VERFAHREN ZUR FRAKTIONIERTEN KRISTALLISATION EINES METALLS

摘要

The invention relates to a method for fractional crystallisation of an at most partially solidified molten metal, in which a layer of at most partially solidified molten metal having an upper surface and a lower surface is divided into a series of compartments communicating with each other, in which the metal is stirred in at least some of the compartments, and in which crystals formed in the layer of metal are selectively transported in a predetermined direction and molten metal is selectively transported in the opposite direction.
