Abstract[English]
The present invention relates to a cold crucible for casting in vacuum or in inert atmosphere pure metals and metal alloys, including refractory alloys, which require a high degree of purity. Thanks to a complex geometry made by additive manufacturing and defined with electromagnetic simulations of the melt-crucible-inductor-generator system, the invention greatly improves the transfer efficiency of the electromagnetic energy to the melt and the heat exchange necessary to keep the crucible cold. The crucible according to the present invention makes melting and handling of the melt more efficient and economical and enables production of very high purity melting products having a mass of the order of kilograms.[French]
La présente invention concerne un creuset froid pour la coulée sous vide ou sous atmosphère inerte de métaux purs et d'alliages métalliques, y compris d'alliages réfractaires, qui nécessitent un degré élevé de pureté. Grâce à une géométrie complexe réalisée par fabrication additive et définie avec des simulations électromagnétiques du système masse fondue-creuset-inducteur-générateur, l'invention améliore considérablement le rendement de transfert de l'énergie électromagnétique vers la masse fondue et l'échange de chaleur nécessaire pour maintenir froid le creuset. Le creuset selon la présente invention rend la fusion et la manipulation de la masse fondue plus efficace et économique et permet la production de produits de fusion de très haute pureté ayant une masse de l'ordre des kilogrammes.
