PCT No. PCT/DE91/00814 Sec. 371 Date Oct. 29, 1992 Sec. 102(e) Date Oct. 29, 1992 PCT Filed Oct. 15, 1991 PCT Pub. No. WO92/07099 PCT Pub. Date Apr. 30, 1992.A system for inerting a casting vessel, such as a traversable ladle or torpedo vessel, used for transporting molten metal, the vessel being positioned below the molten metal outlet opening at a transfer station, and the vessel cavity being flushed with an inert gas both prior to the molten metal inletting and during the inflow of the molten metal in such a manner as to avoid contact between the molten metal surface and the vessel and the atomospheric oxygen. A blowpipe is arranged in the vicinity of the molten metal outlet opening but does not intersect the molten metal stream, is located outside the free space profile of the vessel at least during the approach and return of the vessel, and terminates a distance from the vessel inlet opening and produces at its terminal end an inert gas stream which enters the cavity of the vessel adjacent the molten metal stream at an acute angle.
