ABSTRACT:
A molten metal is poured in a molten metal storage portion (50) formed between a pair of cooling drums (1, 1') which rotate in opposite directions to each other and a thin metal plate (40) is discharged downward thereof. A casting operation is performed while shot particles (30) are being blasted by a shot particles blasting device (15) from at least two positions onto an entire widthwise outer circumferential surface (2) of each cooling drum (1, 1') so as to form dimples on the circumferential surface (2), thereby preventing the occurrence of cracks in the cast piece (40). Also, a brushing device (5) is disposed in abutting relation on the outer circumferential surface (2) of the cooling drum (1, 1') in order to clean the surface (2).
