TWIN-DRUM TYPE CONTINUOUS CASTING APPARATUS

摘要

The present invention intends to provide a twin-drum type continuous casting apparatus, in which even when a side weir is vibrated at a high speed, vibration of the side weir in the axial direction of the cooling drums is suppressed, generation of run-out in a cast piece is prevented, and thereby elongation of lifes of the side weirs and refractory materials is made possible. The subject matter is a twin-drum type continuous casting apparatus including a pair of side weirs (52) vibrating along end surfaces of cooling drums (51), characterized in that a support shaft (6) serving as a center of rotation of the vibration of the side weir (52) is disposed lower than a molten metal surface and higher than a minimum gap position of the cooling drums (51), and a vibration exciting shaft (2) for applying vibration to the side weir (52) is disposed lower than the above-mentioned minimum gap position.
