Abstract:
A device for casting strips of metal, comprising:counter-rotating casting rolls; two side walls, liquid metal being fed into a space between the casting rolls bounded by the two side walls, gaps being formed between the side walls and the casting rolls; and a sealing device sealing each of the gaps, the sealing device generating electrodynamic forces which follow a profile of the gaps and act parallel to surfaces of the casting rolls, the sealing device including a Y-shaped current-carrying inductor having two branches above a base, the inductor being arranged at an axial end of said rolls and having a spacing in the axial direction of said rolls between said axial ends and said inductor, the inductor being configured such that said spacing in the axial direction of said rolls increases from an intersection of said branches and said base, toward both top ends of said branches and toward a bottom end of said base, thereby providing electrodynamic forces on said liquid metal which are continuously adapted to metallostatic pressure of the liquid metal.
