドラムギャップ部に移動する過程で、圧接
・一体化され、金属薄帯として送り出される。In this method, a pair of cooling drums that rotate in opposite directions are arranged horizontally, and the molten metal supplied to the surface of the pair of cooling drums and, if necessary, a sump separated by a side weir is cooled. A solidified shell is generated by cooling and solidifying on the peripheral surface of the drum. The solidified shells generated on the circumferential surface of each cooling drum are pressed and integrated in the process of moving to the drum gap portion as the cooling drum rotates, and are sent out as a metal ribbon.
このようにして製造される金属薄帯は、その表面性状が
冷却ドラムの表面状態に大きく影響される。たとえば、
凝固初期において、幅方向に不均一凝固があると、凝固
シェルの成長過程における熱収縮によって縦割れが金属
薄帯に発生し易くなる。この不均一凝固を促進するもの
としては、冷却ドラムの周面に付着する酸化物がある。The surface quality of the metal ribbon manufactured in this way is greatly influenced by the surface condition of the cooling drum. for example,
If there is nonuniform solidification in the width direction at the early stage of solidification, longitudinal cracks are likely to occur in the metal ribbon due to thermal contraction during the growth process of the solidified shell. This non-uniform solidification is promoted by oxides that adhere to the circumferential surface of the cooling drum.
すなわち、付着した酸化物は、冷却ドラムの抜熱作用を
低下させるものであり、しかも冷却ドラムの周面に局部
的且つ不規則に付着する。また、鋳造中に生じた冷却ド
ラム周面の局部的な損傷も、不均一凝固を助長するもの
である。That is, the attached oxide reduces the heat removal effect of the cooling drum, and moreover, it adheres locally and irregularly to the circumferential surface of the cooling drum. In addition, local damage to the circumferential surface of the cooling drum that occurs during casting also promotes uneven solidification.
そこで、冷却効果のバラツキを解消するため、実願昭５
９−２１６８６６号（実開昭６０−１３６８４９号公報
）で、冷却ドラムの表面をブラッシングによって清浄に
することを提案した。Therefore, in order to eliminate the variation in cooling effect,
No. 9-216866 (Japanese Utility Model Publication No. 60-136849) proposed cleaning the surface of the cooling drum by brushing.
しかし、ブラッシングによる場合、冷却ドラムの表面性
状をドラム軸方向に関して均一に維持することが難しい
。すなわち、ブラシは多数の硬質ワイヤで構成されてお
り、この硬質ワイヤの長さを精度良く仕上げることや、
硬質ワイヤの植込み密度を均一化することが困難であり
、このようなバラツキのあるブラシで冷却ドラムの周面
をブラッシングするとき、処理された後の周面が均一な
ものとなることは期し難い。また、ブラシを長時間使用
するとき、ブラシのへクリ等が生じ、清浄作用の不均一
化がより大きなものとなる。However, when brushing is used, it is difficult to maintain the surface quality of the cooling drum uniform in the drum axial direction. In other words, the brush is made up of a large number of hard wires, and the length of these hard wires can be finished with high precision.
It is difficult to equalize the implantation density of hard wires, and when brushing the circumferential surface of the cooling drum with such uneven brushes, it is difficult to expect that the circumferential surface will be uniform after being treated. . Furthermore, when the brush is used for a long period of time, the brush may become dented and the cleaning effect becomes more uneven.
また、冷却ドラムの周面を砥石で研削しながら鋳造を行
う方法も提案されている。しかし、この砥石による研削
の場合には、冷却ドラムの幅方向に一体物となった砥石
を製作することが困難な上に、異物の噛込みによる砥石
の欠損、冷却ドラムのプロフィールに対する砥石の追従
性等に問題がある。A method has also been proposed in which casting is performed while grinding the peripheral surface of the cooling drum with a grindstone. However, in the case of grinding using this grinding wheel, it is difficult to manufacture a grinding wheel that is integrated in the width direction of the cooling drum, and the grinding wheel may be damaged due to biting of foreign objects, and the grinding wheel may not follow the profile of the cooling drum. There is a problem with gender etc.
他方、冷却ドラムの周面に断熱材を塗布してその抜熱能
力を調整しようとする場合、基地の周面に残留している
酸化物又は断熱材等のために、塗布された断熱材にムラ
が生じ、依然として抜熱作用が不規則なものとなる。On the other hand, when trying to adjust the heat removal capacity by applying a heat insulating material to the circumferential surface of the cooling drum, the applied heat insulating material may be Unevenness occurs, and the heat removal effect remains irregular.
そこで、本発明は、この冷却ドラムの周面に付着する酸
化物等や周面に生じた損傷等の影響を抑、制して、均一
な条件下で品質の安定した金属薄帯を製造することを目
的とする。Therefore, the present invention suppresses and controls the effects of oxides adhering to the circumferential surface of the cooling drum and damage caused to the circumferential surface, and produces a metal ribbon of stable quality under uniform conditions. The purpose is to

