Abstract

The present invention provides a twin-drum type continuous casting apparatus in which, when a side weir is vibrated at a high speed, vibrations of the side weir in the axial direction of the cooling drums is suppressed. The generation of run-out from a cast piece is prevented, and the elongation of the lives of the side weirs and the refractory materials is made possible. A pair of side weirs vibrating along end surfaces of cooling drums are characterized in that a support shaft serving as a center of rotation of the vibrations of the side weirs is disposed lower than the molten metal surface and higher than a minimum gap position of the cooling drums. A vibration exciting shaft for applying vibration to the side weir is disposed lower than the above-mentioned minimum gap position.

Dependent claims

A continuous casting apparatus, comprising:

a pair of juxtaposed cooling drums rotatable in opposite rotational directions, said cooling drums being disposed with a gap therebetween having a minimum gap position, and said cooling drums having end surfaces;
a pair of side weirs mounted for vibration along said end surfaces of said cooling drums;
a basin formed by said cooling drums and said side weirs for receiving molten metal and ejecting a cast piece through said gap between said cooling drums;
support shafts rotatably connected to respective said side weirs supporting said side weirs for rotational vibration about a point located above said minimum gap position;
and
a vibration connection on each said side weir connecting said side weir to a vibration applying mechanism, said vibration connection being disposed on said side weir below said minimum gap position.
