PURPOSE:To continuously cast a metallic strip having optional strip width under stable condition by arranging side weir over from a side face of one side cooling roll shifted mutually toward axial direction to a circumferential face of the other cooling roll and vibrating these toward circumferential direction. CONSTITUTION:Molten metal supplied into a space between one pair of cooling rolls 1, 2 arranged to parallel is rapidly cooled and solidified and passed through the roll gap to obtain the metallic strip. In the above production method, the cooling rolls 1, 2 are arranged as shifting mutually toward the axial direction. Further, the side weirs 3, 3 over from the side faces 1a, 2a of one side cooling rolls 1, 2 to the circumferential face 2b, 1b of the other roll 2, 1 are arranged to form the molten metal pool 4. Then, the length L between the side weirs 3, 3 is set to length corresponding to the strip width of aimed metallic strip. Further, the side weirs 3, 3 are vibrated toward the arrow mark circumferential direction along the above circumferential faces 1b, 2b. In this way, the sticking of solidified shell is prevented and the stable casting for a long time can be executed. |
