A device for positioning the die block (5) of a pouring table (1) relative to a vertical withdrawal axis (X-X) in an uphill vertical continuous casting machine for casting tubes (T) is disclosed. The die block (5) of the machine is supplied by a liquid metal feed device (3) and engages same. The positioning device includes a retractable holder (15) in which the die block (5) is fixed, a movable frame (6) supporting the liquid metal feed device (3), means (18, 19) for positioning the holder (15) relative to the frame (6), locking members (21, 25) for locking the holder (15) and the frame (6) in their respective positions such that the holder (15), the frame (6) and the liquid metal feed device (3) form a unitary assembly, a base (40) arranged in a predetermined position relative to the vertical withdrawal axis (X-X) for supporting said unitary assembly, and alignment means (47, 60, 64) for aligning the axis (Y-Y) of the die block (5) with the vertical withdrawal axis (X-X).
L'invention concerne un dispositif de positionnement, par rapport à un axe vertical (X-X) d'extraction, d'un bloc-filière (5) d'une table de coulée (1) d'une machine de coulée continue verticale ascendante de tubes (T), machine dont le bloc-filière (5) est alimenté, au moyen d'un dispositif (3) de fourniture de fonte liquide, et est en appui sur celui-ci. Ce dispositif de positionnement comprend un support escamotable (15) dans lequel est fixé le bloc-filière (5), un châssis déplaçable (6) sur lequel est posé le dispositif (3) de fourniture de fonte liquide, des moyens (18, 19) de positionnement relatif du support (15) par rapport au châssis (6), des organes de blocage (21, 25) destinés à bloquer la position relative entre le support (15) et le châssis (6) de telle sorte que le support (15), le châssis (6) et le dispositif (3) de fourniture de fonte liquide forment un ensemble monobloc, un socle (40) disposé de façon prédéterminée par rapport à l'axe vertical (X-X) d'extraction et destiné à porter l'ensemble monobloc, et des moyens d'alignement (47, 60, 64) de l'axe (Y-Y) du bloc-filière (5) et de l'axe vertical (X-X) d'extraction.
