Abstract (en)
The invention relates to a method for melting and decanting a metal (7) into a tundish (3), wherein a liquefied inert shielding gas (20) is supplied to a melt of the metal (7) during melting, wherein the liquefied shielding gas (20) is supplied to the metal (7) through at least two different lance outlet nozzles (61, 62, 61a, 62a), wherein the liquefied shielding gas (20) is supplied during melting through one (61, 61a) of the at least two lance outlet nozzles (61, 62, 61a, 62a) to the metal (7) located in a crucible (1) and wherein the liquefied shielding gas (20) is supplied during decanting through another one (62, 62a) of the at least two lance outlet nozzles (61, 62, 61a, 62a) to a flow of the decanting molten metal and/or to the metal (7) located in the tundish (3).
