Patent

CA 2491644

The invention relates to a method for fractional crystallisation of an at most partially solidified molten metal. According to the invention a layer of at most partially solidified molten metal to be crystallised is cooled by a layer of cooling liquid, which is present above and/or below the layer of at most partially solidified molten metal so as to crystallise the molten metal.

L'invention concerne un procédé permettant la cristallisation fractionnée d'un métal en fusion pouvant être au maximum partiellement solidifié. Ce procédé consiste à refroidir une couche de métal en fusion éventuellement partiellement solidifié au moyen d'une couche de liquide de refroidissement présente au-dessus et/ou au-dessous de la couche de métal en fusion, de manière à cristalliser ce dernier.
