ある。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cooling and supporting device for a metal belt in a continuous casting apparatus for molten metal using a metal belt.

第３図）の３種類に分類ｙれる。In recent years, continuous casting apparatuses using metal belts have been proposed in order to improve the drawing speed in continuous casting or to improve the surface properties of slabs. These can be roughly divided into (1) those in which the molten metal is solidified on one side with one metal belt (Fig. 1), and (2) those in which the molten metal is solidified on one side between two metal belts (Fig. 2). ), (3) One metal bell I・
and k)f type (e.g. casting wheel) which is more rigid than Bell I and which solidifies molten metal in the space formed between them.
It is classified into three types (Fig. 3).

いて説明する。第４図は、ベルトとＶｆ造輪の組合せ方
式の連鋳機の例であるが、金属ベルトｑ曲のメカニズム
は他の方式でも同様である。However, in either method, it is necessary to cool the belt surface, and in many cases, cooling is performed by means of a water stream from the opposite surface of the metal heald to the surface that contacts the molten metal. At this time, the belt surface may be curved due to water pressure, causing a problem that a flat slab cannot be obtained. Curvature of the belt surface often occurs when (1) the belt strength is weak compared to the water pressure, and (2) when the static pressure of the molten metal is too small to counteract the water pressure. The phenomenon of belt curvature will be explained based on FIG. FIG. 4 shows an example of a continuous casting machine that uses a combination of a belt and a Vf wheel, but the mechanism of metal belt q bending is the same for other systems as well.

この部分の水圧のため、未凝固金属部の静圧が小さく、
また金属ベルトと凝固シェルの剛性が弱い場合には図の
如く金属ベルトが湾曲し、そのために鋳片が凹型になる
。Due to the water pressure in this part, the static pressure in the unsolidified metal part is small.
Furthermore, if the rigidity of the metal belt and the solidified shell is weak, the metal belt will curve as shown in the figure, resulting in the slab becoming concave.
本発明の目的はこの様な水圧によるベルトの湾曲を防止
する事にある。An object of the present invention is to prevent the belt from bending due to such water pressure.

Alternatively, in a continuous casting device that solidifies molten metal between a metal belt and a rigid mold, the metal belt and molten metal are cooled by a water stream from the surface opposite to the surface of the metal belt that contacts the molten metal. A cooling and supporting device for a metal belt, which also has the function of simultaneously supporting the surface of a metal belt, characterized in that it is equipped with an (electro)magnet that attracts the magnetic metal belt with magnetic force in the opposite direction to the water pressure. "Support device".
