PURPOSE:To prevent the wear of water cooling rolls and to improve the accuracy of a sheet thickness by rotating a pair of the water cooling rolls in synchronization to allow respective solidified shells to form and pressing and uniting both shells with the other rolling down rolls provided above said rolls. CONSTITUTION:A pair of the water cooling rolls 11 are disposed parallel and horizontally at a prescribed space and are immersed into a molten metal 13 in a molten metal vessel 12. Two sheets of the solidified shells 14, 14 cooled by contacting with the lower surfaces of the rolls 1 are pulled up as the rolls 11, 11 rotate synchronously. These shells are pressed and united by the separated provided small-diameter rolling-down rolls 15, 15. The shells 14 are rolled down in a high temp. state in the stage. Since the rolling force does not act on the rolls 15, the surface wear of the rolls 11 is prevented. Since the shells are pressed by the rolls 15 to be exclusively used, the accuracy of the sheet thickness is improved. |
