PURPOSE:To make continuous casting of a thin metallic sheet easy and sure by acting a uniform pressure of the melt of an inorg. material upon the top surface of the molten metal supplied on the surface of a water cooled mold of a flat plate shape. CONSTITUTION:The molten metal 12 in a tundish 11 for molten metal flows out through a molten metal outflow hole 13 onto the mold surface 14a of a water cooled mold 14. A uniform pressure is acted upon an ingot 16 which is cooled and solidified on the mold surface 14a of a flat plate shape, by the differential pressure generated by a difference between the head of the molten metal 12 in the tundish 11 and the head of the melt 18 of an inorg. material in a tundish 20 for the melt of the inorg. material. While the ingot 16 is formed to a uniform thickness, the ingot is drawn to the outside through an ingot drawing port 14c, and is rolled with rolling roll devices 25. In this case, the thickness of the ingot 16 is determined by the pressure of the melt 18. |
