A method for casting a melt uses a melt container in which a melt receiving space is formed. The melt container has a spout in the form of a lance on the bottom on the melt container. The method includes the following steps: filling the melt container with melt, wherein the melt is introduced into the melt receiving space of the melt container from a crucible using a spout orifice of the lance; casting at least one cast workpiece with melt; filling the melt container with melt again. When filling the melt container with melt, more melt is received in the melt receiving space than is needed for casting the cast workpiece. Directly before the renewed filling of the melt container, a remainder of melt having an oxide skin formed at the melt surface is present in the melt receiving space of the melt container.

The present invention concerns a metal casting installation comprising, (a) a loading platform (20), (b) a tundish (1), (c) a first ladle (11) and a second ladle (12), each of the first and second ladle comprising, a floor provided with an opening (11o, 12o), a collector nozzle (14) and a ladle shroud (13a-13c), a ladle sliding gate (15) configured for moving the collector nozzle and the ladle shroud between a sealed position wherein the opening is sealed, a casting position wherein the opening faces the ladle shroud (13a-13c), and an unclogging position wherein the opening faces the collector nozzle (14), (d) a turret (30) for holding the first and second ladles, configured for moving and holding in place the first and second ladles (11,12) between a loading station and a casting station, over the tundish (1), Characterized in that, the metal casting installation comprises a robot (21) configured for carrying out the following operations on the first or second ladle which is held in the loading station, loading a new ladle shroud (13b) onto the ladle slide gate (15), and coupling a driving device (17) to the ladle slide gate (15).

A method for producing ultra-thin hot-rolled strip steel, the method comprising the following process steps: A. a smelting process: feeding scrap steel into an induction electric furnace (1) for smelting so that the scrap steel melts into molten steel; B. a refining process: using a ladle refining furnace (2) and a ladle vacuum degassing furnace (3) to refine the molten steel; C. a continuous casting process: casting the refined molten steel into a cast strip blank that has a thickness of 1.6-2.5 mm by means of a dual-roller thin strip continuous casting system (4); D. a hot rolling process: directly feeding the cast strip blank that was cast in the continuous casting process to a single-stand hot rolling mill (9) for rolling to produce hot-rolled strip steel, the thickness of the hot-rolled strip steel being 0.8-1.5 mm; E. a cooling coiling process: performing atomizing cooling on the hot-rolled strip steel, and coiling after the strip steel temperature is controlled to be 400-750° C. The present method achieves an extremely compact, environmentally-friendly and economical ultra-thin hot-rolled strip steel production process flow, and achieves the environmentally-friendly and economical continuous production of metal plates and strips.
