Method for the directed solidification of molten metal and a casting apparatus for the practice thereof

摘要

A casting apparatus has within a heating chamber (6) and a mold (5) which can be removed from the heating chamber into a molten quenching metal (10) disposed underneath it. As a thermal barrier between the heating chamber (6) and the quenching metal (10), a thermal insulating layer (13) floating on the molten quenching metal (10) is provided, through which the mold (5) plunges into the molten quenching metal (10).
