  • Method for casting a melt by means of a melt container in which a melt receiving space is formed
    Patent number: 11931796
    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.
