Abstract

Die Erfindung betrifft ein Verfahren zur Regelung des Durchflusses durch einen Bodenausguss eines metallurgischen Gefäßes mit einer im Boden des metallurgischen Gefäßes angeordneten oberen Düse und einer unterhalb der oberen Düse angeordneten unteren Düse, mit mindestens einer Inertgaseinlassöffnung und mit an oder in der unteren Düse angeordnetem Sensor zur Bestimmung der Schichtdicke von Festsetzungen (clogging) in der Düse, wobei die Inertgaszufuhr in den Bodenausguss geregelt wird anhand der Messsignale des Sensors. Sie betrifft weiterhin einen Bodenausguss für ein metallurgisches Gefäß mit einer im Boden eines metallurgischen Gefäßes angeordneten oberen Düse und einer unterhalb der oberen Düse angeordneten unteren Düse, wobei die Wand der Durchflussöffnung durch die Düsen zumindest metallschmelzflussdicht ausgebildet ist, wobei die Düsen zumindest teilweise von einem gasdichten Gehäuse umgeben sind, das Gehäuse an seinem unteren Ende die untere Düse an ihrem Umfang gasdicht umschließt, wobei es mit einem Teil seiner Innenseite an der Außenseite der Düse anliegt und zwischen der Wand der Durchflussöffnung und dem Gehäuse ein thermisch isolierender Feststoff angeordnet ist.The invention relates to a method for regulating the flow through a bottom spout of a metallurgical vessel with a top nozzle arranged in the bottom of the metallurgical vessel and a bottom nozzle arranged below the top nozzle, with at least one inert gas inlet opening and with a sensor arranged on or in the bottom nozzle Determination of the layer thickness of clogging in the nozzle, whereby the inert gas feed into the bottom nozzle is regulated by means of the measuring signals of the sensor. It further relates to a bottom spout for a metallurgical vessel having a top nozzle disposed in the bottom of a metallurgical vessel and a bottom nozzle disposed below the top nozzle, the wall of the flow opening being at least metal melt flow tight through the nozzles, the nozzles being at least partially gas-tight Enclosed housing, the housing at its lower end, the lower nozzle encloses gas-tight at its periphery, wherein it rests with a part of its inner side on the outside of the nozzle and between the wall of the flow opening and the housing, a thermally insulating solid is arranged.
