Abstract

L'invention concerne un procédé et un dispositif d'extrusion hydrostatique continue On utilise la pression du fluide hydrostatique pour appliquer fortement l'ébauche à extruder sur les parois ou le fonds d'une saignée pratiquée dans un rotor, de façon telle que ladite ébauche soit entraînée par le rotor sans glissement en direction d'une chambre d'extrusion d'où l'ébauche est spontanément extrudée au travers d'une filière. Application à l'extrusion, en continu, notamment de métaux et alliages, y compris de ceux qui présentent une faible ductilité.
