Abstract

Mehrstufiger Rotor für die Reinigung von Metallschmelzen, dadurch gekennzeichnet, dass der Rotor in mindestens zwei Segmente mit unterschiedlichen Durchmessern gegliedert ist.Multi-stage rotor for cleaning metal melts, characterized in that the rotor is divided into at least two segments with different diameters.

Description

Die Reduzierung nichtmetallische Einschlüsse war schon immer eine Aufgabe für die Verbesserung der metallischen Eigenschaften. Eine optimierte Reinigung von Metallschmelzen erfolgt durch ein Rotorsystem über das Inertgase (Ar, N2, Cl2) in die Schmelze geleitet werden. Diese Spülgase binden nichtmetallische Komponenten und transportieren sie zur Schmelzbadoberfläche, wo sie entfernt werden können.The reduction of non-metallic inclusions has always been a task for the improvement of metallic properties. An optimized cleaning of metal melts is carried out by a rotor system via the inert gases (Ar, N 2 , Cl 2 ) into the melt. These purge gases bind non-metallic components and transport them to the molten bath surface where they can be removed.

Neu und erfindungsgemäß ist die mehrstufige Form des Rotors mit mindestens zwei Stufen in verschiedenen Durchmessern (siehe Zeichnung). Durch die mehrstufige Form werden die aufsteigenden Gasblasen mehrmals zerstört, gleichmäßig verteilt und die Reaktionsfläche vergrößert, Somit können die Verunreinigungen schneller an die Schmelzbadoberfläche abtransportiert werden und es wird ein höherer Reinheitsgrad der Schmelze erzielt.New and inventive is the multi-stage shape of the rotor with at least two stages in different diameters (see drawing). Due to the multi-stage shape, the rising gas bubbles are destroyed several times, evenly distributed and increases the reaction area, Thus, the impurities can be transported faster to the melt surface and it is achieved a higher degree of purity of the melt.
