ABSTRACT:
A twin-roll type continuous casting apparatus comprises a pair of rotatable drums and a pair of side dams disposed on both axial ends of the drums so that a pool of molten steel is defined by the drums and the side dams. As the drums are rotated in counter directions, the molten steel is cooled so that the molten steel is partially solidified to form solidification shells which are then pressure-bonded to each other as they pass through the narrowest gap defined between the drums, so that a steel sheet is formed by continuous casting. The side dam is composed of a side refractory part which functions to maintain the pool of molten steel and a metallic member which supports the side refractory part and which serves as a cooling plate for cooling the steel. The side refractory part is projected inwardly of the pool from the metallic member and arranged so that the lower end thereof is positioned in the vicinity of a point where the pressure-bonding of the solidification shells is commenced, the point being located above the narrowest gap defined between the drums.
