Claim 11:
12. A method for casting a molten metal comprising
(a) providing a metal casting installation according to claim 1, wherein,
the first ladle is full of molten metal (2) and is in the casting station and
the second ladle (12) is full of molten metal (2) and is in the loading station,
the ladle sliding gate (15) of the first ladle (11) is in the sealed position, is coupled to one or more driving devices (17) and optionally drawer driving devices (17w), and is provided with a ladle shroud (13a-13c) and a collector nozzle (14),
the ladle sliding gate (15) of the second ladle (12) is in the sealed position and comprises no ladle shroud (13a-13c) and no operational driving device (17) and no operational drawer driving device (17w),

(b) bringing the ladle sliding gate (15) of the first ladle (11) into casting position for casting molten metal from the first ladle (11) through the ladle shroud (13a) into the tundish (2),
(c) during the preceding step,
loading with the robot (21) a new ladle shroud (13b) onto the ladle sliding gate (15) of the second ladle (12), and
coupling with the robot (21) the driving device (17) to the sliding plate gate (15) of the second ladle (12),

(d) When the first ladle is substantially empty, bringing the ladle sliding gate (15) of the first ladle (11) into sealed position, followed by
(e) swapping positions of the first and second ladles by moving the first ladle (11) from the casting station to the loading station and, concomitantly, moving the second ladle (12) from the loading station to the casting station,
(f) bringing the ladle sliding gate (15) of the second ladle (12) into casting position and casting molten metal from the second ladle (12) through the ladle shroud (13b) into the tundish (2).
