Abstract

Die Erfindung betrifft einen wassergekühlter Deckel (10) für ein Behandlungsgefäss (1) für Metallschmelzen, wobei das vorzugsweise feuerfest ausgemauerte Behandlungsgefäss (1) insbesondere zur Behandlung von flüssigem Metall, insbesondere von Stahl durch Einblasen von Feststoffen oder Gasen oder induktivem Rühren an Atmosphäre oder im Vakuum dient. Erfindungsgemäß ist es vorgesehen, dass der Deckel (10) domartig ausgebildet ist, wobei das Verhältnis von innerer lichter Höhe (h) zu innerem lichten Durchmesser (D) eines Flansches (12) des Deckels (10) mindestens 0,2 beträgt, dass eine Innenwand (14) des Deckels (10) auf der der Metallschmelze zugewandten Seite im wesentlichen glatt, ri!!en- und spaltfrei ausgebildet ist, und dass auf der Außenseite der Innenwand (14) angeordnete Kühlkanäle (15) vorgesehen sind, durch die die Oberflächentemperatur der Innenwand (14) auf eine Temperatur von maximal 350°C gehalten wird.

The invention relates to a water-cooled lid (10) for a treatment vessel (1) for molten metal, wherein the preferably refractory lined treatment vessel (1) in particular for the treatment of liquid metal, in particular of steel by blowing in solids or gases or inductive stirring in the atmosphere or Vacuum is used. According to the invention, it is provided that the cover (10) is formed like a dome, wherein the ratio of inner clear height (h) to inner clear diameter (D) of a flange (12) of the lid (10) is at least 0.2 that a Inner wall (14) of the lid (10) on the side facing the molten metal is substantially smooth, ri! En- and gap-free, and in that on the outside of the inner wall (14) arranged cooling channels (15) are provided, through which the Surface temperature of the inner wall (14) is maintained at a temperature of 350 ° C maximum.