ベルトを押し付けたことを特徴とする。In order to achieve this purpose, the twin-drum continuous casting apparatus of the present invention has a pair of rotatable cooling drums that form a pool for rapidly solidifying the supplied molten metal and casting a metal ribbon. It is characterized in that a sand belt that is arranged parallel to each other and is continuously supplied is pressed against the circumferential surface of the cooling drum on the side opposite to the water pool.

This sand belt 11 can move or reciprocate between the pair of drums 3a and 13b, and has a width corresponding to at least the length of the water reservoir 3 along the axial direction of the cooling drums la and lbO. As the sand belt 11, a cloth belt or the like to which abrasive grains of #80 to #280 are glued is used.

た耐熱ゴム等の表面層をもつことが好ましい。During pressing, the roll 12 is pressed against the circumferential surface of the cooling drums la, lb by a cylinder 14 with a predetermined force. For this pressing, it is preferable that the roll 12 has a surface layer made of highly flexible heat-resistant rubber or the like so as to bring the sand belt 11 into close contact with the circumferential surface of the cooling drums la, lb.

周面に対して、ノズル１５から断熱材を吹き付ける。Therefore, at least the circumferential surfaces of the cooling drums la, lb that partition the water reservoir 3 are always in a state where the sand belt 11 is pressed. Therefore, when the sand belt 11 is pressed, there is no adhesion of oxides, heat insulating materials, etc. to the circumferential surfaces of the cooling drums la, lb that have passed through the position.
It remains uniform and clean along the axial direction. A heat insulating material is sprayed onto this peripheral surface from a nozzle 15.

呈するものである。As shown in FIG. 2, the nozzle 15 is connected to a cooling drum la,
A plurality of nozzle holes are provided in the axial direction of the cooling drums la and lb, and the heat insulating material can be sprayed uniformly in the axial direction of the cooling drums la and lb. At this time, since the circumferential surfaces of the cooling drums la, lb are made uniform by the sand bell [1], the sprayed heat insulating material adheres uniformly to the circumferential surfaces of the cooling drums la, lb. MgO, WC, etc. are used as the heat insulating material. This heat insulating material adjusts the heat removal capacity of the cooling drums la and lb, and
This has the effect of relaxing and uniformizing the cooling conditions for molten metal.

方向に関して均一に成長する。The heat insulating material applied to the circumferential surface of the cooling drums la and lb is
It is desirable that the cooling drums la, lb have wall thicknesses of - in the axial direction. As a result, on the circumferential surfaces of the cooling drums la and lb that enter the sump 3, a homogeneous heat insulating layer is formed in the axial direction. Therefore, variations in the heat removal capacity of the cooling drums la, lb are suppressed, and the solidified shell grows uniformly in the axial direction of the cooling drums la, lb.

Pressing 1. Therefore, the sand belt 11 can follow the peripheral surface profile of the cooling drums la and lb well, and can withstand a certain degree of foreign matter getting caught. Furthermore, since the sand belt 11 is used while moving its working surface, uniform grinding is ensured over a long period of time. This point is fundamentally different from conventional grinding using a whetstone or polishing using wire brushing.
