A system and method for producing a metallic ingot using, for example, a VAR furnace, includes a primary crucible receiving a melted metal from a source of metal and collecting the melted metal to for a pool of melted metal, the primary crucible including an overflow lip, a secondary crucible receiving the melted metal from the overflow lip of the primary crucible, the secondary crucible being smaller than and electrically isolated from the primary crucible, and a withdrawal device withdrawing the molten metal, solidified by cooling, from the secondary crucible in the form of solidified ingots, wherein the solidified ingots have a smaller diameter than a diameter of the source of metal. A cutting device periodically cuts the withdrawn solidified ingots as they are withdrawn from the secondary crucible.
Un système et un procédé de production d'un lingot métallique à l'aide, par exemple, d'un four VAR, comprennent un creuset primaire recevant un métal fondu provenant d'une source de métal et recueillant le métal fondu pour former un bassin de métal fondu, le creuset primaire comprenant un bord de débordement, un creuset secondaire recevant le métal fondu provenant du bord de débordement du creuset primaire, le creuset secondaire étant plus petit que le creuset primaire et électriquement isolé de ce dernier, et un dispositif de retrait retirant le métal fondu, solidifié par refroidissement, du creuset secondaire sous la forme de lingots solidifiés. Les lingots solidifiés ont un diamètre inférieur à un diamètre de la source de métal. Un dispositif de découpe permet de découper périodiquement les lingots solidifiés retirés lorsqu'ils sont retirés du creuset secondaire.
