BELT TYPE CONTINUOUS CASTING METHOD

PURPOSE:To provide a continuous casting apparatus reducing the rolling reduction force at the time of rolling, in the method for executing the rolling treatment for adjusting strip thickness after casting molten metal. CONSTITUTION:At the time of producing a prescribed strip thickness of the strip 15 by executing the rolling reduction with the rolling rolls, 13 to two solidified shells 12a, 12b developed at the upper and lower parts in a molten metal pouring basin part, 6, the rolling reduction is made to be executed to the solidified shells 12a, 12b under condition of remaining the unsolidified metal 9a between the solidified shells 12a, 12b. At this time, the side surface of a cast strip is supported with the side plates between a belt 4 and rolling rolls 13 to prevent leakage of the molten metal. In this result, by existence of the unsolidified metal 9a, the rolling reduction force is reduced and the service life of the rolling roll 13 is prolonged and the durability is improved.
