PURPOSE:To eliminate the labor and space for taking up by constituting a casting mold of a freely rotatable core and a gate of which the aperture on one side face contacts with the core, pouring a molten metal into the casting mold, rotating the core, drawing a band steel from the inside of the casting mold and taking up directly the band steel on the core. CONSTITUTION:The gate 5 is moved in an arrow B direction by a cylinder 4 and the aperture 7 of the gate 5 is fitted to the core 1. The dummy bar is positioned within the gate 5. The molten metal 27 is poured from a tundish 10 into the casting mold 9 and the core 1 is rotated in an arrow A direction when the molten metal level comes to the height position of the dummy bar. Then the shell formed on the surface of the core 1 is pulled by the dummy bar and the band steel 8 consisting of the shell is taken up on the surface of the core 1. A hammer 25 contacts first with the taken up steel 8, by which the surface is smoothed and the quality is improved. The surface of the band strip is successively cooled with water by a cooler 11 and the oxide film is stripped by a scale breaker 16. A stripping agent consisting of refractories is sprayed from a stripping agent supply device 19. The steel 8 is taken up on the core 1 in the above-mentioned manner.
