US 5,964,277 A · Twin drum type continuous casting method

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).

Dependent claims

A twin drum type continuous casting method comprising:

supplying a molten metal in a molten metal storage portion formed between a first cooling drum and a second cooling drum;
rotating said first and second cooling drums in opposite directions to each other such that a thin metal plate is discharged downward from between said first and second cooling drums;
continuously blasting an entire width of an outer peripheral surface of said first cooling drum with shot particles from at least two positions, wherein the shot particles are blasted in a blasting density of 0.05 to 10%;
and
continuously blasting an entire width of an outer peripheral surface of said second cooling drum with shot particles from at least two positions, wherein the shot particles are blasted in a blasting density of 0.05 to 10%.
