A twin drum type continuous casting method is provided in which dimples can be formed on a cooling drum surface so as to prevent occurrence of cracks in a thin metal plate which is being cast, wherein there is no need of detecting temperature distribution of a cast piece surface nor of controlling shot particles blasting position onto the cooling drum surface. In the twin drum type continuous casting method in which a molten metal is poured in a molten metal storage portion (50) formed between a pair of cooling drums (1, 1') rotating in opposite directions to each other and a thin metal plate (40) is discharged downward thereof, a casting is done 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 said cooling drum (1, 1') so as to form dimples on said surface (2), thereby preventing occurrence of cracks in the cast piece (40). Also, a brushing device (5) abutting on the outer circumferential surface (2) of the cooling drum (1, 1') cleans said surface (2). <IMAGE> |
