Abstract

To avoid interactions between the oxygen/nitrogen of the atmosphere and molten metal in a casting ladle (1) which is provided with a cover (2), a positive pressure is generated in the interior of the cover and gas is continuously extracted from around the cover (2) without reducing the positive pressure under the cover.
