Abstract: 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.

Abstract: A method for casting a cast part according to the tilt pouring principle includes pouring a molten metal from at least one tiltable casting vessel into a casting mold including a mold cavity which forms the cast part. The molten metal is ladled directly out of a bale-out furnace using the casting vessel, and a metal oxide skin forms in the casting vessel on the surface of the molten metal. The casting vessel containing the molten metal and the metal oxide skin floating thereon is brought to the casting mold. The molten metal is poured from the casting vessel into the casting mold by a common rotation of the casting vessel and casting mold about an axis of rotation. The metal oxide skin rises to the top of the molten metal during the pouring process, floating predominantly on top and on the surface of the molten metal.
