［産業上の利用分野］
本発明は帯板を連続的に鋳造するための双ロール式連鋳
機に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a twin-roll continuous casting machine for continuously casting strips.
［従来の技術］
溶湯より帯板を製造する手段としてはスラブ圧延方法が
一般的であるが、近年溶湯より直接帯板を鋳造し得る双
ロール式の帯板連鋳機が発案されるに至っている。[Prior Art] Slab rolling is a common method for producing strips from molten metal, but in recent years a twin-roll continuous strip caster has been proposed that can directly cast strips from molten metal. There is.
該双ロール式連鋳機は第４図に示すように、ロール内面
を水等で冷却できるようにした一対の冷却ロールａを、
鋳造しようとする帯板すの厚さに対応した間隙Ｇに保っ
て平行に配置し、該間隙Ｇに溶湯Ｃを導き、両ロールａ
を回転させつつ間隙Ｇより帯板すを連続的に鍔出するも
のである。As shown in Fig. 4, this twin-roll continuous casting machine has a pair of cooling rolls a whose inner surfaces can be cooled with water or the like.
They are arranged in parallel with a gap G corresponding to the thickness of the strip to be cast, the molten metal C is guided into the gap G, and both rolls a
The strip is continuously flung out from the gap G while rotating.
Ｃ発明が解決しようとする問題点］
しかし、該一対の冷却ロールａは溶湯Ｃと接触する面が
、溶湯Ｃからの熱を受けて熱膨張するが、内部は冷却さ
れるので全体として太鼓状に変形し、帯板すの幅方向の
板厚分布は、両端部に比べ中央部が薄くなってしまう。[Problems to be Solved by the Invention C] However, the surfaces of the pair of cooling rolls a that come into contact with the molten metal C receive heat from the molten metal C and thermally expand, but the inside is cooled, so the overall shape is drum-shaped. As a result, the thickness distribution in the width direction of the strip plate becomes thinner at the center than at both ends.
この帯板すの幅方向の板厚不均一を、後工程の圧延工程
で矯正することは容易でなく生産性が低下する。It is not easy to correct this non-uniform thickness in the width direction of the strip in the subsequent rolling process, resulting in a decrease in productivity.
この対策として冷却ロールａの中央部の径を、予想され
る熱膨張分小さくすることが考えられるが、鋳造条件の
変動に対応できず、帯板すの幅方向の板厚を充分に制御
することが望めない。As a countermeasure to this problem, it is possible to reduce the diameter of the central part of the cooling roll a by the amount of expected thermal expansion, but this cannot cope with fluctuations in casting conditions, and it is difficult to sufficiently control the thickness of the strip in the width direction. I can't hope for that.
［問題点を解決するための手段］

鋳機にかかるものである。[Means for Solving the Problems] The present invention solves the above-mentioned problems, and makes it possible to arbitrarily control the casting surface of the cooling roll from concave to convex stripes, and to adjust the thickness of the strip in the width direction. A hollow cylindrical cooling sleeve is fluid-tightly fitted and fixed to the shaft, and an expansion and contraction device is provided to move the cast surface of the cooling sleeve into the cavity of the cooling sleeve. The present invention relates to a twin-roll type continuous casting machine characterized in that a plurality of cooling rolls are attached in a radial manner to constitute a cooling roll, and the pair of cooling rolls are arranged so as to be rotatable with a required gap.
［作 用コ
冷却スリーブの鋳造面を拡縮装置により、例えば内側に
移動させることにより冷却ロールのプロフィルが凹状に
変形し、又外側に移動することにより冷却ロールのプロ
フィルが凸状に変形する。[Function] By moving the casting surface of the cooling sleeve inward, for example, by an expanding/contracting device, the profile of the cooling roll is deformed into a concave shape, and by moving it outward, the profile of the cooling roll is deformed into a convex shape.
［実 施 例］ 以下、本発明の実施例を図面を参照しつつ説明する。[Example] Embodiments of the present invention will be described below with reference to the drawings.
第１図乃至第３図は本発明の一実施例であり、駆動用モ

内部が空洞の冷却スリーブ２を該冷却スリーブ２の側板
３の中心において嵌装し、液密に固定する。1 to 3 show an embodiment of the present invention, in which a cooling sleeve 2 having a cylindrical shape and a hollow interior is attached to a shaft 1 connected to a drive motor via a speed reducer and a side plate 3 of the cooling sleeve 2. Fit in the center and fix in a liquid-tight manner.

着位置は冷却スリーブ２の幅方向略中央部となる。A plurality of (eight in this embodiment) fluid pressure cylinders 5 are fixed at the end of a cylindrical body 6 in a radial manner at approximately equal intervals in the center of the cavity 4 of the shaft l, and the pistons of the multi-fluid pressure cylinders 5 The tip of the rod 6 is fixed to the back side of the casting surface 7 of the cooling sleeve 2. Here, the fixed position of the piston rod 6 is approximately at the center of the cooling sleeve 2 in the width direction.
前記各流体圧シリンダ５の流体給排管８，９を、一方の
側板３に液密に貫通させ、冷却スリーブ２の外側におい
て開閉可能に夫々閉止しである。The fluid supply and discharge pipes 8 and 9 of each of the fluid pressure cylinders 5 are made to penetrate through one side plate 3 in a fluid-tight manner, and are respectively closed so as to be openable and closable outside the cooling sleeve 2.

The cooling rolls 10 are disposed with a gap G such that a molten metal pool 11 is formed above between the cooling rolls 10.

排管８，９を閉止する。With the above configuration, the amount of concave deformation of the cooling sleeve 2 is calculated based on conditions such as the type of molten metal to be cast, the thermal load such as temperature, and the size of the gap G. The piston rod 6 is drawn in by supplying and discharging fluid through the fluid supply and discharge pipe 8.9, and the casting surface 7 of the cooling sleeve 2 is
is deformed into a concave shape in the axial direction as shown by the two-dot chain line in FIG. Therefore, the piston rod 6 is stopped at a position where the casting surface 7 has a desired amount of deformation, and the fluid supply and discharge pipes 8 and 9 are closed.

な帯板１２が連続的に鍔出される。When continuous casting is performed using the cooling rolls 10 and 10 set in this manner, the cooling sleeve 2 receives heat from the molten metal and thermally expands, eliminating the pre-formed recesses and forming a flat casting surface 7 with no irregularities. is formed, and a strip plate 12 having a uniform thickness in the width direction is continuously flanged.
このように、前記冷却スリーブ２の鋳造面７を凹状ばか

能となる。In this way, the casting surface 7 of the cooling sleeve 2 can be deformed not only into a concave shape but also into a convex shape.
It becomes possible to arbitrarily control the outer diameter profile in the axial direction.

いて種々変更を加え得ることは勿論である。Note that the twin roll continuous casting machine of the present invention is not limited to the above-described embodiment, but the casting surface of the cooling sleeve is made concave in advance, and the lack of expansion due to heat from the molten metal is compensated for by the protrusion of the piston rod. Of course, various changes may be made without departing from the gist of the present invention, such as making the casting surface flat.
