A method and a device for improving tapping of liquid steel during the entire tapping period of the steel from a smelting furnace into a ladle. Between the tap hole of the furnace and the ladle bottom or the steel in the ladle an oxygen-free atmosphere with a pressure of > 1 bar is maintained. In the device for carrying out the method, a ladle dome is arranged between the furnace tap and the ladle and the ladle is connected to at least one gas supply.
Méthode et dispositif permettant d'améliorer la coulée de l'acier liquide pendant toute la période de coulage de l'acier à partir d'un four de fusion dans une poche de coulée. Entre le trou de coulée du four et le fond de la poche de coulée ou l'acier dans la poche de coulée, une atmosphère exempte d'oxygène à une pression supérieure à 1 bar est maintenue. Dans le dispositif nécessaire à l'application de cette méthode, un dôme de poche de coulée est placé entre le trou de coulée du four et la poche de coulée, et celle-ci est reliée à au moins une source de gaz.
