Abstract

La présente invention concerne un procédé permettant de retirer un moule (10) d'une coulée (11) formée à l'intérieur de ce moule. Le moule peut être retiré de la coulée par la découpe de ce moule et par application d'une force suffisante pour entraîner une fracture de ce moule qui se casse en morceaux. Par ailleurs, le moule peut être fracturé soit par des charges explosives (22) placées dans l'enveloppe du moule, soit par des pulsations de hautes énergie dirigées sur ce moule. Lorsque ce moule est fracturé et cassé en différents morceaux il peut être retiré de la coulée.
