PURPOSE:To obtain an ingot having a good surface characteristic by disposing refractories to the meniscus part of the molten metal surface of a continuous casting device for a thin sheet and disposing electromagnetic stirrers to the upper part of the molten metal surface thereby forming solidified shells under the molten metal surface and maintaining the uniform temp. of a molten metal. CONSTITUTION:The refractories 10, 10' are disposed to the meniscus part of the surface of the molten metal 4 poured from a tundish 5 into the space formed of water-cooled casting drums 1, 1' and stationary gates 2, 2' so that the solidified shells grow from below the meniscus. Since the molten metal 4 is stirred by using the electromagnetic stirrers 9, 9', the temp. of the molten metal 4 is made uniform and the solidification on the molten metal surface is prevented; at the same time, the fluctuation of the molten metal surface is suppressed by the refractories 10, 10'. |
