Abstract

L'invention concerne un procédé de solidification dirigée d'une masse métallique en fusion (1) dans un moule (2). On prépare la masse en fusion (1) à haute température dans un moule (2) et on dirige sa solidification en plongeant le moule (2) dans un bain (3) de liquide réfrigérant réglé à une seconde température inférieure. Pour ajuster cette seconde température, on procède à un échange thermique entre le produit réfrigérant et un agent d'échange thermique (19) inorganique. Indépendamment ou en complément de cette opération, on utilise comme produit réfrigérant de l'oxyde de bore ou un sel inorganique contenant un hydroxyde alcalin, un nitrite alcalin ou un nitrate alcalin. L'invention concerne également un dispositif pour la mise en oeuvre de la solidification dirigée d'une masse en fusion (1).
