Claim 5:
6. The metal casting installation according to claim 1, wherein the ladle sliding gate (15) comprises,
(a) an upper plate (15u) comprising,
a fixing surface and a bottom sliding surface separated from one another by a thickness of the upper plate,
an upper bore extending from the fixing surface to the bottom sliding surface, and wherein
the fixing surface of the upper plate is rigidly fixed to a lower portion of the corresponding first or second ladle (11, 12) with the upper bore in fluid communication with the opening,

(b) a lower plate (15d) comprising,
a nozzle sliding surface and a top sliding surface separated from one another by a thickness of the lower plate,
a lower bore extending from the top sliding surface to the nozzle sliding surface, wherein
the lower plate (15d) is slidingly mounted such that the top sliding surface can slide in translation along the bottom sliding surface to bring the lower bore in and out of fluid communication with the upper bore, and wherein

(c) a drawer (15w) configured for rigidly holding a ladle shroud (13a-13c) having a shroud bore opening at an upper shroud surface and a collector nozzle (14) having a collector bore opening at an upper collector surface, the drawer being movingly mounted such as to translate the upper shroud surface and collector surface along the nozzle sliding surface of the lower plate (15d) between a shroud position, wherein the shroud bore is in fluid communication with the lower bore and a collector position, wherein the collector bore is in fluid communication with the lower bore,
(d) the driving device (17) being coupled to the lower plate (15d) for driving the translation of the lower plate, and
(e) a drawer driving device (17w) being coupled to the drawer (15w) for driving the translation of the drawer,, wherein the driving device (17) is coupled to the lower plate (15d) and comprises a cylinder (17c) rigidly and reversibly coupled to the bottom portion of the corresponding first or second ladle (11, 12), and a piston (17p) rigidly and reversibly fixed to the lower plate (15d), the driving device being configured for moving the lower plate to bring the lower bore in and out of registry with the upper bore, and, wherein the drawer driving device (17w) is coupled to the drawer (15w) and comprises a cylinder (17c) rigidly and reversibly coupled to the bottom portion of the corresponding first or second ladle (11, 12), and a piston (17p) rigidly and reversibly fixed to the drawer (15w), the drawer driving device being configured for moving the drawer to bring the shroud bore and the collector bore in and out of registry with the lower bore.
