Abstract: A multi-coupling has an alignment aid with first and second coupling parts compensating for offset tolerances during coupling of medium couplings. At least one coupling part has a coupling carrier mounted floatingly transversely with respect to the coupling direction, and the alignment aid has, on one coupling part, a central precentring journal protruding in the coupling direction and a precision centring journal protruding from a coupling carrier in the coupling direction and arranged radially around the precentring journal axis. The precision centering journal head is set back in the coupling direction with respect to the precentring journal head, and the alignment aid has, on the coupling socket side, a central jaw that merges into a precentring guide for the precentring journal and is equipped with at least one precision centering guide, arranged around the precentring guide axis, for the precision centering journal.

Abstract: A multi-coupling (1)-couples lines (2) with an alignment aid (5) assigned to a first coupling part (3) and a second coupling part (4) for compensating for offset tolerances during threading of the first coupling part (3) into the second coupling part (4) during coupling of medium couplings (6). At least one coupling part has a coupling carrier (8) mounted floatingly transversely with respect to the coupling direction (7), and the alignment aid (5) has, on one coupling part, a central precentring journal (9) protruding from a coupling carrier in the coupling direction (7) and at least one precision centring journal (11) protruding from the coupling carrier (8) in the coupling direction (7) and arranged radially around the precentring journal axis (10).

Abstract: The invention relates to a method for producing foundry ingots (1) from metal, in particular from steel, having a cross-sectional area of more than 0.1 m2, wherein liquid metal (2) is discharged into an ingot mold (15) open at the bottom either directly form a casting ladle (11) or via a tundish (12), and wherein, by a drawing piston (28), which is vertically movable in the direction of a longitudinal axis (5) of the foundry ingot (1) and on which the foundry ingot (1) is at least indirectly arranged, the at least partially solidified foundry ingot (1) is drawn from the ingot mold (15) in the direction of the longitudinal axis (5).
