Abstract

L'invention concerne un procédé de fabrication par cristallisation dirigée d'une pièce à structure monocristalline. Selon le procédé, on dispose dans une chambre de chauffage (2) une forme (7) que l'on remplit d'un bain de fusion (8), on déplace cette forme dans une chambre de refroidissement (3) et l'on refroidit cette chambre de refroidissement avec deux flux de refroidissement contenant un mélange d'un gaz inerte et de substances de refroidissement en poudre. Le dispositif destiné à la mise en oeuvre de ce procédé contient un four à vide (1) avec un système de vide (4), une chambre de chauffage (2) et une chambre de refroidissement (3), une forme (7), un système à gaz (12) ainsi que deux dispositifs placés dans la chambre de refroidissement (3) et destinés à diriger sur la forme (7) deux flux de refroidissement indépendants constitués d'un mélange de gaz et de substances de refroidissement en poudre. Le dispositif comprend également deux systèmes disposés l'un sous l'autre en dessous de la paroi (5) à l'intérieur de la chambre de refroidissement (3) et destinés à diriger sur la forme (7) deux flux de refroidissement indépendants.
