Patent

CA 2324149

There is disclosed a system and method for the solidification and/or granulation of matte, slag, alloys, bullion, metals in their elemental state and any other metal intermediate or compound. The system comprises a set of twin-drums rotating in opposite direction outwardly or inwardly, and onto which molten matte or slag is poured. The drums are sealed under vacuum and contain a working substance and a wick structure. The drums are also provided with a blade adjacent their external surface so that the solidified matte or slag is granulated when stripped from the surface of the drums. The granulated material can then be recovered in any conventional manner. Alternatively, a near net shape sheet may be produced.

L'invention concerne un système et un procédé pour la solidification et/ou la granulation de matte, de scorie, d'alliages, de métaux dans leur état élémentaire et de tout autre métal intermédiaire ou composé. Le système comprend un ensemble de double tambour rotatif tournant en sens opposé vers l'extérieur et l'intérieur et sur lequel on verse la matte ou la scorie en fusion. Les tambours sont scellés sous vide et contiennent une substance de travail et une structure de mèche. Les tambours sont aussi équipés d'une lame adjacente à leur surface extérieure de manière que la matte ou la scorie solidifiée soit granulée lorsque qu'elle est retirée de la surface des tambours. La matière granulée peut ensuite être enduite de façon conventionnelle. On peut également produire une feuille d'une grande précision dimensionnelle.
