PROBLEM TO BE SOLVED: To enhance the stability at the time of starting the casting using a dummy sheet in a twin drum type continuous casting device. SOLUTION: The twin drum type continuous casting device is composed of pair of cooling drums having a function of mutually rotating in the opposite direction and side weirs arranged on both ends of the upper space between a pair of the cooling drums. A fluid jet nozzle for cooling a cast slab is provided immediately beneath the cooling drums. The fluid jet nozzle for cooling has a retreat function. Also, the cast slab, which is continuously discharged from the cooling drums to the dummy sheet, is cooled by blowing a cooling fluid at a place immediately beneath the drums. Then, the continuous casting is started. COPYRIGHT: (C)2005,JPO&NCIPI
