Zusammenfassung:A directional solidification furnace is disclosed that includes one or more movable insulating members disposed beneath a bottom portion of the crucible. In a first position, the insulating members restrict the flow of heat away from the bottom portion of the crucible. In a second position, the insulating members do not restrict the flow of heat away from the bottom portion of the crucible. An actuating system is used to move the insulating members between the first position and the second position. La présente invention concerne un four de solidification directionnelle qui comporte un ou plusieurs éléments d'isolation mobiles disposés sous une partie de fond du creuset. Dans une première position, les éléments d'isolation maintiennent le flux de chaleur à distance de la partie de fond du creuset. Dans une seconde position, les éléments d'isolation ne maintiennent pas le flux de chaleur à distance de la partie de fond du creuset. Un système d'actionnement sert à déplacer les éléments d'isolation entre les première et seconde positions.
