Double rotative drum conticaster and continuous casting method

And cross-fading can quickly correct the twin drum type continuous casting apparatus of water cooling drum thermal deformation, is formed adjacent to the outer periphery of this thin-walled portion has a water cooling drum. There are installed a hot water flow passage of the thin annular member in the space between the thin portion and the shaft portion. There let cooling water flows in the water-cooled drum to water courses and water-cooled Road and drainage channels. A space portion formed between the end face of the annular body and the water cooling drum. This results in deformation of the water cooling drums during casting, by hot water flowing through the annular body and annular body produced is transmitted to the deformation of the thin-walled portion is corrected.
