Abstract (en)
1. A method for the continuous casting of metal in singlestrand or multi-strand installations wherein the metal, especially steel, is poured from a casting vessel (2) through a casting tube (4) into at least one oscillating mould (1) having a closed-off gas-filled cavity (5) which is located above the bath level (6) in the mould and is under pressure and into which inert gas is introduced during casting and is then separated off upwardly into the atmosphere in the form of bubbles flowing in the direction opposite to that of the metal flowing into the casting tube, characterized in that, by means of a constant inflow of gas, the gas pressure in the cavity is held constantly and automatically at a value equal to the static pressure of the column of metal, irrespective of the height of the column of metal above the bath level in the mould.
Abstract (de)
Beim Stranggiessen von Metall in Ein- oder Mehrstranganlagen wird das Metall durch ein Giessrohr (4) aus einem Giessgefäss (2) in eine oszillierende Kokille (1) gegossen Oberhalb der Kokille (1) liegt ein abgeschlossener, unter Druck stehender, gasgefüllter Raum (5). Dieser ist von einer beweglichen Hülle (3) mit einer Gaszuleitung (8), versehen mit einer Dosiereinrichtung (10), umgeben. Der Durchflussquerschnitt (14) des Giessrohres (4) ist grösser oder gleich dem Produkt aus Kokillenquerschnitt mal der Giessgeschwindigkeit geteilt durch die Geschwindigkeit des strömenden Metalls im Giessrohr (4).
