Abstract
Konverter-Schwimmkegel bestehend aus einem aus feuerfestem Material bestehenden Schwimmkörper (1 bzw. 1'), der einen durchgehenden Kanal aufweist, in den eine aus dem Schwimmkörper (1 bzw. 1') oben und unten vorstehende Führungsstange (2) einsetzbar ist, die in ihrem unteren Bereich mit einer feuerfesten Umkleidung (3) versehen ist, dadurch gekennzeichnet, dass die Führungstange (2) mit ihrer Umkleidung (3) in den Schwimmkörper (1) einschraubbar ist.Converter floating cone consisting of a consisting of refractory material floating body (1 or 1 ') having a continuous channel into which a from the float (1 or 1') above and below projecting guide rod (2) can be inserted, the is provided in its lower part with a refractory casing (3), characterized in that the guide rod (2) with its casing (3) in the floating body (1) can be screwed.
Description
Die Erfindung betrifft einen Konverter-Schwimmkegel gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a converter-floating cone according to the preamble of claim 1.
Es handelt sich dabei um einen aus zwei getrennten Transporteinheiten zusammengesetzten Schwimmkegel, um die Transport- und Lagerkosten zu reduzieren.It is a floating cone composed of two separate transport units to reduce transport and storage costs.
Bei einem derartigen in der
Der Erfindung liegt die Aufgabe zugrunde, einen demgegenüber ebenfalls aus zwei getrennten Transporteinheiten bestehenden, vereinfachten Schwimmkegel zu schaffen.The invention has for its object to provide a contrast also consisting of two separate transport units, simplified floating cone.
Zur Lösung dieser Aufgabe dienen die Merkmale des Anspruchs 1.To solve this problem serve the features of claim 1.
Die erfindungsgemäße Verwendung eines feuerfesten, vorzugsweise keramischen Gewindes erhöht die Betriebssicherheit insbesondere im Vergleich zu bekannten Schwimmkegeln, bei denen die metallische, durch den Kegel geführte Führungsstange mit einer metallischen Schraube gesichert ist, die im Konverterbetrieb aufschmelzen kann, so dass die Führungsstange verloren geht und damit das angestrebte Ziel, nämlich Verhinderung des Schlackenmitlaufens, nicht erreicht wird.The inventive use of a refractory, preferably ceramic thread increases the reliability especially in comparison to known floating cones in which the metallic, guided by the cone guide rod is secured with a metallic screw that can melt in the converter operation, so that the guide rod is lost and thus the desired goal, namely prevention of slagging, is not achieved.
Eine bevorzugte Ausführungsform des erfindungsgemäßen Konverter-Schwimmkegels ist in Anspruch 2 behandelt.A preferred embodiment of the converter floating cone according to the invention is treated in
