PURPOSE: To enable continuous casting for a long time by making that length of a cooling roll in the axial direction twice or more the of a molten metal pouring width, enabling the roll to be horizontally shifted in the axial direction to the nozzle and cleaning the roll surface in the range of no pouring.
CONSTITUTION: The cooling roll 1 is rotated with driving motor 5. The molten metal poured on a pouring position 8 from the nozzle is cooled with the cooling roll 1 and rapidly solidified to make a thin metal strip 6. The roll surface of the cooling roll part 1 shown with the slant lines in a figure is cleaned and renewed with a blade 2 for shaving. Successively, the cooling roll 1 is shifted to a prescribed position with respect to the pouring position 8 of the nozzle with an oscillating device 4. During this shifting, the cooling roll 1 is rotated at a fixed speed and the thin metal strip 6 is continuously produced. Further, the blade 2 for shaving is temporarily separated from the roll 1 and shifted on a shifting table 3 and the roughened roll surface is shaven and renewed.
