PURPOSE:To prevent solidified adhesion of molten steel to side seals and to stably produce a thin slab by using the specific means at the time of continuously casting the thin slab by rotating a water cooled mold providing the side seals at both sides in the molten steel. CONSTITUTION:In an apparatus in which the water cooled mold 2 is rotated to the arrow mark direction in the molten steel 3 in a vessel 6 and solidified shell 4 of the molten steel is formed on the surface thereof and the thin slab is produced by continuously drawing, the side seals 1 are arranged at both ends of the rotating mold 2 in order to prevent from which the slab having more than the prescribed size is formed by solidification caused by bringing the molten steel into contact with the unnecessary parts at both sides of the rotating mold. In this case, in order to prevent the side seal 1 from damage caused by bringing adhesive solidified steel into contact with the thin slab on the rotating mold 2, circulation of the heated and stirred molten steel is executed or electric heater is arranged in the side seal or the end parts of the rotating mold are constituted by non-water cooled type rings so as not to lower the molten steel temp. The solidified shell of the molten steel is not formed on the side seal and the thin slab is stably and continuously cast. |
