PURPOSE:To provide a twin roll type continuous casting apparatus, in which the thermal deformation of the water cooling roll can quickly and smoothly be corrected. CONSTITUTION:The thin thickness part 1A is formed near the outer periphery in the width direction of the water cooling rolls 1 in the twin roll type continuous casting apparatus. An annular body 5 is inserted in the space part B between this thin thickness part 1A and a shaft 4. In the inner part of the annular body 6, heated water flowing groove 5a is formed. Further, in the water cooling roll 1, a water supplying passage 1b, water cooling passage 1c and drainage passage 1d are supplied. A space part is arranged between the annular body 5 and the end surface of the water cooling roll 1. The thermal deformation of the water cooling roll 1 caused by the continuous casting is corrected by transmitting the deformation of the annular body 5, which is developed by passing the heated water through the annular body 5, to the thin thickness part 1A. |
