    摘要: A device for directional solidification of a fused metal, for example a CoCrAlY alloy, which has been poured into a molding shell, by moving the molding shell out of a heating chamber and by immersing the molding shell in a liquid-metal bath serving as a cooling melt with a lower melting-point than the fused metal in the molding shell, for example tin. The liquid-metal bath is enclosed by several current carrying toroidal coils arranged coaxially relative to one another. For the purpose of orienting the stream filament of the agitated fused metal one or more guide plates are arranged in the space between the lateral circumferential surface of the molding shell and the inner wall of the shell containing the liquid-metal bath which is located opposite the molding shell.
