PURPOSE:To smooth the surface of a cast thin plate in a continuous casting method by which a molten metal is solidified on one side on a moving metallic plate by rolling the solidified shell after thorough solidification or just before the thorough solidification by means of rolls. CONSTITUTION:A belt 11 for casting is driven by mold driving wheels 12 and rotates upward. When the unsolidified melt 14 in a tundish 13 is charged on the surface thereof, the molten metals falls by a specified distance on the mold surface according to gravity but the mold surface moves upward and therefore the top end 17 of the molten steel arrives at a falling point 19 for the molten steel. The molten steel advances thereafter in the direction of an arrow and solidifies. The solidified steel is rolled with rolls 23, 23' and rolls 22, 22' and further the thin plate is rolled with rolls 21, 21' where the plate detaches from the belt 11. Such thin plate is coiled on a coiler 16. |
